Swipeable stack is not working when you call setState inside onSwipeCompleted or onWillMoveNext

[jiseeeh]

When I call setState inside those callbacks, the next time you swipe won't work.

I found a solution for that, i added a ValueNotifier for index, then listen SwipeableStack current index from ValueNotifier then call setstate from there.

  ValueNotifier<int> pageIndex = ValueNotifier<int>(0);


  @override
  void initState() {
    super.initState();
    pageIndex.addListener(() {
      int leftCards = cards.length - pageIndex.value;
      if (leftCards < 5) {
        print('fetching moooooreeee');
        fetchMore();
        setState(() {});
      }
    });
  }
  
  
    SwipableStack(
              onSwipeCompleted: (index, direction) {
                pageIndex.value = index;

                if (direction == SwipeDirection.right) {
                  //handleInteraction(index, false);
                } else {
                  likeCountLeft--;
                  //handleInteraction(index, true);
                }
              },
             
            ),

            }
          },
         
        ),

This is not working for me pls

Can you share your code

This also happens when showModalBottomSheet is used for the card inside the swipeable stack. This causes the animation to fade away, however the onSwipe callback works
