FloatingActionButtonThemeData class
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.
