PlatformProvidedMenuItem class Null safety

A class that represents a menu item that is provided by the platform.

This is used to add things like the "About" and "Quit" menu items to a platform menu.

The type enum determines which type of platform defined menu will be added.

This is most useful on a macOS platform where there are many different types of platform provided menu items in the standard menu setup.

In order to know if a PlatformProvidedMenuItem is available on a particular platform, call PlatformProvidedMenuItem.hasMenu.

If the platform does not support the given type, then the menu item will throw an ArgumentError when it is sent to the platform.

  • PlatformMenuBar which takes these items for inclusion in a platform-rendered menu bar.
