![]() So why use Flutter in digital cockpits? There are lots of reasons: The need for modern development tools like Flutter arises from the fact that they empower developers to build high quality applications more effectively and efficiently, keeping up with the demands of the rapidly evolving software development landscape. In today’s fast paced and competitive software development landscape, features like automation tooling, faster iteration and rapid prototyping and experimentation also play a major role in addition to cross platform capability. It’s natural to question the need for a new framework when there is already a set of established tools.However when it comes to modern streamlined development requirements not all tools may meet the criteria. Any vulnerabilities in the framework are likely to be addressed quickly. Flutter also benefits from regular updates and contributions from a larger developer community. ![]() Using flutter also helps in managing security updates in multiple platforms easily. This helps to maintain an unified approach to security and reduces the risk of security vulnerabilities caused due to platform specific UI implementations. Flutter provides a consistent user interface framework across different platforms. ![]() This is why security is vital to designing in-vehicle interfaces. Security researchers have demonstrated that they can connect to a vehicle’s powertrain and other critical systems via the infotainment interface. So using flutter for such applications (like instrument cluster) might be difficult. Ensuring compatibility and optimal performance might require additional effort. The availability of community resources, documentation and libraries specifically tailored for Flutter on real time operating systems may be limited. So we just need to use flutter on top of our desired operating system and hardware platform by making use of custom embedders.However for safety critical applications like instrument cluster, real time operating systems are preferred. Custom embedders can be created based on the platform requirements. This includes the operating system, hardware platforms etc.ĭue to its layered architecture, the flutter applications can be easily ported to various platforms. In addition to application design and development, system architecture also plays an important role in ensuring safety. For example, as per the ISO 26262 Functional Safety Standard, the digital cockpit system should not cause any driver distraction and should always ensure the driver’s safety behind the wheels. While developing for the digital cockpit, there are specific safety and security standards that need to be followed. For example, custom embedders are available for devices like Raspberry Pi, developed by other communities such as Flutter-pi embedder and Sony-Flutter embedded. ![]() ![]() Flutter includes several embedders for common target platforms, but others also exist. The embedder is written in a language appropriate for the platform - Java and C++ for Android, Objective-C/Objective-C++ for iOS and macOS, and C++ for Windows and Linux.įlutter code can be embedded into an existing application as a module, or it can be the entire application content. A platform-specific embedder provides an entry point and coordinates with the operating system to gain access to services like rendering surfaces, accessibility and input. To the underlying operating system, Flutter applications are packaged in the same way as any other native application. ![]()
