Container(height: 100, child: Text('item 4')),
Container(height: 100, child: Text('item 5')),

Container(height: 100, child: Text('item 13')),
Container(height: 100, child: Text('item 14')),
Container(height: 100, child: Text('item 15')),

Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('title'),
),
body: ListView(
children: myTabs,

}
}Steps to Reproduce
- In iOS, turn on voice over.
- Scroll the list using three finger accessibility scroll.
Expect: The list scroll with an animation like a native UIScrollView.
Actual: The list just jump to the destination without any animation.
