Why Use Flutter For Embedded Systems?

Introduction

Dart is a cross-platform language. Dart is the basis for Flutter. It has become more important in recent years. It’s not mature or old enough to be in the market. But, it’s the sixth most-loved framework for product managers. This is in the Stack Overflow Developer Survey 2022. Because of its cross-platform compatibility. Flutter Embedded is gaining popularity in another area. Even new product owners and big brands are switching to Flutter. They use it for their product development. Before you dive into Flutter Embedded, ask yourself: “What are Embedded systems?””

What are Embedded Systems?

Embedded Systems combine software and hardware. They work together to do a specific task. The task can exist alone or be part of a larger system with a microprocessor or microcontroller. These systems also have an integrated circuit. It is designed to run computations in real time.

They may also have many complexities. These range from a microcontroller up to an array of processors. They have connected networks and peripherals. They also range from a non-user interface to sophisticated GUIs. But, the level of complexity is correlated to the difficulty of the job that it was designed for. At present, approximately 98% of microprocessors used are embedded systems.

Characteristics of Embedded Systems

Why Use Flutter Embedded Systems?

Technology Flutter has experienced a major rise in its popularity for Embedded Systems. But, the market isn’t sure. It’s unclear if Flutter is right for your business’s needs. Well! The answer to this question is in the features of Flutter. What makes it a front-row player is its cross-platform development. It lets you use a single code base on various platforms. This saves time as well as money.

We are now familiar with the capabilities and capabilities of Flutter Embedded Systems. Let’s take a look at the reasons Flutter for embedded Systems is a viable option:

Easy Embedder API with AGL

Any infotainment system that runs Automotive Grade Linux can use the technology. They can do this by integrating an API. The Flutter engine’s architecture is easy to embed. It fits many types of environments. You only need to cross-compile the engine. Then, you need to put it in an embedded system. Flutter applications can join in-vehicle systems via the Embedder API. All kinds of engineers can use it.

Flutter’s embedder API is still beginning. Yet, it offers many features. They let us use an attractive Flutter UI on many appliances. These include washing machines, smart refrigerators, and IoT devices.

Community Support for Ongoing Development

We can’t improve Flutter for embedded applications without its large, inclusive community. Developers take part in the Flutter open-source community. They do so because they see open-source software as an investment in user experience. They see it as an investment at any company.

The team behind flutter has added support for embedded systems. They did this over the last two years. These systems include the web, Linux, macOS, and Windows. It is evident that they have accomplished this through the help of an active community. The potential of embedded systems by flutter is awe-inspiring.

You can embed Flutter. Do this when you’ll use low-powered devices, like thermostats and smart-displays. You can also add Flutter to operating systems. You can add it to emerging mobile platforms. Our assertion is that Flutter is the technology stack for your Embedded Systems. If it does not convince you, we can turn to market giants like TOYOTA and BMW. They agree with our claim. They can explain how they partnered with Flutter. It was to support their Embedded Systems.

Why Did Toyota Choose Flutter Embedded?

Toyota as we all know is a firm which values its customers. They work to enhance their experience through the time that the screens are on the dashboard. Toyota develops their own in-car technology. This is why Flutter intrigued them. They were thrilled about how Flutter could enhance their customers’ experience.

The level of excitement for Toyota increased with Flutter that supports embedded devices. Toyota offered to form the possibility of partnering with Flutter. Customers of Toyota are also connected to the business. They expect the same performance from their infotainment systems. This includes more fun driving and a screen that mimics Toyota’s style and experience.

Team members at Toyota found more confidence in choosing to use Flutter. They liked its powerful rendering engine and AOT compiling. These features let the team create a sleek look and feel like a smartphone app. This was unlike the more traditional look of an embedded system. Let’s look at the other factors that led TOYOTA to select Flutter:

Outstanding Performance with Toyota’s Reliability and Consistency

Toyota customers want an in-car user experience that is reliable and efficient. It must be in line with Toyota’s high-end standard. Flutter’s rendering engine works well in a small environment. Features like AOT compilation give us the stability we want in-vehicle tech.

Touch Mechanics Smartphones

In the realm of technology in cars. Toyota’s team can make the car user experience like that from smartphones. They can do this because of Flutter. Everyone can recall a bad touch screen app. It wasn’t on their phone. The apps often feel like they’re not comfortable. Utilizing Flutter’s cross-platform technology, the work Toyota is doing addresses that problem. Flutter has done an excellent job in packing touch mechanics. They made them appear natural.

Ergonomics for Developers

Flutter’s experience with development convinced users to use it. They learned about its capabilities. They use all Flutter’s platforms to help from idea to publication. But, they release their apps on one platform. Desktop support, along with hot reload, speeds development. It is in beta. Flutter supports many release targets, including iOS and Android tablets. This allows users to do physical and virtual testing. Flutter helps them improve their feedback process. They can use web support to integrate with design tools.

