GestureTapUpCallback? onTapUp
read / write

A pointer has stopped contacting the screen at a particular location, which is recognized as a tap of a primary button.

This triggers on the up event, if the recognizer wins the arena with it or has previously won, immediately followed by onTap.

If this recognizer doesn't win the arena, onTapCancel is called instead.
