[fireabse_auth] call reauthenticateWithCredential by EmailAuthProvider using current email and password (NoSuchMethodError: The method '[]' was called on null).

[masashi-sutou]

description

• I use firebase_auth: 0.14.0.
• I would like to update the user's email, but if the user's last sign-in time does not meet the security threshold, I need to use the reauthentication method to resolve.
• I tried to call reauthenticateWithCredential on EmailAuthProvider with my current email address and password before firebaseUser.updateEmail, but the data returned from reauthenticateWithCredential on iOS has no user and crashes with the following error.

error

Tried calling: []("user")
flutter: 💥 #0      Object.noSuchMethod (dart:core-patch/object_patch.dart:50:5)
#1      new AuthResult._ (package:firebase_auth/src/auth_result.dart:12:36)
#2      FirebaseUser.reauthenticateWithCredential (package:firebase_auth/src/firebase_user.dart:214:23)
...

my code

final baseUser = await _firebaseAuth.currentUser();
// occurs error
final authResult = await baseUser.reauthenticateWithCredential(
  EmailAuthProvider.getCredential(
    email: baseUser.email,
    password: password,
  ),
);
return authResult.user;

workaround

• I downgraded to 0.11.1+12, and it works.

final baseUser = await _firebaseAuth.currentUser();
final firebaseUser = await baseUser.reauthenticateWithCredential(
  EmailAuthProvider.getCredential(
    email: baseUser.email,
    password: password,
  ),
);
return firebaseUser;

Getting the same error here.. Workaround also works for me, but don't really like to have to downgrade..

but don't really like to have to downgrade..

@MiguelSOliveira What's your workaround without downgrading?

I'm getting the same error with PhoneAuthProvider.

The problem was probably generated on this commit

Trying to debug it

any update ?

[rodriigovieira]

I was able to reproduce the problem here.

Another possible workaround is simply reauthenticate the user again.

await _auth.signInWithEmailAndPassword(email: _user.email, password: currentPassword);
