# CAREFUL, You may need to allow fine location permission on device first
- launchApp: 
        appId: ${APP_ID}
# open map
- tapOn: "Full screen map"

# Stop and launch app
- repeat: 
        times: 15
        commands: 
              - pressKey: home
              - launchApp: 
                      appId: ${APP_ID}
                      stopApp: false
              - waitForAnimationToEnd: 
                      timeout: 5000

I just copied the code from the google maps plugin but in fact we just need to invalidate the texture view, not all the mapview

Thanks for contributing!

It would be good if some more people who had the issue could test this approach and comment here, since I can't reproduce the original issue.

I tried on my Samsung Note8 (SM-N950F - Android 9) and the fix is working great !

I can still reproduce the bug on my phone.
It's a Samsung Galaxy s9, android 10

I can not reproduce this, can you let me know under which conditions this appears?
Is this tied to a specific Android SDK version or are there already fixes in a later Flutter SDK?

What i've done to test:

1. I forked your branch
2. created a tag to be able to include it in my project. (Maybe there is an easier solution)
3. added this to pubspec.yaml
4. Also tested enabling impeller engine for android (added in manifest)

dependency_overrides:
    maplibre_gl_platform_interface:
      git:
        url: https://github.com/f1sh1918/flutter-maplibre-gl.git
        path: maplibre_gl_platform_interface
        ref: test
 dependencies:
   maplibre_gl:
    git:
      url: https://github.com/f1sh1918/flutter-maplibre-gl.git
      ref: test

For me the bug is still reproduceable on Android 9 and Android 14 even with your changes
Tested on browserstack

environment:
  sdk: 3.3.1
  flutter: 3.19.3
