Frequently Asked Questions (FAQs)

PostgreSQL is a powerful open-source relational database management system known for its robust features, reliability, and extensibility. Implementing PostgreSQL in a Flutter app allows developers to securely store and manage data, perform complex queries, and ensure data integrity, making it ideal for a wide range of applications, from simple mobile apps to enterprise-level solutions.
To integrate PostgreSQL with a Flutter app, developers typically use client libraries or plugins that provide connectivity and interaction with the PostgreSQL database. These libraries, such as dart-pgsql or sqflite, enable developers to establish connections, execute SQL queries, and manage database transactions directly from their Flutter code.
Some advantages of using PostgreSQL in a Flutter app include its support for ACID transactions, data integrity constraints, advanced SQL features, scalability, and compatibility with various platforms and programming languages. Additionally, PostgreSQL offers robust security features, including authentication, authorization, and encryption, ensuring the confidentiality and integrity of stored data.
Yes, PostgreSQL can be used with Flutter for both mobile and web apps. While mobile apps typically interact with a remote PostgreSQL server over a network connection, web apps can also utilize PostgreSQL for server-side data storage and management. By leveraging PostgreSQL’s cross-platform compatibility, developers can build Flutter apps that seamlessly integrate with PostgreSQL databases across different platforms.
When implementing PostgreSQL in a Flutter app, developers should consider factors such as database schema design, query optimization, error handling, data synchronization, and security best practices. It’s essential to design an efficient database schema that meets the application’s requirements, optimize SQL queries for performance, handle errors gracefully, ensure data consistency across client and server, and implement proper security measures to protect sensitive data.
While PostgreSQL offers many benefits, developers should be aware of potential limitations or challenges, such as database performance issues, network latency, connectivity issues, and compatibility with different Flutter platforms (iOS, Android, web). Additionally, developers may need to address platform-specific considerations, such as handling offline data storage and synchronization in mobile apps, or optimizing database connections and queries for web apps.
Developers can find resources such as documentation, tutorials, sample code, and community forums to help them implement PostgreSQL in their Flutter apps. Additionally, client libraries and plugins often provide documentation and examples to guide developers through the integration process. By leveraging these resources and seeking assistance from the Flutter and PostgreSQL communities, developers can overcome challenges and build robust, database-driven Flutter apps with PostgreSQL integration.

Flutter BLoC Tutorial: State Management using BLoC Pattern

Document

What is BLoC?

BLoC is the abbreviation of the word Business Logic Components It aims to isolate the business logic of an application from its User Interface, making the application’s code simpler, flexible, adaptable, and capable of being tested.

  • Developed by: Felix Angelov
  • Sponsors: Very Good Ventures, Stream, Miquido
  • Version: flutter_bloc: ^8.0.1(at the time of writing article)

Pros & Cons of BLoC Design Pattern

Before we move on to the Flutter Block tutorial Let’s look at some of the advantages and disadvantages of the block design pattern.

Pros of Using BLoC

Great documentation of various scenarios.

Separates the business logic from the UI which makes the code understandable.

It makes the product more tastier.

It is simple to track the states that an app has gone through.

Cons of Using BLoC

The learning curve is steep.

Not recommended for applications with simple requirements.

A little more boilerplate code, but it is easily handled with extensions.

Flutter BLoC Tutorial Goal

We will create a basic application to demonstrate how the BLoC utilizes streams to manage state and create a few tests for the block.

We will create a basic application to demonstrate how the BLoC utilizes streams to manage state and create a few tests for the block.

Initial Setup

Make sure to install the bloc extension in your editor; it will help create all boilerplate code and files required for the project(right-click on the lib folder, and it will give you the option for generation bloc for your project).

Make sure to match your pubspec.yaml file with mine to avoid any issues.

Understanding BLoC Concepts: Events and States

To understand the way that blocks work We must know what constitutes states and events.

events: These are the inputs that an app can receive (like pressing a button to load images, inputs for text, or any other inputs from users that our application might wish to get).

State: State is the state of the application, and can be altered according to an event that is received.

Bloc manages these states and events, i.e., it is able to take an entire flow of Events and convert them into streams of States as output.

Creating an Event

                    
                        @immutable
                        abstract class AppBlocEvent {
                         const AppBlocEvent();
                        }
                         
                        @immutable
                        class ChangeTextEvent extends AppBlocEvent {
                         const ChangeTextEvent();}
                        
                    
                

Moving forward to the Flutter Block Tutorial. We have made an event called ChangeTextEvent which will be fired whenever the button is pressed.

