AppBarThemeData class

Defines default property values for descendant AppBar widgets.

Descendant widgets obtain the current AppBarThemeData object using AppBarTheme.of. Instances of AppBarThemeData can be customized with AppBarThemeData.copyWith.

Typically an AppBarThemeData is specified as part of the overall Theme with ThemeData.appBarTheme.

All AppBarThemeData properties are null by default. When null, the AppBar will use the values from ThemeData if they exist, otherwise it will provide its own defaults. See the individual AppBar properties for details.

  • AppBar, which is the widget that this theme configures.
  • ThemeData, which describes the overall theme information for the application.
