MenuBarTheme class
An inherited widget that defines the configuration for the MenuBar widgets in this widget's descendants.
This class defines the visual properties of MenuBar widgets themselves, but not their submenus. Those properties are defined by MenuTheme or MenuButtonTheme instead.
Values specified here are used for MenuBar's properties that are not given an explicit non-null value.
See also:
- MenuStyle, a configuration object that holds attributes of a menu, and is used by this theme to define those attributes.
- MenuTheme, which does the same thing for the menus created by a SubmenuButton or MenuAnchor.
- MenuButtonTheme, which does the same thing for the MenuItemButtons inside of the menus.
- SubmenuButton, a button that manages a submenu that uses these properties.
- MenuBar, a widget that creates a menu bar that can use SubmenuButtons.
