This is happening in the deprecated Firebase Instance ID SDK and shouldn't happen if you use the FCM SDK by itself (which is recommended).

Since you're using the firebase_messaging Flutter plugin but don't seem to be including firebase-iid directly, the dependency could be coming from the FCM plugin (maybe https://github.com/firebase/flutterfire/blob/6be9597301aadf9673535fd4ef3fd4fda92ead6a/packages/firebase_messaging/firebase_messaging/android/build.gradle#L69, if that's what you're using). This probably should be removed, but I'm not familiar enough with the Flutter plugin to know if it's possible or how difficult it would be. You could file a request on the plugin to remove that dependency so someone on that team can take a look.

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Can you point me towards the original bug tracking that happened in Firebase instance iid, so that I can raise a proper request?
Removing firebase instance iid from plugin side doesn't seem possible since flutter flutter-fire plugin dependencies will override anything

There wasn't an issue filed since it was discovered during cleanup of firebase-messaging after the deprecation of firebase-iid.

I'm not familiar with Flutter's integration of firebase-messaging, but all apps should move towards only using firebase-messaging since firebase-iid is deprecated and is no longer updated. Flutter should be trying to remove the firebase-iid dependency, wherever it is coming from, but I don't know what's the right avenue to make that request.
