Sp3dGestureDetector({Key? key, required Widget child, void onPanDown(Sp3dGestureDetails details)?, void onSecondPanDown(Sp3dGestureDetails details)?, void onPanCancel()?, void onPanStart(Sp3dGestureDetails details)?, void onPanUpdate(Sp3dGestureDetails details)?, void onPanEnd(Sp3dGestureDetails details)?, void onPinchStart(Sp3dGestureDetails details)?, void onPinchUpdate(Sp3dGestureDetails details)?, void onPinchEnd(Sp3dGestureDetails details)?, void onScroll(Sp3dGestureDetails details)?, HitTestBehavior behavior = HitTestBehavior.opaque})
  • child : The child widget.
  • onPanDown : Callback at user touch initiation.
  • onSecondPanDown : Callback at user touch initiation of second finger.
  • onPanCancel : Callback at user touch cancel.
  • onPanStart : Callback at user pan start.
  • onPanUpdate : Callback at user pan update.
  • onPanEnd : Callback at user pan end.
  • onPinchStart : Callback at user pinch start.
  • onPinchUpdate : Callback at user pinch update.
  • onPinchEnd : Callback at user pinch end.
  • onScroll : Callback at user mouse scroll. This returns a diffV with the orientation stored in y. Any other value is zero.
  • behavior : Specification about the hit judgment area of the child widget.
    • const
