InputOverlay class
Builds GestureDetector
s for each square on the board, handling some
common gestures such as right clicks, long presses etc. Doesn't include
everything that GestureDetector
supports because it has literally 60+
parameters. It's easy enough to add more if you need them, and if you think
one is a common enough use case, feel free to make a PR.
Note that this can't support onTap
because it will interfere with the
standard piece drag behaviour. Also note that gestures like long press
will make tap responses on the pieces and squares take longer to respond
as the gestures have to go through this first.
