3.29.0
What's New
Flutter 3.29 delivers significant performance and platform interop improvements with Impeller reaching 100% Android device coverage and Dart execution moving to the main thread for synchronous platform calls. The release includes enhanced iOS fidelity with Cupertino updates, new Material 3 design patterns, and a redesigned DevTools inspector. Major breaking changes include removal of the web HTML renderer and iOS Skia support, plus discontinuation of six community packages.
Highlights
- Impeller now supports 100% of Android devices via OpenGLES fallback for non-Vulkan hardware
- Dart code executes on main thread on Android/iOS, enabling synchronous platform interop without serialization
- New Material 3 page transition builder with improved performance replaces ZoomPageTransitionsBuilder
- Cupertino navigation bars support bottom widgets with configurable scroll behavior and large title variant
- New DevTools inspector with condensed widget tree and automatic hot-reload updates enabled by default
- BackdropGroup and ImageFilter.shader optimize multiple backdrop filters and enable custom shader effects
- WebAssembly support relaxed to run with default HTTP headers, though limited to single thread

- Web image handling changed: webHtmlElementStrategy flag controls img element fallback behavior
Deprecations
