DoNothingAndStopPropagationIntent class Null safety

An Intent that is bound to a DoNothingAction, but, in addition to not performing an action, also stops the propagation of the key event bound to this intent to other key event handlers in the focus chain.

Attaching a DoNothingAndStopPropagationIntent to a Shortcuts.shortcuts mapping is one way to disable a keyboard shortcut defined by a widget higher in the widget hierarchy. In addition, the bound DoNothingAction will return false from DoNothingAction.consumesKey, causing the key bound to this intent to be passed on to the platform embedding as "not handled" with out passing it to other key handlers in the focus chain (e.g. parent Shortcuts widgets higher up in the chain).

This intent cannot be subclassed.
