Chromium and V8 released stable support for WasmGC in Chromium 119. Note that Chrome on iOS uses WebKit, which doesn't yet support WasmGC. Firefox announced stable support for WasmGC in Firefox 120, but currently doesn't work due to a known limitation.
Flutter web WebAssembly uses multiple threads to render your application faster, with less jank. To do this, advanced browser features are used that require specific HTTP response headers.
Some earlier versions supported WasmGC with specific flags enabled, but WasmGC encodings changed once the feature was stabilized. To ensure compatibility, run the latest version of the Flutter main channel and the latest version of Chrome.
Flutter compiled to Wasm can't run on the iOS version of any browser. All browsers on iOS are required to use WebKit, and can't use their own browser engine.
