@maheshmnj: I updated the example in a pull request that may fix it. You need to scroll quite aggressively in that simple example to reproduce it 😄 |

Thanks for the code sample @kristoffer-zliide, Can you please clarify on which platform is this issue on ? Screen.Recording.2022-04-29.at.12.27.02.PM.mov
I tried to reproduce the issue on Android, either I was not aggressive enough xD or the bug does not exist on Android code sampleimport 'package:flutter/gestures.dart';
import 'package:flutter/material.dart';
import 'package:url_launcher/link.dart';
void main() {
runApp(MyApp());
}
class _HorizontalScrollBehavior extends MaterialScrollBehavior {
@override
Set<PointerDeviceKind> get dragDevices => <PointerDeviceKind>{
PointerDeviceKind.touch,
PointerDeviceKind.stylus,
PointerDeviceKind.invertedStylus,
PointerDeviceKind.mouse,
};
}
/// App for testing
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) => MaterialApp(
home: Scaffold(
body: ConstrainedBox(
constraints: const BoxConstraints(maxHeight: 300),
child: const _List(),
),
),
);
}
class _List extends StatelessWidget {
const _List({
Key? key,
}) : super(key: key);
@override
Widget build(BuildContext context) => ScrollConfiguration(
behavior: _HorizontalScrollBehavior(),
child: ListView.separated(
scrollDirection: Axis.horizontal,
itemCount: 500,
separatorBuilder: (_, __) => const SizedBox(height: 24, width: 24),
itemBuilder: (_, int index) => Link(
uri: Uri.parse('https://example.com/$index'),
builder: (_, __) => GestureDetector(
onTap: () {
ScaffoldMessenger.of(context).showSnackBar(
SnackBar(content: Text('https://example.com/$index')));
},
child: Card(
child: Padding(
padding: const EdgeInsets.all(64),
child: Text('#$index', textAlign: TextAlign.center),
)),
),
),
),
);
}
flutter doctor -v (mac) |

@kristoffer-zliide Unfortunately that doesn't seem to make any difference , I am unable to reproduce the error on Windows Web / Desktop app 2022-04-29.20-01-53_Trim.mp42022-04-29.19-44-26_Trim.mp4flutter doctor -v (windows)details> |

@maheshmnj: maybe a little more aggressive: 😃 Screen.Recording.mp4Or, are you running directly from the PR, because there the issue is fixed? |

The PR I believe fixes it, the one I linked to with the example. It's a fix to the plugin, so it's not from flutter master, and I'm also running stable 2.10.5. But if you're running on just the example Flutter code, I think you should be able to repro it. |

@kristoffer-zliide I am trying this code sample , Can you please confirm if the issue reproduces with that sample? Also looking at your logs the error doesn't seem related to URL launcher But looks similar to #91814 |

@maheshmnj: really sorry, I didn't see the code in your reply because it was collapsed! That code should repro it with url_launcher 6.1.0. Both in the error I posted and in the repro video, you can see |

@maheshmnj : maybe try this and scroll fast downward with the mouse wheel: |

Thanks for the code sample @kristoffer-zliide, I was able to reproduce the issue on stable and the master channel. On Scrolling a bit faster the exception is thrown. A reproducible code sample can be found here #102741 (comment) 2022-05-04.12-03-06_Trim.mp4The logs don't seem to point at the issue in the URL launcher plugin, so labeling it as a framework issue. logsflutter doctor -v (windows) |

onPlatformViewCreated calls setState(), so it probably shouldn't be called indiscriminately after an async operation. Or, maybe onPlatformViewCreated shouldn't call setState without checking mounted state.
Easily reproducible by making a large list of widgets with Links and scroll through it.
