ButtonBarThemeData class
Defines the visual properties of ButtonBar widgets.

To obtain this configuration, use ButtonBarTheme.of to access the closest ancestor ButtonBarTheme of the current BuildContext.
See also:
- ButtonBarTheme, an InheritedWidget that propagates the theme down its subtree.
- ButtonBar, which uses this to configure itself and its children button widgets.
