MenuAcceleratorCallbackBinding class Null safety

An InheritedWidget that provides a descendant MenuAcceleratorLabel with the function to invoke when the accelerator is pressed.

This is used when creating your own custom menu item for use with MenuAnchor or MenuBar. Provided menu items such as MenuItemButton and SubmenuButton already supply this wrapper internally.
