[Android] Lists with AndroidOverscrollIndicator.stretch can be over scrolled infinitely with multi-touch #99264
Description
Steps to Reproduce:
- Use the Over-scroll behaviours on any scrollable widget.
scrollBehavior: MaterialScrollBehavior( androidOverscrollIndicator: AndroidOverscrollIndicator.stretch,), - Start scrolling normally, this works perfectly
- Now, over scroll the view, hold the finger and use another finger to over scroll.
Expectation :
You will be able to over scroll infinitely and you UI will get stretched without limits.
Expected results:
My assumption is the stretch over-scroll should not be triggered if the stretch is already implemented.
Actual results:
This is an example of live app google Pay having this issue
| Orignal UI | After multiple continued over-scroll action |

Hopefully everyone can face this problem.. this can also be a behaviour of specific OEMs,
So adding my device for ref: Samsung s10+
Sample Code:

void main() async {
runApp(Test());

class TextScreen extends StatelessWidget {
const TextScreen({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: SafeArea(
child: ListView.builder(
itemBuilder: (context, index) => ListTile(
title: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Text(
index.toString(),
),
Container(

);
}
