MenuButtonThemeData class
A ButtonStyle theme that overrides the default appearance of SubmenuButtons and MenuItemButtons.
Descendant widgets obtain the current MenuButtonThemeData object using MenuButtonTheme.of.
A MenuButtonThemeData is often specified as part of the overall Theme with ThemeData.menuButtonTheme.
The style's properties override MenuItemButton's and SubmenuButton's default style, i.e. the ButtonStyle returned by MenuItemButton.defaultStyleOf and SubmenuButton.defaultStyleOf. Only the style's non-null property values or resolved non-null WidgetStateProperty values are used.
