We have an Android project that integrates a Flutter module externally. This setup was working fine previously.
Recently, we updated the Flutter module to a newer version which includes some changes, and now the Android project fails to build unless we explicitly add the following dependency in our build.gradle file:
implementation 'com.google.android.exoplayer:exoplayer:2.18.7'
This is strange because the integration method (adding Flutter module externally) hasn't changed, and we haven't updated any native Android code ourselves.
The project structure looks like this:
/android_project
├── app/
├── flutter_module/ ← added as an external module
We are integrating the Flutter module using build.gradle:
repositories {
maven {
url '../flutter_modules'
}
maven {
url "$storageUrl/download.flutter.io"
}

Reset to default 1I did some investigation about this.
After updating the Flutter SDK, I think that the video_player plugin (which uses ExoPlayer) started requiring us to manually declare the ExoPlayer dependency:
implementation 'com.google.android.exoplayer:exoplayer:2.18.7'
BTW they didn’t mention this requirement clearly in the change log.So this might be tied to internal changes in how dependencies are handled.
