GestureTapUpCallback? onSecondaryTapUp
final

A pointer that will trigger a tap with a secondary button has stopped contacting the screen at a particular location.

This triggers in the case of the tap gesture winning. If the tap gesture did not win, onSecondaryTapCancel is called instead.

See also:

  • onSecondaryTap, a handler triggered right after this one that doesn't pass any details about the tap.
  • kSecondaryButton, the button this callback responds to.
