Flutterfire: [firebase_auth] <Exception has occurred. PlatformException (PlatformException(FirebaseException, An internal error has occurred. [ 7: ], null)) FLUTTER>

[danielgchap]

Hey all,

I have a flutter app with Flutter v1.10.14 that points to Firebase and I'm on the master channel.
Absolutely NOTHING has changed in my code or my Firebase setup.
All I did was got a Flutter Upgrade notice in Visual Studio and I did that.

Now every time I go to log into my app with credentials that definitely work I get the following:

Firebase Exception: "An internal error has occurred. [ 7: ]"

Here is the code being called, nothing is null, this has just suddenly started happening out of nowhere:

@override
Future signInWithEmailAndPassword(
String email, String password) async {
final AuthResult result = await _firebaseAuth.signInWithEmailAndPassword(
email: email, password: password);
return result.user;
}

I'd really appreciate your help. There are no issues when flutter doctor is run.

A little more input:

• I'm using a device (Android) that has been logging in just fine all day: Can't log in for some reason
  
  
  
  • Works fine on Android emulator
  
  

Also this:

E/FirebaseInstanceId( 3674): Token retrieval failed: SERVICE_NOT_AVAILABLE
W/BiChannelGoogleApi( 3674): [FirebaseAuth: ] getGoogleApiForMethod() returned Gms: com.google.firebase.auth.api.internal.zzak@4b2e98a
E/flutter ( 3674): [ERROR:flutter/lib/ui/ui_dart_state.cc(148)] Unhandled Exception: PlatformException(FirebaseException, An internal error has occurred. [ 7: ], null)

This seemed to be associated with the firewall settings in my apartment. Sorry to waste your time if you're reading this!

Hey, I believe I am having the same problem. How did you fix your issue with your firewall? Thanks in advance!

I having the same issue before. And I found that this issue occurred because there is no internet connection for my phone.

Having exactly same issue while testing on emulator:
PlatformException(FirebaseException, An internal error has occurred. [ 7: ], null).
Any suggested solution?

I have also encountered this problem several times but the solution that has been working for me was either to restart my emulator or recheck on my internet connectivity

My wifi firewall stopping my internet from working on my emulator. That was what helped me!

[arfa123]

check your internet connection, maybe switched off.

In my case I hadn't enabled Anonymous Sign-in Method in the Firebase Console
