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.
