onExit property Null safety

  1. @override
PointerExitEventListener? onExit
final

Triggered when a mouse pointer, with or without buttons pressed, has exited the region and validForMouseTracker is true.

This callback is triggered when the pointer has stopped being contained by the region, either due to a pointer event, or due to the movement or disappearance of the region. This method always matches an earlier onEnter.
