Attention #

ExpandTapWidget can be wrapped inside/outside GestureDetector: To avoid the conflict of gesture, it is better to apply on the innermost/smallest widget.
The expanded area wouldn't exceed the boundary of the Parent Box. You can set debugPaintExpandAreaEnabled = true to display the actual expanded area.
