FloatingActionButtonThemeData class

Defines default property values for descendant FloatingActionButton widgets.

Descendant widgets obtain the current FloatingActionButtonThemeData object using FloatingActionButtonTheme.of. 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 provides its own defaults.
