onTapDown property

GestureTapDownCallback onTapDown
read / write

A pointer that might cause a tap has contacted the screen at a particular location.

This triggers before the gesture has won the arena, after a short timeout (deadline).

If the gesture doesn't win the arena, onTapCancel is called next. Otherwise, onTapUp is called next.
