When the scrollbar is interactive, the associated ScrollController must only have one ScrollPosition attached.The provided ScrollController must be unique to one ScrollView widget.' has been skipped to due to duplication occurence within 3000 ms.Example code (optional)

hello， you can set scrollerController to CustomScrollView，like this： @override Widget build(BuildContext context) { super.build(context); return CustomScrollView( physics: scrollingPhysics(), controller: ScrollController(), //add this slivers: [ ..... ], ); }
