Receiving error when creating FirebaseAuth instance create & sign in with email and password

Question

I receive an error in Android Studio when creating a user sign in method using FirebaseAuth and FirebaseUser. Mainly telling me to either cast or change FirebaseUser to AuthResult both of which leads to a failure to create a firebase user resulting in No implementation found for method createUserWithEmailAndPassword on channel plugins.flutter.io/firebase_auth.

I have tried the responses from Android Studio without luck. The best fix is to revert to an earlier FirebaseAuth version. I'm currently using version: firebase_auth: ^0.14.0.

FirebaseUser user = await FirebaseAuth.instance.signInWithEmailAndPassword(email: _email, password: _password);

I receive error: A value of type 'AuthResult' can't be assigned to a variable of type 'FirebaseUser'. when using the above code.

When I change FirebaseUser to AuthResult or cast it as as FirebaseUser , I receive No implementation found for method createUserWithEmailAndPassword on channel plugins.flutter.io/firebase_auth. and it doesn't create the user in the Firebase database.

How can I use the latest version of FirebaseAuth without running into this error?

Edit: I have tried the related questions/answers on the topic to no avail including using latest SDKcompile versions.

Answer 1

There was a breaking change in version 0.12.0. Check the Changelog here: https://pub.dev/packages/firebase_auth#-changelog-tab-

Breaking Change. Sign-in methods now return AuthResult instead of FirebaseUser. Retrieve the FirebaseUser using the user property of AuthResult.

I haven't updated my package yet, but I imagine it would look something like this.

AuthResult result = await FirebaseAuth.instance.signInWithEmailAndPassword(email: _email, password: _password);

FirebaseUser user = result.user;

Answer 2

这对我有用-

AuthResult result = await FirebaseAuth.instance.signInWithEmailAndPassword(email: _email, password: _password);   FirebaseUser user = result.user;

Answer 3

它对我来说是工作（我正在使用firebase_auth：^ 0.14.0 firebase_database：^ 3.0.5），如果它说是不必要的演员，您也可以尝试一下。

FirebaseUser user = (await _firebaseAuth.createUserWithEmailAndPassword(email: email, password: password)) as FirebaseUser;

Answer 4

Casting throws an error. This worked for me:

AuthResult auth = await FirebaseAuth.instance.signInWithEmailAndPassword(email: _email, password: _password);

auth.user // FIREBASE USER
