I am working on chat application .. i need to scroll the list whenever a tagged message is clicked. I using the code below.

itemScrollController.jumpTo(index: index, alignment: 0.5);

Widget code follows ->

 `Widget build(BuildContext context) { 
 return ScrollablePositionedList.separated(
  padding: const EdgeInsets.only(left: 8, bottom: 14, top: 8, right: 8).w,
  key: ValueKey(conversation.id),
  itemScrollController: pagingController.itemScrollController,
  itemPositionsListener: pagingController.itemPositionsListener,
  physics: const ScrollPhysics(),
  reverse: true,
  itemCount: pagingController.itemsLength(),
  itemBuilder: _messageItem,
  separatorBuilder: (BuildContext context, int index) =>
      12.verticalSpaceFromWidth,
);
}`

Its seems like a random crash, any input would be appreciated here .. Let me know if you need more detail on the issue.. Thanks..