We use an abstraction of the AppBlocEvent Class since Bloc is expecting a single occasion to add to its stream. However, since there could be multiple events running in an app, we design an abstract class and then extend it when we need to add any new event and pass on multiple events to Bloc.

Creating a State

Event and State Management using BLoC Pattern

                    
                        class AppBlocBloc extends Bloc {
                            final List textList = [
                              'Initial Text',
                              'Changed Text',
                              'Changed Again',
                            ];
                            AppBlocBloc() : super(const AppState.empty()) {
                              on((event, emit) {
                                try {
                                  int newIndex = state.index + 1;
                                  if(newIndex >= textList.length) {
                                    newIndex = 0;
                                  }
                                  emit(
                                    AppState(
                                      index: newIndex,
                                      text: textList[newIndex],
                                    ),
                                  );
                                } on Exception catch (e) {
                                  // ignore: avoid_print
                                  print(e);
                                }
                              });
                            }
                           }
                           
                

Explanation

This is the section which contains the software.

When a it is added into the stream with clicking a button. It gets the event, i.e. the information you wish to share with the triggering events, you are able to access via this(like event.any_info which requires you to alter your event’s class to reflect this) emit is used to generate an event state specific to that event.

It gets the event, i.e. the information you wish to share with the triggering events, you are able to access via this(like event.any_info which requires you to alter your event’s class to reflect this) emit is used to generate an event state specific to that event.

state.index allows you to see the state that is currently in the application’s state.index. It lets you see the current state of the.

emit(AppState (…)): emit (…) is used to generate new states and triggers the rebuilding part of the built() build() function.

Connect the pieces.

At present the events, states, blocks and our application’s UI are not linked to each other in any manner. Let’s get them all connected.

Providing our BLoC

                    
                        import 'package:flutter/material.dart';
                        import 'package:flutter_bloc/flutter_bloc.dart';
                        import 'package:text_change/text_controller.dart';
                        
                        import 'bloc/app_bloc_bloc.dart';
                        import 'bloc/app_bloc_state.dart';
                        
                        class App extends StatelessWidget {
                          const App({Key? key}) : super(key: key);
                        
                          @override
                          Widget build(BuildContext context) {
                            return MaterialApp(
                              title: 'Flutter Demo',
                              theme: ThemeData(
                                primarySwatch: Colors.blue,
                              ),
                              home: BlocProvider(
                                create: (context) => AppBlocBloc(),
                                child: Scaffold(
                                  appBar: AppBar(
                                    title: const Text('Text Change'),
                                  ),
                                  body: BlocConsumer(
                                    listener: (context, state) {},
                                    builder: (context, state) {
                                      return Text Controller(
                                        text: state.text,
                                      );
                                    },
                                  ),
                                ),
                              ),
                            );
                          }
                        }
                        
                        
                    
                

Explanation: App.dart

BlocProvider (…): We use it to display an instance of our block by placing it under the base of the application to make it accessible to all users.

Create: It creates the version of our AppBloBloc.

BlocConsumer (…): It is the place in which everything takes place.

builder: ‘s responsible for creating it’s UI which is then rebuilt with every state changes. blocConsumer also includes listenWhen and buildWhen that, like the name suggests, can be customized to respond to specific state changes.

Triggering the Event and States

                    
                        class TextChangeController extends StatelessWidget {
                            final String text;
                            
                            const TextChangeController({Key? key, required this.text}) : super(key: key);
                            
                            @override 
                            Widget build (BuildContext context) { 
                                  return Column
                                     children:  [ 
                                        TextChange(
                                           text: text, 
                                        ), // TextChange 
                                       ElevatedButton( 
                                           onPressed: () =>
                                                context.read().add(const ChangeTextEvent()), 
                                          child: const Text('Change Text'), 
                                     ), // ElevatedButton 
                                  ), // [ ] 
                               ); // Column
                              )
                            )
                            
                

In this case, we’ve included the event called ChangetTextEventonto an event’s stream which triggers a state change that triggers the rebuilding of BlocConsumer’s builder() inside BlocConsumer and then the modified text will show to the right of the screen.

You’ve got it You’re done! With a separate UI with business logic you can alter the UI code, and then connect the Bloc into. It will operate in the same way.

Testing the BLoC Design Pattern

For testing the bloc, you require two packages:

  • bloc_test
  • flutter_test

Simply go to the folder for testing, make the app_bloc_test.dart file and begin writing the test.Inside we’ll test two requirements:

Initial state of application i.e AppState.empty().State changes when the button is pressed.

