GestureTapCallback? onTap

A tap with a primary button has occurred.

This triggers when the tap gesture wins. If the tap gesture did not win, onTapCancel is called instead.

  • kPrimaryButton, the button this callback responds to.
  • onTapUp, which is called at the same time but includes details regarding the pointer position.
