Global styling and adaptive design patterns for Flutter apps using Material 3 theming. Flutter applies styling in a strict hierarchy: styles applied to the specific widget -> themes that override the immediate parent theme -> the main app theme. Material 3 is the default theme as of Flutter 3.16. Component themes in ThemeData have been normalized to use *ThemeData classes rather than *Theme widgets. When defining ThemeData , strictly use the *ThemeData suffix for the following properties: Legacy button classes ( FlatButton , RaisedButton , OutlineButton ) are obsolete. When building adaptive apps, respect platform-specific norms to reduce cognitive load and build user trust. Use this workflow when updating an older Flutter codebase. Task Progress: Use this workflow when building a widget intended for both mobile and desktop/web.