                            
                                void main() {
                                    blocTest(
                                      'Initial State',
                                      build: () => AppBlocBloc(),
                                      verify: (appState) =>
                                          expect(appState.state, const AppState.empty(), reason: 'Initial State'),
                                    );
                                    blocTest(
                                      'emits [MyState] when MyEvent is added.',
                                      build: () => AppBlocBloc(),
                                      act: (bloc) => bloc.add(const ChangeTextEvent()),
                                      expect: () => const [
                                        AppState(
                                          index: 1,
                                          text: 'Changed Text',
                                        ),
                                      ],
                                    );
                                   }
                                   
                        

Explanation

  • blocTest is a part of the package bloc_test.
  • Build() It returns an example of AppBlocBloc().
  • Expect and verify in the sense that they are in line with the state expect(actual matcher, actual).
  • Act: To insert an event to the stream

Frequently Asked Questions (FAQs)

BLoC (Business Logic Component) is a design pattern used for managing state in Flutter applications. It helps separate business logic from UI components, making code more modular, testable, and maintainable. BLoC pattern is widely used in Flutter for its simplicity and scalability in managing complex stateful applications.
In the BLoC pattern, business logic is encapsulated within separate BLoC classes, which act as intermediaries between UI components and data sources. BLoC classes receive events from the UI, process them, update the application state, and emit new states to notify UI components of changes.
The key components of the BLoC pattern in Flutter include:
  • Events: Represent user actions or system events that trigger state changes.
  • BLoC: Business Logic Component that contains the application’s business logic and manages state.
  • States: Represent different states of the application, which are emitted by the BLoC in response to events.
  • UI Components: Widgets that display the application’s state and respond to user interactions.
To implement the BLoC pattern in Flutter, you typically define BLoC classes to manage state, create events and states to represent user actions and application states, use StreamControllers or Cubits to handle state changes, and integrate BLoCs with UI components using StreamBuilder or BlocBuilder widgets.
The benefits of using the BLoC pattern in Flutter include separation of concerns, improved code organization and maintainability, reusability of business logic across multiple UI components, testability with unit tests and widget tests, and scalability for managing complex stateful applications.
While Provider and Riverpod are alternative state management solutions in Flutter, the BLoC pattern offers a more structured and formal approach to managing state, particularly for large-scale applications with complex state requirements. BLoC provides better separation of concerns and facilitates better code organization compared to other solutions.
Common use cases for using the BLoC pattern in Flutter applications include managing form state, handling user authentication and authorization, fetching and caching data from APIs, implementing complex user interfaces with dynamic behavior, and coordinating interactions between multiple screens or components.
While the BLoC pattern offers many advantages, it can introduce some complexity, especially for beginners. Setting up BLoC architecture and managing streams can require a learning curve. Additionally, boilerplate code and increased file count may be a concern for smaller projects.
Developers can find tutorials and resources for learning about the BLoC pattern in Flutter on official Flutter documentation, community forums like Stack Overflow and GitHub, developer blogs and tutorials, online courses and certifications, and Flutter conferences and meetups. Additionally, exploring sample projects and GitHub repositories can provide hands-on experience and insights into best practices.
Best practices for using the BLoC pattern effectively in Flutter applications include keeping BLoC classes focused on specific domains or features, minimizing dependencies between BLoC classes, using dependency injection for managing BLoC instances, naming conventions for events and states, and writing comprehensive unit tests to ensure correctness and reliability.

Flutter Performance Techniques To Boost Existing App Outcomes

Neo Infoway - WEB & Mobile Development Company | Festival | Neo | Infoway | Leading software Development company | Top Software development company in India

Introduction

Flutter is now the most used and preferred framework for developing cross-platform applications. Flutter is a framework that runs with the Dart programming language which Google creates. Flutter lowers development costs and allows for flexible the development of applications for every platform. This creates Flutter among the most powerful frameworks for developing applications.

Flutter Vs React Native Performance

Both frameworks are capable of delivering excellent performance. However, Flutter has an advantage because it’s more flexible when working with files that are heavy and require more memory. It is also known as React Native Applications are lighter in weight, but they use greater power, which is not a good thing for performance.

Flutter is compatible with native code which enhances Flutter’s web performance and performance across platforms. Furthermore, Flutter tools are able to be utilized for platforms like embedded (infotainment systems that are used in automobiles).

Top Flutter Performance Optimization Tips

In this section of this blog post, all details have been given to help you improve Flutter’s performance. effectiveness of the Flutter application. and performance of the application.

Avoid State Flutter Widgets

The biggest mistake we make is to use State Flutter widgets to support Flutter App development during the initial stages of the development. Stateful widgets are a good choice when your application is using an extensive build function and you need to build it again.

