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