Flutter, Dart, and WASM-GC: A new model for Web applications
summary
Dart and Flutter compile the framework and app code to WebAssembly using WASM-GC, run Skia (CanvasKit) compiled from C++ to WASM for GPU-accelerated rendering, and replace JS shims with a linear-memory binding layer called squasm. Demo material3 apps and pixel shaders run in Chrome 111 with flags, showing startup improvements despite a compressed bundle growing from ~800 KB JS to ~1.2 MB WASM (≈30% larger) and preliminary speedups of ~1.5–3×; Firefox support awaits a tracked bug.
