postAcceptSlopTolerance property
The maximum distance in logical pixels the gesture is allowed to drift after the gesture has been accepted.
Drifting past the allowed slop amount causes the gesture to stop tracking and signaling subsequent callbacks.
Can be null to indicate that the gesture can drift for any distance. Defaults to gestureSettings.touchSlop with a fallback of 18 logical pixels.
Implementation
double? get postAcceptSlopTolerance =>
_postAcceptSlopTolerance == _unsetTouchSlop ? _defaultTouchSlop : _postAcceptSlopTolerance;
