🚀 [firebase_auth] Add timeout case in exceptions thrown by createUserWithEmailAndPassword

[Ortes]

I literally spent hours to understand where this firebase_auth/unknown came from. I finally findout that was my beforeUserCreated override that was too long and thus the call timed out.

Just adding this case in exceptions thrown would be nice to prevent anyone else to have this problem

: 🔴 [AUTH_SERVICE] Error type: FirebaseAuthException

Hey, thanks for the report!

The error code and message come directly from the native Firebase SDK — we pass them through as-is. If the Android SDK returns UNKNOWN for blocking function timeouts, that's an upstream issue. I'd recommend opening an issue on the Firebase Android SDK to get a dedicated error code for this case.
