onCancel property

GestureCancelCallback? onCancel
read / write

The pointer that previously triggered onTapDown did not complete.

This is called when a PointerCancelEvent is tracked when the onTapDown callback was previously called.

It may also be called if a PointerUpEvent is tracked after the pointer has moved past the tap tolerance but not past the drag tolerance, and the recognizer has not yet won the arena.
