🐛 [firebase_auth] MissingPluginException(No implementation found for method listen on channel plugins.flutter.io/firebase_auth/id-token/[DEFAULT])

jangruenwaldt commented 2 years ago

Bug report

In crashlytics, I get the following error, only on Android devices running Android 10/11, never on iOS:

Non-fatal Exception: io.flutter.plugins.firebase.crashlytics.FlutterError: MissingPluginException(No implementation found for method listen on channel plugins.flutter.io/firebase_auth/id-token/[DEFAULT]). Error thrown Instance of 'WC'.
   at .#0      MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:154:7)
   at .#1      EventChannel.receiveBroadcastStream.<anonymous closure> (package:flutter/src/services/platform_channel.dart:486:9)

It seems to occur after launching the app. Some devices where this happens: Samsung Galaxy S20, Pixel, Pixel 5, S20 Ultra 5G

Describe the bug Exception being thrown that makes plugin unable to function

Steps to reproduce

Steps to reproduce the behavior:

Launch the app which uses FirebaseAuth.instance.authStateChanges() and observe eventually this exception

Expected behavior

No exception

Sample project

Can not reliably reproduce this, so hard to do.

I have followed all the documentation as provided, let me know how I can provide more info. This issue seems to occur for a long time already. I'm a bit confused why no one else experienced it.

darshankawar commented 2 years ago

@jangruenwaldt MissingPluginException is thrown indicating there is some method on the Dart side of the channel that is not implemented on the native side.

In your case, it's throwing No implementation found for method listen on channel plugins.flutter.io/firebase_auth/id-token/[DEFAULT]. The method listen seems to be present already.

Can you try the official firebase_auth plugin example and see if you still get a similar issue with it too ?

Also, please provide entire / complete log of the exception.

Hi, thanks for the answer. I already posted the entire log, there are no more lines. It's from crashlytics.

Unfortunately I can not reproduce it easily, but crashlytics logs shows it happening quite often.

Since I only call a valid method in the Flutter side, I don't think this issue should happen. I will let you know if I find any further information.

The only method I call is listed on the original post.

Another thing is, that it only happens for Android, not iOS. So, I will post my build.gradle files below to help diagnosis:

This might be related: https://github.com/flutter/flutter/issues/37839

Would be great to have proper documentation here for what is required in terms of obfuscation. Thank you!

I tried firebase_auth plugin example on Android and played around a bit but couldn't get to replicate the issue. Keeping it open for further insights from the team.

Thank you. We'll try excluding com.firebase.* from proguard and report if the issue disappears.

I experienced a similar issue here. This is how i managed to fix it , which is probably not right way, but got me going. I changed firebaseAuth.idTokenChanges() to firebaseAuth.authStateChanges() then closed and run the app again and the error was no longer there

Hm, that would be weird if that was really the cause.

By the way, for anyone else reading this: the issue stopped appearing for us when we changed our proguard rules to this:

proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'

As well as excluding com.firebase.* in proguard-rules.pro

Might not be related, since no way to know if this is causality, but since it does not occur anymore, issue could be closed for us.
