FireBaseUser not defined.

[codecrypt112]

when I write "FirebaseUser", it shows

Undefined class 'FirebaseUser'.
Try changing the name to the name of an existing class, or creating a class with the name 'FirebaseUser'.dart(undefined_class)

Please anyone help.

I'm sure you've figured it out by now but in case anyone else sees this thread, I was experiencing the same unit lI realized I hadn't imported the firebase lib yet. add this to the top of your page:

import 'package:firebase_auth/firebase_auth.dart';

Hi, I am facing an error with google sign in for Firebase. Please suggest any fixes.

FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':google_sign_in:processDebugGoogleServices'.

File google-services.json is missing. The Google Services Plugin cannot function without it.

Hi @janasathish your google-services.json is missing maybe you haven't places it in the right place or else you have not named it correctly it also happened with me i had a space remaining while renaming the file for reference use this YouTube video https://www.youtube.com/watch?v=LeTgMYlGVrM

Hi! They have done some migration so FirebaseUser is now just User, you need firebase_core and some other stuff. Refer to this document. https://firebase.flutter.dev/docs/migration/
Hope it helps!

how do i initialise non-nullable instance field of '_id' for the class Post. will the database be affected if i were to place late modifier?

error from IDE:
Non-nullable instance field '_id' must be initialized.
Try adding an initializer expression, or add a field initializer in this constructor, or mark it 'late'.
