Hello,

I use a MKMapView (Apple Maps) inside a PlatformView and it’s working fine.
But after using a SearchView (with showSearch) and dismissing it, the platformView is only responding to touch events for one more time.
After that, nothing happens if you try to move the map or zoom etc.
Every other flutter widget on screen is still working fine.

This affects both debug builds and release builds and it affects simulator (most of the time) and real devices (all the time).

I also uploaded a demo project on google drive, so you can reproduce the bug.
The bug occurs most of the time but if not, please close and restart the app and follow the steps again.

Video of bug:

Demo project:

Steps to Reproduce

  1. Move the map (then wait until touch is finished / animation finished)
  2. Press SearchButton
  3. Press dismiss button (in the top left corner)
  4. Move the Map (then wait until touch is finished / animation finished)
  5. Try to move the map again -> Map not moving/interactive anymore
    If the map is still interactive, repeat steps 2 through 5
    If the bug still not occurs, try closing and reopening the app and follow the steps again.

    I'm having the same problem with a stack that contains a PlatformView with MKMapView and a MaterialButton, after pressing the MaterialButton twice the MKMapView stops responding. Before pressing the MaterialButton everything works as expected.

    Same issue on Flutter v1.12.13+hotfix.8.
    Also we had explored, that it can be not just MaterialButton or any other interactive widget. Touch to any Flutter view that is over the map leads to that behaviour. It works even with Text widget.

    However, associated PlatformChannel still handle calls. So, i believe, that issue is related to gesture responding system.

    Strange thing about this is that library has another behaviour. It doesn't stop responding at all, but after pressing the button over the map, it always skips next gesture on map, but continue responding on next gesture.

    Links provided by author seems to be broken, so i'll provide repo to reproduce issue later

    Same issue on Flutter v1.12.13+hotfix.8.
    Also we had explored, that it can be not just MaterialButton or any other interactive widget. Touch to any Flutter view that is over the map leads to that behaviour. It works even with Text widget.

    However, associated PlatformChannel still handle calls. So, i believe, that issue is related to gesture responding system.

    Strange thing about this is that library has another behaviour. It doesn't stop responding at all, but after pressing the button over the map, it always skips next gesture on map, but continue responding on next gesture.

    Links provided by author seems to be broken, so i'll provide repo to reproduce issue later

    I fixed the links

    I downloaded your demo link and compiled on latest master, but getting bunch of Xcode errors as below:

Could not build the application for the simulator.

    Hence I am unable to verify this issue on latest versions. Can you check and fix the demo link and provide a github repo instead that we can clone and run directly to verify this issue ?

    Without additional information, we are unfortunately not sure how to resolve this issue.
    We are therefore reluctantly going to close this bug for now.
    Please don't hesitate to comment on the bug if you have any more information for us; we will reopen it right away!
    Thanks for your contribution.

    Could everyone who still has this problem please file a new issue with the exact description of what happens, logs, and the output of flutter doctor -v.
    All system setups can be slightly different, so it's always better to open new issues and reference related issues.

    Looks like it might be a similar problem with #33988. Have you tried to use the new WaitUntilTouchesEndedPolicy? See an example: flutter-team-archive/plugins#2746

    @cyanglaz Unfortunately the new gesture recognizers policy changed nothing, the issue still persists

    @maxiundtesa I suspect it is related to how the MKMapView is implemented. There might be some gestures or implementation details in touch event handling delegate methods (e.g. touchesBegan) conflicts with flutter's gesture handling mechanism.

    Yeah, looks a bit like that, since that issue is apparently only prevalent with MKMapView…
    So it‘s not the highest priority bug, but still would be nice to have it working for the native feel on iOS in the long term

    Adding gestureRecognizersBlockingPolicy: FlutterPlatformViewGestureRecognizersBlockingPolicyWaitUntilTouchesEnded to FlutterPluginRegistrar register fixed the issue for me

    gestureRecognizersBlockingPolicy: FlutterPlatformViewGestureRecognizersBlockingPolicyWaitUntilTouchesEnded

    Is there any potential impact on the project if this parameter is added?
