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);
const Color lightGray = Color(0xFFFEFEFE);
const Text('This is a static text')

                            

Try Using Async/Await

It is crucial to ensure when developing to ensure that the code employed within the application is synchronous, or Asynchronous. By using Async/Await, code is written asynchronously within Flutter. Flutter application.

Async code is difficult to upgrade and troubleshooting the Asynchronous code can be difficult. But, code’s accessibility improves when it is paired with Async.

Develop And Display Frames

The display is split into two components of structure and picture. Developers can use 8ms for structure and another 8ms to render pictures to be rendered on 60hz displays.

Always split 16ms equally between image and structure to get better flutter performance for your application.

You might be thinking that the 16ms delay will affect the quality of the display? Do not worry about it, 16ms won’t affect any aspect of display quality. It will increase the battery’s lifespan. Additionally, by using 16ms you will get superior performance even on smaller devices.

Rebuilding Widget Animated Builder

Animation is among the most attractive aspects of any mobile or web-based application. It draws the attention of users however, at the same time, it affects the speed of the application.

The majority of developers employ AnimationController. It rebuilds several widgets inside AnimatedBuilder and this is one of the main reasons for slow Flutter performance.

To ensure that you do not have issues with performance To avoid performance issues, you can utilize CounterThe widget that allows you to build animations without having to rebuild multiple widgets.

Avoid Build Method

Beware of employing this Build() method since it’s expensive and uses up plenty of power. The repeated usage of Build() could affect Flutter’s performance. To maximize Flutter performance for your existing application, it is possible to break up the big widgets you created using the Building() process into smaller versions.

Decrease Application Size

In the early stages of development, it’s simple to integrate various codes, packages, and widgets to build an application. Sometimes, however, it will require massive storage to hold all the data, which in turn affects the application’s performance.

The development tool of Flutter has the benefit of reducing the application’s size. With Gradle’s help, you can decrease the size of your Flutter application for better performance.

With the packaging system that was introduced by Google with the packaging system, you can build bundles of Android apps. App Bundles can be beneficial in a variety of ways. One of the major benefits of an app bundle is that it permits you to download your own codes directly from the Google Play Store. Google Play Store provides applications compatible with the device, and also supports the platform’s design.