SetState() and StatefulWidget should be used only to update or rebuild. Additionally, it is recommended to use it only in all widgets to improve efficiency of Flutter.

Use Const Keyword

Const is a constant that is a kind of Flutter widget which is used during compilation to prevent. Const lets you use multiple widgets with no impact on performance. Another advantage of const is it doesn’t require the need to rebuild every time you switch between widgets.

Use case of Const

const EdgeInsets.fromLTRB(16, 4, 16, 8);

How to Handle Offline Data Storage with Flutter Hive?

Introduction

The data storage locally is a necessity for virtually all apps. Storage and manipulating data is a vital aspect of developing apps and is the same for Flutter applications. Perhaps you’d like to cache requests from REST APIs, create an application that runs on the internet or store information about customers in a food delivery service.

Several options are available for developers to persist local data in Flutter.shared_preferences: Provides a good way to store small pairs of keys and values .sqlite : It’s a good choice when your database must handle complex relationships between relational data.

But, if you’re searching for a quick and secure local database that is also suitable using Flutter Web(), in this case, to manage offline data storage using Flutter Hive is among the most effective options available.

What is Hive in Flutter?

Hive is a light and lightning fast key-value database created in the pure language of Dart that lets you save and sync your application data offline.

As a key-value storage device created in Dart, Hive supports primitive and intricate data structures while delivering the highest degree of performance. Furthermore, it is secured with AES-256.

To illustrate Here is the graph below that compares Flutter Hive to other similar databases:

Getting Started with Handle Offline Data Storage with Flutter Hive

In this blog post, we’ll examine how to utilize the TypeAdapter in Flutter with the Hive DataBase. Additionally, we’ll create a simple one-page application that displays a user overview, allows you to add new users, update current ones, and remove users.

How to use Flutter Hive to Handle Offline Data Storage?

Step 1: Dependency installation

Two prerequisites are needed before we can utilize Hive.

                      
                        hive and hive_flutter
                       You need to add the Hive and hive_flutter packages to pubspec.yaml as follows:
                        dependencies:
                         Flutter:
                               sdk: flutter
                         hive: ^2.2.3
                         hive_flutter: ^1.1.0
                          Add the dev dependencies
                        dev_dependencies:
                         flutter_test:
                           sdk: flutter
                        hive_generator: ^1.1.3
                        build_runner: ^2.2.0
                      
                        

Step 2: ​​Initialization Hive Database

The first step is to initialize Hive prior to calling runApp in the Flutter app.

                      
                         void main() async{
                        WidgetsFlutterBinding.ensureInitialized();
                          // Initializes Hive with a valid directory in your app files
                        await Hive.initFlutter();
                        runApp(const MyApp());
                       }
                      
                       

The initFlutter() function is provided by Hive.Basically, it initializes Hive by using the path returned by getApplicationDocumentsDirectory

Profit from the benefits of Hivean easy key-value database that stores information locally. You will immediately see the benefits over Sqlite because Hive lets you modify the data on the devices you want to use it. Hire Flutter Developer

Box in Hive

Here’s how you can deal with offline data storage using Flutter Hive.

The data that is stored within Flutter Hive are arranged into boxes. The box is akin to the table that is used in SQL but does not have a structure and is able to contain everything. As I explained in my introduction Hive secures data.Additionally these boxes are able to be used to store sensitive data.

Utilizing key-value sets, Hive keeps its information. The first step is to open the box.

                      
                        void main() async{
                        WidgetsFlutterBinding.ensureInitialized();
                       // Initializes Hive with a valid directory in your app files
                        await Hive.initFlutter();
                       // open box
                       await Hive.openBox("userBox");
                       runApp(const MyApp());
                       }
                      
                       

Model class with TypeAdapter

Our example contains several users with information such as name, hobby, and description.

                      

                      import 'package:hive/hive.dart';

                        part 'user_model.g.dart';
                        
                        @HiveType(typeId: 0)
                        class UserModel extends HiveObject {
                        @HiveField(0)
                         final String name;
                         @HiveField(1)
                         final String hobby;
                         @HiveField(2)
                         final String description;
                        
                         UserModel({
                        required this.name,
                        required this.hobby,
                         required this.description,
                        });
                        }
                      
                        

The first step is to import the hive generator package. In order to generate the type adapter, add a section called user_model.g.dart.TypeAdapter does not need to be constructed manually since we are using the hive generator package.

It automatically builds TypeAdapters for virtually any class by using the hive_generator software pack You can observe that the userModel class has been notated with a variety of fields

@HiveType(): Use @HiveType() to make the model class obvious so the generator knows that this is supposed to be a TypeAdapter.

