BottomAppBarTheme class Null safety

Defines default property values for descendant BottomAppBar widgets.

Descendant widgets obtain the current BottomAppBarTheme object using BottomAppBarTheme.of(context). Instances of BottomAppBarTheme can be customized with BottomAppBarTheme.copyWith.

Typically a BottomAppBarTheme 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.
