I'm getting an error “Error type 'AuthResult' is not a subtype of type 'FirebaseUser' in type cast” when I'm trying to login or signup

Question

I\'m making a flutter app for my college project, where I\'m adding a login and signup page and authenticating it via Firebase, and when I click login the debug console says

Answer 1

I had same error and changed code to:

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

The app works as expected on a real device, without an error in the console, but Visual Studio Code shows red underline at the end below user and outputs an error:

The getter 'user' isn't defined for the class 'FirebaseUser'. Try importing the library that defines 'user', correcting the name to the name of an existing getter, or defining a getter or field named 'user'.

[Solution] Restart VS Code. VS Code uses the old library until restart.