@HiveField(index): Notifying the fields of the class by a field with the associated index is required.

To construct a TypeAdapter class, run the following command. flutter packages pub run build_runner build

This file’s name is user_model.dart and the data_model.g.dart files will also be included, where the word “g” stands for generated. This means that user_model.g.dart is the new generated file.

It’s time to sign up for UserModelAdapter as it’s been successfully built

To achieve this, we have to create that adapter before running the app’s run function.

                      

                      void main() async{
                        WidgetsFlutterBinding.ensureInitialized();
                       // Initializes Hive with a valid directory in your app files
                        await Hive.initFlutter();
                       // Register Hive Adapter
                       Hive.registerAdapter(UserModelAdapter());
                       // open box
                       await Hive.openBox("userBox");
                       runApp(const MyApp());
                       }
                      
                       

CRUD operations

Creating Data in Hive

You can use the reference to the Hive box to add data by calling add() function.A key-value pair is accepted by this method.

                      

                      /// Add new user
                            Future addUser({required UserModel userModel}) async {
                             await box.add(userModel);
                            }
                          
                            

The dialog will appear when we press the floating button. Here, you can type in names, hobbies and descriptions. Following that, we click the add button and then the information will show.

The ValuelistenableBuilder() stream in Flutter Hive can also be used to listen to what is happening inside the box.

Retrieving Data in Hive

Box objects can be read by using the get() method. To retrieve its value, you simply need to provide the key, like this

                      

                     
                            var userHobby = box.get('hobby');
    
    In case you are using auto-incrementing values, you can use the getAt(index) method of the box object to read using the index,like this
    
    
    var userData = box.getAt(index);
    ValueListenableBuilder(
     valueListenable: HiveDataStore.box.listenable(),
       builder: (context, Box box, widget) {
       return SafeArea(
           child: box.length > 0 ? ListView.builder(
               shrinkWrap: true,
               itemCount: box.length,
               itemBuilder: (BuildContext context, int index) {
                 var userData = box.getAt(index);
                 return Container(
                   padding: const EdgeInsets.all(10),
                   margin: const EdgeInsets.all(10),
                   decoration: BoxDecoration(color: Colors.grey.withOpacity(0.1),

The put() method can update the data you originally stored for a key.In this way, the newly provided value will be updated at that key.

                      

                      /// update user data
                            Future updateUser({required int index,required UserModel userModel}) async {
                             await box.putAt(index,userModel);
                            }
                          
                            

Here we have used the auto-incrementing values, you can use the putAt(index) method of the box object to update using the index.

Deleting Data in Hive

                      

                      In order to delete data, you can pass the key to the delete() method.
                        /// delete user
                        Future deleteUser({required int index}) async {
                         await box.deleteAt(index);
                        }
                      
                        

Here we have used the auto-incrementing values, you can use the deleteAt(index) method of the box object to delete using the index.

LazyBox

Each time we design the regular box, the contents are recorded in memory.Performance is higher as a result.

The LazyBox is a fantastic way to quickly access data when you have a lot of data within an archive and don’t wish to put it all in memory.

                      

                     var lazyBox = await Hive.openLazyBox('myLazyBox');
                     var value = await lazyBox.get('lazyVal');
                          
                            

Box Compression

We have now completed most of the coding for the app. It’s time to clean up: the Hive is an append-only store.It is possible to manually use the .compact() method or let Hive handle it for us.

As a result, I have overridden the dispose method in order to close the Openbox.

                      
                        @override
                        void dispose(){
                           // to free up space 
                          Hive.box('userBox').compact();
                          // close all the open boxes before closing the page.
                          Hive.close();
                        }
                      
                        

Frequently Asked Questions (FAQs)

