Flutter, Dart, and WASM: Shipping a new model for Web applications by Kevin Moore @ Wasm I/O 2024

Kevin Moore explains how the Dart and Flutter teams compiled their garbage-collected languages to WebAssembly for high-performance web applications.

Wasm I/O 2024 / 14-15 March, Barcelona Slides: goo.gle/flutter-wasm-io-2024 Now that garbage collection is a standard feature in the WebAssembly runtimes in Chromium-based browsers and Firefox, there is an opportunity for a wide variety of existing GC-languages to target Wasm. Learn how the Dart and Flutter teams and Google worked to add support for this new language to our existing web support, while maintaining compatibility with existing JavaScript. Supporting compilation to both Wasm and Javascript was a challenge. We will cover how JS-interop and browser APIs evolved along with our support for multi-threaded rendering. We’re also excited to showcase our performance compared to JavaScript in the browser and even native code.
