Flutter Unhandled Exception: MissingPluginException(No implementation found for method getAll on channel plugins.flutter.io/package_info)

Question

I've had this issue now for a few days and can't find a solution. If i start my app with flutter run --debug --flavor dev i get 'Unhandled Exception: MissingPluginException(No implementation found for method getAll on channel plugins.flutter.io/shared_prefere nces)'.

I already tried restarting/wiping the emulator, flutter clean, different emulator, removing other plugins and changing the proguard rules as mentioned here.

This is my MainActivity.java file, i am using the v2 embedding:

package de.example;
import io.flutter.embedding.android.FlutterActivity;

public class MainActivity extends FlutterActivity {}

Any ideas? Thanks in advance!
