ButtonBarThemeModifier class

Applies a button bar theme to descendant ButtonBar widgets.

A button bar theme describes the layout and properties for the buttons contained in a ButtonBar.

Descendant widgets obtain the current theme's ButtonBarTheme object using ButtonBarTheme.of. When a widget uses ButtonBarTheme.of, it is automatically rebuilt if the theme later changes.

A button bar theme can be specified as part of the overall Material theme using ThemeData.buttonBarTheme.
