Hi @Justus-M, is this limited to only windows or do you experience it on other platforms as well?

Can you share the code sample you use as well?

I haven't had time to create a minimum reproducible example but I imagine you can just use the example app and print FirebaseAuth.instance.currentUser immediately after initializing firebase.

I have added a delay of a few seconds and then it is no longer null, so to be honest this is no longer a priority for me. I believe it's an issue with the library so I wanted to bring it to your attention since flutterfire is still in the early stages for windows and has various issues.

But the code is literally just

print(FirebaseAuth.instance.currentUser)

This prints null on windows after initializing firebase, even if the user was logged in before closing the app.

On mac, web, and mobile it does not return null

Hey @Justus-M. We need more information to resolve this issue but there hasn't been an update in 7 weekdays. I'm marking the issue as stale and if there are no new updates in the next 7 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

I provided more information

Sorry for the delay, it seems like the bot didn't remove the blocked label so I missed it in my notifications.

Reproducible using the plugin example app. I was already logged in, but the user came as null before the data was fully loaded.

Thanks for the report, I'm looking into it

This happened on other platforms as well, tested on android

@Lyokone Is it possible that this also has an impact on the authentication for Firestore requests shortly after creating a new account?

I have the following issue: after creating an account with createUserWithEmailAndPassword on windows, I try to add a document to Firestore but the Firestore security rules reject the operation. It seems that even though FirebaseAuth.instance.currentUser is not null, firestore security rules don't recognize the user as being authenticated (the security rules check that the user is authenticated, and that the users id matches the document ID).

When I restart the app after creating the user (or log in with an existing user in the first place), it works fine.

Unfortunately I haven't been able to create a minimum reproducible example (for some reason I can't reproduce it in the test app), so I figured I'd ask you since you worked on a potentially related issue.

I am seeing this issue too on Windows. After I sign in/anonymous sign in, hot restarting the app returns currentUser as null. This also happens on subsequent app runs too.

In my case, it is always null, even after few seconds. I tried this:

 FirebaseAuth.instance.authStateChanges().listen((event) {
      print('Auth state changed: $event');
    });

and it only prints null and never prints again.

someone solved the problem ?

I haven't. This makes our app useless on Windows! 🥲

u can make delay its work but still bad !

I can't. Its not that it is only null for the first few seconds...it stays null. So it always logs out users when reopened.