Quicker Iteration Customer Input

The Toyota team’s goal is to use Flutter to speed up software development. They are making software for in-vehicle use to improve customer service. Technology allows for high productivity and has a low entry barrier. This lets them create tighter feedback loops in their engineering and design processes. They can collect customer feedback more often. This is thanks to the faster iteration cycles. This helps Toyota in delivering its customers the most enjoyable experience possible.

BMW Also Chose Flutter

BMW is a famous car brand. It has embraced Flutter and launched a key interface. It connects the smartphone and a car. They launched it in a variety of countries and plan to launch it in a variety of other countries. But, a scalable software structure works everywhere. It drives the rapid growth of the My BMW app’s content. It also drives the rapid deployment.

BMW did the whole development process in-house. They used Flutter and Flutter together. This gave a better user experience and access to more features worldwide. The application involved Amazon Alexa integration in BMWs with 7.0 Operating Systems. It also worked with Voice Service for BMWs with 5.0 or 6.0 Operating Systems.

How To Run A Flutter Application On Different Devices?

As we’ve discussed before, Flutter’s wide multi-platform capabilities make it ideal for developers. They can fine-tune the hardware and software of the latest solutions.

Consider the community support you get from the Flutter fans. It will help you design amazing Flutter Embedded solutions.

Flutter Web Support

A typical Web UI can be designed using Dart and then translated into JavaScript code. The JavaScript code is able to be installed as a standard web frontend and linked to the backend of your choice. The UI is rendered using the browser technology rendering instead of native rendering.

FlutterEmbedded Systems Support

It is the simplest method to use Flutter front-end applications for embedded systems. They develop the front-end in Dart instead of relying on browser technology. It is then converted into native code, such as (Java, Kotlin, C++, Swift, etc.). The converted code runs as a native program with a native graphics engine.

How Does the Flutter Application Communicate with the UI, Especially in Embedded?

As we’ve mentioned, Flutter’s broad multi-platform capabilities are a great option for developers. They can tweak the hardware and software of the latest devices.

Look at the help you can get from the Flutter fans. They can help you make great Flutter Embedded Solutions.

The Flutter app on the device needs an interface. It transfers gestures from the screen to the app. And, it transfers gestures from the users’ interfaces to the user interface. There are only a few primary display server protocols that come with this feature. Wayland is the latest technology. X11 is the more traditional technology. Flutter needs both protocols. It needs them to handle the most popular embedded Linux distributions. It also needs them for the limits of server development.

Alternatives to Flutter for Embedded

Flutter is not experienced in this Embedded Systems segment. It needs to be more advanced than other options. Here are two options for Flutter’s Embedded System. And, here is a simple study comparing them to Flutter.

Chromium Kiosk

You can use Chromium Kiosk mode and the Electron application on embedded platforms. Both platforms allow users to use popular internet techniques. They use HTML, JS, and CSS to create web applications. This is true despite their differing configurations. The downside is that running them requires a lot of overhead. This overhead could slow your application. As an example, for instance, you need to run all desktop Linux to run Chromium. Chromium web browser while in kiosk mode.

The app then runs within the browser, rather than running “bare metal” Linux with Flutter-Pi. The inability to talk to the platform and external devices is another problem. JavaScript was never designed to handle such tasks. So, it must bridge to talk to the Bluetooth module. The primary characteristic that makes it superior to Flutter embedded Systems is maturity.

Qt

The next step follows Qt. Although Qt is more focused on desktops or embedded systems, Qt operates like Flutter. It is possible to create Qt apps using C++, a not-as-well-known primary language. Qt is better integrated with platforms. This makes communication with them and external devices easier. C++ forms the foundation of Qt. It has more libraries than Flutter. It is also more mature. As we all know, C++ is faster than Dart and other languages. This gives Qt an edge over Flutter for Embedded development. The only disadvantage to Qt is that it’s not completely free.

The Future of Flutter Embedded Systems

Flutter was only available only for Android as well as iOS. In the following months, the Flutter team also added the ability to run on desktop OSes. These include macOS, Windows, and Linux. Also, the capability to build web applications was also added. This shows that they intend to offer a wide range of streams soon. Soon, Google will make public its commitment to Flutter for years. It will do this by releasing Flutter 4.0.

More platforms are available for Flutter development. They grow as its capabilities and productivity increase. Soon, developers will keep using Flutter. They will use it to develop apps for any platform, app, or market.

The official document says they don’t allow custom engine embedders. They can’t fix the issues listed on their websites. The updates for the engine embedder will likely be slower than those for Dart and Flutter. This is due to the high maintenance burden for the Flutter team.
