Flutterfire: [firebase_auth] ERROR_INTERNAL_ERROR on iOS when Email login

[JonasJW]

When trying to login and sign in with Email I get this Exception:
```
code:"ERROR_INTERNAL_ERROR"
details:null
message:"An internal error has occurred, print and inspect the error details for more information."
hashCode:374231514
runtimeType:Type (PlatformException)
`````

In Console: flutter: PlatformException(ERROR_INTERNAL_ERROR, An internal error has occurred, print and inspect the error details for more information., null)

This only happen with iOS, not with Android. Other firebase services work fine.

I tried it on version 0.13.0 and 0.14.0 and both have the issue

Ran into the same issue.
I was setting up the FirebaseApp and FirebaseDatabase as indicated by this example:
https://github.com/FirebaseExtended/flutterfire/blob/master/packages/firebase_database/example/lib/main.dart

Once I got rid of that code, and just used

final FirebaseApp _firebaseApp = FirebaseApp.instance;
final FirebaseDatabase _firebaseDatabase = FirebaseDatabase.instance;
final FirebaseAuth _firebaseAuth = FirebaseAuth.instance;

It worked fine.
Still a bug though - the ERROR_INTERNAL_ERROR details are null, so very difficult to diagnose.

final FirebaseApp _firebaseApp = FirebaseApp.instance;

doesn't work for me :P , full callstack:

FYI:
only happened with sendSignInWithEmailLink, not signInWithEmailAndPassword.

[samakintunde37]

I've just fixed mine.
Don't know if this would solve yours but I removed my GoogleService-Info.plist, then downloaded it again and added it to my Runner Target again. Then, I ran pod install and it all worked.

not work for me, do you use sendSignInWithEmailLink?

[samakintunde37]

No, I'm using signInWithEmail in my app. I'll take a look at it and see if I can help out though.

[HaoCherHong]

Opened a issue #1514 for sendSignInWithEmailLink

[mackattack3k]

I resolved this by removing my API restrictions in Google Cloud Console for my iOS API key.

Not sure which API that should be enabled though and I don't recommend keeping it unrestricted.

Consolidating under #1456 - we'll be looking at parsing native error messages & codes and bubbling these up to the Dart layer in a consistent cross-platform format.
