Flutter applies styling in a strict hierarchy: styles applied to the specific widget -> themes that override the immediate parent theme -> the main app theme.
theme property of MaterialApp with a ThemeData instance.Theme widget and using Theme.of(context).copyWith(...).ThemeData properties:
accentColor with colorScheme.secondary.accentTextTheme with textTheme (using for contrast).colorScheme.onSecondaryAppBarTheme.color with AppBarTheme.backgroundColor.Material 3 is the default theme as of Flutter 3.16.
ColorScheme.fromSeed(seedColor: Colors.blue). This ensures accessible contrast ratios.ColorScheme.surfaceTint to indicate elevation instead of just drop shadows. To revert to M2 shadow behavior, set surfaceTint: Colors.transparent and define a shadowColor.letterSpacing on the specific TextStyle.BottomNavigationBar with NavigationBar.Drawer with NavigationDrawer.ToggleButtons with SegmentedButton.FilledButton for a high-emphasis button without the elevation of ElevatedButton.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:
cardTheme: Use CardThemeData (Not CardTheme)dialogTheme: Use DialogThemeData (Not DialogTheme)tabBarTheme: Use TabBarThemeData (Not TabBarTheme)appBarTheme: Use AppBarThemeData (Not AppBarTheme)bottomAppBarTheme: Use BottomAppBarThemeData (Not BottomAppBarTheme)inputDecorationTheme: Use InputDecorationThemeData (Not InputDecorationTheme)Legacy button classes (FlatButton, RaisedButton, OutlineButton) are obsolete.
TextButton, ElevatedButton, and OutlinedButton.ButtonStyle object.TextButton.styleFrom(foregroundColor: Colors.blue).MaterialStateProperty.resolveWith.When building adaptive apps, respect platform-specific norms to reduce cognitive load and build user trust.
thumbVisibility on the Scrollbar widget based on the platform.SelectableText or SelectableText.rich.Row with TextDirection.rtl for Windows and TextDirection.ltr for others.Tooltip for hover states and use context menu packages for right-click actions.Use this workflow when updating an older Flutter codebase.
Task Progress:
