Persisting MissingPluginException in Flutter

Hello developers of the world!

I have a persisting issue with using a specific Flutter package for Android and iOS.

MissingPluginException(No implementation found for method getTemporaryDirectory on channel plugins.flutter.io/path_provider)

This raises when I use a function of audioplayers (https://pub.dev/packages/audioplayers).

This is not a story of hot restart. I also tried the solution proposed here https://stackoverflow.com/a/66593064/8791925 but I got no improvement.

The content of my MainActivity.kt is

import io.flutter.embedding.android.FlutterActivity
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.plugins.GeneratedPluginRegistrant

class MainActivity: FlutterActivity() {
    override fun configureFlutterEngine(flutterEngine: FlutterEngine) {
        GeneratedPluginRegistrant.registerWith(flutterEngine);
    }
}

Edit:

I add the content of the pubspec.yaml concerning dependencies


dependencies:
  flutter:
    sdk: flutter

            android:exported="false"
            android:stopWithTask="false"
            android:foregroundServiceType="mediaPlayback"/>
    </application>
</manifest>

Do you see what I can be missing?

Thank you for your help.

Answer

I finally found the solution: upgrading packages (flutter pub upgrade). By chance, the issue was fixed by maintainers of path_provider. I was in version 2.0.10 when the issue occurs and the version 2.0.11 fixes it.

Explanation

I tried to do this but only in December, when I got the issue for the first time and it did not solve it at this time.

To understand the origin of the fix, I checked which packages were updated in pubspec.lock. I saw that path_provider_android was updated and not path_provider became 'transitive':

  path_provider:
    dependency: transitive
    description:
      name: path_provider
      url: "https://pub.dartlang.org"
    source: hosted
    version: "2.0.8"
  path_provider_android:
    dependency: transitive
    description:
      name: path_provider_android
      url: "https://pub.dartlang.org"
    source: hosted
    version: "2.0.11"
