SystemContextMenuController class
Allows access to the system context menu.
The context menu is the menu that appears, for example, when doing text selection. Flutter typically draws this menu itself, but this class deals with the platform-rendered context menu.
Only one instance can be visible at a time. Calling show while the system context menu is already visible will hide it and show it again at the new Rect. An instance that is hidden is informed via onSystemHide.
Currently this system context menu is bound to text input. The buttons that are shown and the actions they perform are dependent on the currently active TextInputConnection. Using this without an active TextInputConnection is a noop.
Call dispose when no longer needed.
