Flutter

Builds, debugs, and ships Flutter apps: widgets, layout constraints, state management, navigation, performance, and store releases. Use when writing Dart widgets or screens; when a RenderFlex overflows, a viewport is given unbounded height, or a RenderBox was not laid out; when setState is called during build or after dispose, or BuildContext is used across an async gap; when the UI janks, scrolling stutters, or images exhaust memory; when hot reload stops applying changes; when Provider, Riverpod, or Bloc rebuild too much or too little; when routing with Navigator or go_router, deep links, or back-button handling; when the keyboard covers a form field or validation misfires; when a platform channel throws MissingPluginException; when localizing strings or mirroring a layout for right-to-left; when widget, golden, or integration tests hang or fail in CI; or when a build works in debug but the release APK, IPA, or web bundle breaks. Not for React Native or native-only Swift and Kotlin work.
