FloatingActionButtonThemeData class Null safety

Defines default property values for descendant FloatingActionButton widgets.

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

Typically a FloatingActionButtonThemeData is specified as part of the overall Theme with ThemeData.floatingActionButtonTheme.

All FloatingActionButtonThemeData properties are null by default. When null, the FloatingActionButton will use the values from ThemeData if they exist, otherwise it will provide its own defaults.
