Hope this can work for you.
Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text('My form'), ), body: Padding( padding: const EdgeInsets.all(16.0), child: Scrollbar( child: SingleChildScrollView( child: DraggableScrollbar.rrect( controller: myScrollController, child: ListView.builder( controller: myScrollController, itemCount: 1, itemBuilder: (context, index) { return Form(); }, ), ), ), ), ), );}
