The work on Impeller has led to significant improvements in rendering performance for mobile platforms, resulting in much smoother and more fluid experiences. The Wondrous project is another example of the Flutter team's commitment to enhancing performance across the board. These efforts have already produced great results, and the team continues to invest in further optimizations to ensure that Flutter apps run smoothly on all supported platforms.

Regarding the web, the primary focus of the Flutter team is on targeting WebAssembly (Wasm). Wasm is a compact binary format that allows code to run at near-native speed on the web. By supporting Wasm, the Flutter team aims to bring massive improvements to both the startup performance and runtime performance of Flutter apps on the web. This will enable developers to create web applications with Flutter that offer an even more seamless and responsive user experience.

Interoperability

Interoperability improvements in Flutter aim to make it easier for developers to integrate their apps with native platforms such as Android, iOS, and the web. By enhancing interoperability, the Flutter team seeks to reduce the friction involved in working with existing systems, platforms, and libraries, allowing developers to create seamless and high-quality applications that function smoothly across different environments. This interoperability was key to delivering the SeeChange IoT project on Flutter to Arm.

Android

For Android, the Flutter team is working on making it easier for apps to integrate seamlessly with the underlying operating system. This includes reducing the costs of calling Jetpack libraries, minimising memory buffer copies, and simplifying the process of embedding Flutter into existing Android projects.

iOS

For iOS, the team aims to improve their ability to stay up to date with the latest iOS releases, including updates to the Cupertino widget set, modernising the package ecosystem to use Swift Package Manager, and enhancing performance. They are also working on improving interop with Swift and Objective-C code through FFI

FFI has played a key role in helping Foresight deliver great value in SDK and integration projects for key customers such as Bandwidth and Flagsmith.

The Web

On the web, the Flutter team is addressing the 'uncanny valley' syndrome, where developers notice differences between Flutter and DOM-based content. They plan to support embedding Flutter into existing web projects through technologies like Web Components, modernize JavaScript interop libraries, and continue working on supporting Wasm, Web Workers, and WebGPU for a more cohesive web experience.

These interoperability improvements are shared across multiple parts of the project, including the Dart language, runtimes, libraries, the Flutter engine, the Flutter framework itself, and the package ecosystem.

Targeting the Web so easily is one of the core reasons we use Flutter here at Foresight, and has been key to the success of some of our multi-platform projects such as Ryze, where users are able to switch seamlessly between desktop and mobile.

Portability

Portability is a critical factor in the success of Flutter, as it enables developers to create applications that run efficiently across various platforms and devices. By offering support for multiple processor architectures and targeting emerging technologies such as WebAssembly (Wasm), the Flutter team will ensure that their framework remains versatile and adaptable, catering to the diverse needs of developers and users alike.

Improving Desktop Support

Support for different processor architectures is essential because it allows Flutter apps to run smoothly on a wide range of devices, from smartphones and tablets to desktop computers and embedded systems. As the technology landscape evolves, new processor architectures, such as ARM for desktop-class operating systems and RISC-V for embedded scenarios, are gaining prominence. The Flutter team's commitment to supporting these architectures ensures that developers can continue to create high-performance, cross-platform applications that meet the needs of a growing user base.

Turbocharging the Web

WebAssembly, in particular, holds significant potential for the future of web development, as it allows code to run at near-native speeds on the web. By targeting Wasm, the Flutter team aims to bring substantial improvements to the startup and runtime performance of Flutter apps on the web. This will enable developers to create web applications with Flutter that offer a more seamless and responsive user experience, rivalling traditional web development approaches.

A key advancement in WebAssembly is its support for garbage collected languages through WasmGC. This feature will enable languages like Dart, which rely on garbage collection, to run more efficiently within the WebAssembly environment. By embracing WasmGC, the Flutter team further enhances the performance and compatibility of Flutter apps on the web, making it an even more attractive choice for developers building cross-platform applications.

Ecosystem

The ecosystem surrounding Flutter is vital to the platform's success, as it provides developers with a comprehensive set of tools, libraries, and resources that support and enhance the development process. A thriving ecosystem attracts a diverse community of developers, fostering collaboration and innovation, while creating a robust foundation for building high-quality, cross-platform applications. 

By nurturing this ecosystem, the Flutter team ensures that the platform remains a compelling choice for developers, driving adoption and solidifying Flutter's position as a leading solution in the app development landscape.