Hive is a lightweight and fast key-value database written in Dart, specifically designed for Flutter applications. It is used for offline data storage in Flutter apps to persist data locally on the device, allowing users to access and manipulate data even when they are offline.
Unlike other offline data storage solutions in Flutter, such as SQLite or SharedPreferences, Hive offers a simpler and more efficient approach to data storage with its key-value database model. It provides faster read and write operations, support for complex data structures, and seamless integration with Flutter widgets.
Hive offers several key features for offline data storage, including fast read and write operations, support for encryption and compression, lazy loading of data, efficient memory management, type safety, and easy integration with Flutter’s reactive framework.
Setting up Hive for offline data storage in a Flutter app involves adding the Hive package to the project dependencies, initializing Hive in the main application class, defining Hive boxes to store data models, and configuring adapters for serializing and deserializing complex objects.
Hive supports storing various types of data, including primitive types (int, double, string, bool), lists, maps, custom objects, and enum types. It also provides support for type-safe queries and efficient data retrieval using indexes.
Hive does not handle data synchronization or conflict resolution in offline mode by default. It is up to the developer to implement strategies for handling conflicts, such as optimistic locking, manual conflict resolution, or data merge algorithms, depending on the application’s requirements.
Best practices for using Hive include defining clear data models with appropriate fields and data types, minimizing the size of stored data, using efficient data retrieval techniques (e.g., lazy loading), handling errors and exceptions gracefully, and periodically optimizing and compacting Hive databases.
Hive ensures data integrity and durability by employing ACID (Atomicity, Consistency, Isolation, Durability) properties, using transactional write operations, maintaining backup copies of database files, and providing error handling mechanisms for handling data corruption and recovery.
Common pitfalls include overusing Hive boxes and keys, storing large amounts of data inefficiently, failing to handle exceptions and errors properly, not properly managing Hive database instances and closures, and neglecting to implement data encryption for sensitive information.
Developers can find additional resources and tutorials on official Hive documentation, Flutter community forums like Stack Overflow and Reddit, Flutter development blogs and YouTube channels, online courses and tutorials, and GitHub repositories with sample projects and code examples. Additionally, exploring the source code of the Hive package itself can provide insights into its implementation and usage.

A Step-By-Step Guide to Building Real-time Apps With Flutter and WebSockets

Introduction

Have you ever considered the key role of fast app development and real-time features? These are crucial for today’s apps. Many applications rely on the capabilities of real-time. They include messaging, sync stock market prices and providing live notifications. To meet these needs, REST on its own requires many calls to one endpoint. This can be a burden on the server. They have solutions. They allow seamless communication between client and server.

What are Web Sockets

Web sockets are a protocol for communication. They enable real-time, full-duplex communication between a client and server. This happens via an extended, continuous connection. HTTP follows an order-response model. But, Web Socket lets the server and client start data transmission. It lets them create a permanent connection. This connection stays open until shut. This means that both server and client can talk with each other at any point. This gives an uninterrupted, real-time experience.

What are WebSockets Used For?

Web socketsWeb Sockets begin continuous, two-way communication. It is between your client and Web Socket server. This eliminates traffic. A single connection can send data. It gives speed and real-time experience on the internet. Web Sockets let servers track clients. They can send them info when needed. HTTP can’t do this. Web Sockets have many uses. They are vital for real-time communications. For example:

  • Chat Applications
  • Multiplayer Online Games
  • Financial Trading Platforms
  • Live Sports Updates
  • Live Collaboration Tools
  • Real-time Monitoring and Tracking Systems

Support For WebSockets using Flutter

Flutter provides extensive support for Web Sockets using WebSocketIO class. It is important to keep in mind that the class depends on ‘dart.io and ‘dart:html. We can’t build for mobile and web at the same time. Dart’s team has come up with the ‘web_socket_channel’ to address this issue. It integrates both libraries so that they can work well on cross-platform development.

Setting up the Dart Server project

Let’s begin by creating the new Dart SDK. First, ensure that you are running the most recent version of Dart SDK in place. In your terminal, run these commands:

dart create -t server-shelf web_socket_server
cd web_socket_server

Creating WebSocket Server to listen to websocket IO request

Let’s begin by studying the Dart server’s code, which is capable of continuously monitoring WebSocket IO requests directed towards it, and ensuring an efficient handling of these requests.

                        
                            void main(List args) async {
                                // Use any available host or container IP (usually `0.0.0.0`).
                                var server = await HttpServer.bind(InternetAddress.anyIPv4, 8080);
                                print('WebSocket server listening on ${server.address}:${server.port}');
                               
                                await for (var request in server) {
                                 //receive the websocket request
                                 WebSocketTransformer.upgrade(request).then(
                                  (webSocket) async {
                                   print('Client connected');
                                  },
                                 );
                                }
                               }
                               
                        
                    

Let’s then add technology to send information via our servers to the client. In Particular, we’ll send prices for various cryptocurrency coins to the client to check. The prices update every second. This allows for real-time testing of our client connection. A function generates random prices for five coins. The prices range between 100 to 200.

