What’s next for Flutter

Setting out our vision at the Flutter Forward event in Nairobi

Four themes: Breakthrough graphics performance, seamless integration for web and mobile, early to new and emerging architectures, and a continued focus on developer experience.

Breakthrough graphics performance

Historically, cross-platform frameworks have required compromise on visuals, due to the challenges of creating an abstraction layer. Flutter has taken a different approach than most, with its own rendering layer that offers hardware-accelerated graphics and a consistent visual appearance on every device. Moving forward, we will invest in breakthrough graphics performance that extends Flutter’s existing strength in this area.

Impeller provides silky-smooth performance for demanding graphical apps like Wonderous, a beautiful app that takes you on a tour of the world’s wonders. Shown here: the latest version of Wonderous, which adapts its UI for different devices and form factors, available at https://wonderous.app.

Seamless integration for web and mobile

While you can write an app entirely using Flutter and Dart, almost any non-trivial project needs to connect with other code. On the web, Flutter may be used as an embedded component within a larger app; on mobile, apps may need to call system APIs or other code written in another language. Our second major theme of investment is therefore seamless integration for web and mobile.

With Element Embedding, you can embed Flutter into a <div> element and use CSS to style it.

Early to new and emerging architectures

Thanks to Dart’s broad support for a wide range of processor architectures, as well as its highly-optimized JavaScript compiler, Flutter can already run on a broad variety of devices and form factors. But with some exciting new options on the horizon, our third theme is bringing early support to new and emerging architectures.

Continued focus on developer experience

Foundational to everything we’ve described above is developer productivity, which has been a hallmark of Flutter since its inception, with features like stateful hot reload. Our fourth and final area of investment for the future is a continued focus on developer experience, across both Flutter and Dart.

Moving forward together

We hope you share our excitement about where we’re taking Flutter moving forward. We’re continuing to invest heavily in the core developer experience, while making some foundational improvements that pave the way for ourselves and others to build even more powerful experiences with Flutter.

Four themes for future work: breakthrough graphics performance (Impeller, shaders, 3D support); seamless integration for web and mobile (element embedding, JNIgen and FFIgen); early to new and emerging architectures (WebAssembly and RISC-V); and a continued focus on developer experience (Dart language features, sound null safety, Google News Toolkit and Wonderous).
