BottomAppBarTheme class

Defines default property values for descendant BottomAppBar widgets.

Descendant widgets obtain the current BottomAppBarThemeData object using [BottomAppBarTheme.of]. Instances of BottomAppBarThemeData can be customized with BottomAppBarThemeData.copyWith.

Typically a BottomAppBarThemeData is specified as part of the overall Theme with ThemeData.bottomAppBarTheme.

All BottomAppBarTheme properties are null by default. When null, the BottomAppBar constructor provides defaults.

Constructors

BottomAppBarTheme.new({Key? key, Color? color, double? elevation, NotchedShape? shape, double? height, Color? surfaceTintColor, Color? shadowColor, EdgeInsetsGeometry? padding, BottomAppBarThemeData? data, Widget? child}): Creates a theme that can be used for ThemeData.bottomAppBarTheme.