                            
                                List> generateRandomPrices() {
                                    final List cryptocurrencies = [
                                     'Bitcoin',
                                     'Ethereum',
                                     'Ripple',
                                     'Litecoin',
                                     'Cardano'
                                    ];
                                    final Random random = Random();
                                   
                                    List> prices = cryptocurrencies.map(
                                     (crypto) {
                                      // Random price between 100 and 200
                                      double price = 100.0 + random.nextDouble() * 100.0;
                                      return {
                                       'name': crypto,
                                       'symbol': crypto.substring(0, 3),
                                       'price': price.toStringAsFixed(2)
                                      };
                                     },
                                    ).toList();
                                   
                                    return prices;
                                   }
                                   
                            
                        

We also added a more delay of 3 seconds in the initial request to control the loading behavior . To launch the dart server start by running the following command from your terminal:

                        
                            WebSocketTransformer.upgrade(request).then(
   (webSocket) async {
    print('Client connected');
    // Fetch initial cryptocurrency prices with a delay of 3 seconds to show loading
    await Future.delayed(
     Duration(seconds: 3),
    );
    List> initialPrices = generateRandomPrices();
    webSocket.add(
     json_Encode(initialPrices),
    );
    // Set up a timer to update prices every second
    Timer.periodic(
     Duration(seconds: 1),
     (timer) {
      List> updatedPrices =  generateRandomPrices();
      webSocket.add(
       json_Encode(updatedPrices),
      );
     },
    );
    webSocket.listen(
     (data) {
      // You can add custom logic for handling client messages here
      print('Received data: $data');
     },
     onDone: () {
      print('Client disconnected');
     },
    );
   },
  )

                        
                    

Setting up the Flutter project

To start the creation of a brand new Flutter project, it’s essential to have the latest Flutter SDK in place. Go to your terminal, and then execute the following commands:

flutter create web_socket_client
cd web_socket_client

Adding WebSocket IO Dependencies

To use websockets within Dart we need to integrate websockets and the web_socket_channel package into our Dart project. Browse through the ‘pubspec.yaml’ file in your program’s source. Make sure to incorporate the following line:

dependencies:
web_socket_channel: ^2.4.0
Be sure to run the command “flutter pub get” in your console. This will get and install the latest dependencies.

Connecting to a WebSocket

Once we finish setting up the project, we can make a simple application. It will connect to a Web Socket channel.

                        
                            import 'package:flutter/material.dart';
import 'package:web_socket_channel/web_socket_channel.dart';

void main() => runApp(WebSocketApp());

class WebSocketApp extends StatelessWidget {
 final WebSocketChannel channel = WebSocketChannel.connect(
  Uri.parse('ws://192.168.3.243:8080'),
 );

 WebSocketApp({super.key});

 @override
 Widget build(BuildContext context) {
  return MaterialApp(
   home: Scaffold(
    appBar: AppBar(
     title: const Text('Crypto Tracker'),
    ),
    body: Container(),
   ),
  );

                        
                    

Web Socket URLs generally start by a “ws:” or “wss:”. We’re now ready to use the new data. It is connected through Web Socket. Have you considered how to show and update the data? New information will come from the servers.

To solve this issue, we’ll make use of Flutter’s inbuilt Stream Builder widget. The widget can refresh data when it spots new information in this data stream. Web Socket uses an info stream. It allows the exchange of info in both directions. This is vital for real-time apps.

Building a Real-Time Feature

                    
                        Now, we are building the StreamBuilder widget. It will receive the information from our Websocket and show it.

import 'dart:convert';
import 'dart:io';

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:web_socket_channel/web_socket_channel.dart';

void main() => runApp(WebSocketApp());

class WebSocketApp extends StatelessWidget {
 final WebSocketChannel channel = WebSocketChannel.connect(
  // here the url can be replaced with your own websocket url
  Uri.parse('ws://192.168.3.243:8080'),
 );

 WebSocketApp({super.key});

 @override
 Widget build(BuildContext context) {
  return MaterialApp(
   home: Scaffold(
    appBar: AppBar(
     title: const Text('Crypto Tracker'),
    ),
    body: StreamBuilder(
     stream: channel.stream,
     builder: (context, snapshot) {
      if (snapshot.hasData) {
       List body = json_Decode(snapshot.data);
       return ListView.builder(
        shrinkWrap: true,
        itemCount: body.length,
        itemBuilder: (context, index) => ListTile(
         leading: Text(
          body[index]["symbol"],
         ),
         title: Text(
          body[index]["name"],
         ),
         trailing: Text(
          '₹${body[index]["price"]}',
         ),
        ),
       );
      } else if (snapshot.hasError) {
       return Center(
        child: Text(
         'Error Connecting : ${snapshot.error.toString()}',
        ),
       );
      } else {
       return Center(
        child: Platform.isIOS
          ? const CupertinoActivityIndicator()
          : const CircularProgressIndicator(),
       );
      }
     },
    ),
   ),
  );
 }
}

                    
                

The app is a simple one that connects to the WebSocket by using the StreamBuilder widget. It then shows the data received via the web server.

