I can't launch a Flutter project in Android Emulator after upgrade Flutter. I obtain the following message in the debug console:

W/FlutterEnginePluginRegistry( 7750): Attempted to register plugin (io.flutter.embedding.engine.plugins.shim.ShimPluginRegistry$ShimRegistrarAggregate@75e268b) but it was already registered with this FlutterEngine (io.flutter.embedding.engine.FlutterEngine@d56f368).

It worked fine before Flutter upgrade. I detected that the problem is with Firebase plugins. I created a new empty Flutter project and it works ok. After add firebase_auth plugin, I obtain the above messge again.

I tried to clean the project, different Firebase versions, restart and create new emulators, ...

My flutter version:

According to the output of flutter doctor, you are using the master channel.

From the documentation:

master

The current tip-of-tree, absolute latest cutting edge build. Usually functional, though sometimes we accidentally break things.

Therefore you might have some issues, and it seems this is one of them.

You can use the stable channel for now:

stable

When we believe we have a particularly good build, we promote it to the stable channel. We intend to do this more or less every quarter, but this may vary. We recommend that you use this channel for all production app releases. We may ship hotfixes to the stable channel for high-priority bugs, although our intent is to do this rarely.

Latest version released was v1.12.13+hotfix.5

https://github.com/flutter/flutter/wiki/Flutter-build-release-channels

https://flutter.dev/docs/development/tools/sdk/releases

You can switch channel by executing:

flutter channel stable

Had a similar issue with AndroidAlarmManagerPlugin.

Deleting "AlarmService.setPluginRegistrant(this);" in Application's onCreate fixed it for me.
