GestureTapUpCallback? onSecondaryTapUp
read / write

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

This triggers on the up event if the recognizer wins the arena with it or has previously won.

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