Introduction

Flutter is famous because of its significant features. These include hot reload, high-performance widgets, and a dazzling visual interface. It is not famous because it’s open-source or made by Google. Flutter’s features empower developers. They can use them to make great cross-platform apps. The apps have top visuals and great performance.

According to Statista, 46 percent of developers use Flutter. They use it to make cross-platform applications. Flutter is popular. This is not an illusion. Impressive evidence and interesting data support it. We’ll discuss them in the coming weeks. Since 2017, Google has used Flutter. The developer community has since tripled. As of now over 4 million developers around the world use Flutter.

What is Flutter?

Flutter is a front-end framework created by Google. It is open-source and a flexible tool for making apps. It receives acclaim for its compatibility with iOS and Android. This makes it a favorite among developers. Google created the object-oriented programming language Dart, which utilizes Flutter.

What sets Flutter apart is its ability to build apps for many platforms. These include iOS, Android, and even web browsers like Fuchsia, Linux, Windows, and macOS. You can do this all with a single codebase.

It launched in 2015. But, Flutter stayed in Beta until the year. Then, Flutter introduced it as Flutter 1.0. The release also introduced Dart as its programming language. Since then, Flutter has undergone advancements. It has grown in acceptance across the globe. A study among programmers found that 35% of them use Flutter at the start. 26% use it for business applications.

Flutter includes two crucial components:

1. Software Development Kit (SDK):

It comes with Dart, the object-oriented programming language. It also includes rendering tools, command line tools, and widgets. SDK prioritizes user interfaces.

2. Framework:

determines your program’s architecture and structure. It also affects your user’s interface. Managing state and routing are vital to using the Flutter framework. Pre-build and state management widgets are also critical. All in all, it’s an integrated framework. It includes a set of customizable widgets that meet specific requirements.

The best part is that Google keeps investing in Flutter. They do it to ensure Flutter’s long-term viability. They are always adding the latest updates. This makes Flutter a vital tool for developers. It’s for those who want to build great applications. This gives credibility and confidence to business owners as the most forward-looking framework. According to Statista, Flutter took over React Native in 2022. It became the top framework for cross-platform mobile app development.

Top 8 Benefits of Flutter to Empower Your Business

Flutter has unique advantages. It has them when compared with other cross-platform and native platforms. Here’s a list of big advantages of Flutter. They will help you run your business well and fast.

High Performance

Flutter has one code base. It offers native-like app performance. This improves the app’s functionality, productivity, and stability. It aims to offer sixty frames per second (fps) or 120 frames per second. This suggests higher mobile responsiveness.

Additionally, Flutter compiles the code into ARM machine code. This makes the UI rendering more efficient. Also, using ready-made widgets and a strong ecosystem allows smooth animations. It also allows for faster response.

Customizable UI

We need a framework that can provide seamless user interfaces. It must work for any type of application. Flutter is the solution. Flutter provides good UI widgets. They are custom and high quality. They let you make attractive user interfaces. It includes pre-built widgets. They have switches, text fields, and buttons. The widgets work on iOS and Android.

The main benefit of customizing is the ability to change the look of your app in real-time. You can also control the look and feel of the user interface. Also, changing screen size performance and user experience are easier in Flutter. This is true regardless of complexity, because of the flexible UI.

Cross-platform Support

One of the most important factors in deciding on Flutter is the cross-platform compatibility. Flutter is a platform that uses the Dart programming language that permits users to use the same code on iOS as well as Android platforms. This means that it is not necessary to make even small code modifications when using different platforms.

Additionally, using one codebase and a customized widget, developers gain the ability to alter and control the app’s appearance and feel, as well as performance. Additionally, it increases the possibilities of combining regarding the performance of an application.The main benefit of customizing is the ability to change the look of your app in real-time. You can also control the look and feel of the user interface. Also, changing screen size performance and user experience are easier in Flutter. This is true regardless of complexity, because of the flexible UI.

Improved Render Engine

Flutter comes with a render engine called Skia. Skia does not need platform-specific UI components to make animations and graphics. If the app is large and complex, Flutter ensures it is pleasing. It also runs with little resource use. This means you can design appealing visualizations for Android or iOS. They include vivid colors on iOS and pixel-rich images on Android.

Additionally, you can apply the material design of Android and the user interaction of iOS. Additionally to that, using Flutter the application can incorporate stunning displays and high-resolution images in your application, improving user experience and interfaces.
