Unexpected null value auth/firebase_auth/firebase_auth_manager.dart.lib.js

[BenesOndrej]

Can we access your project?

• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

When running the appp in test mode I receive a red error screen with title "Unexpected null value. The relevant error-causing widget was: FutureBuilder" The stack trace then hints an issue with: auth/firebase_auth/firebase_auth_manager.dart.lib.js

I am able to navigate to other pages, but the lading page cannot be tested due to the error. I made no chagnes to the authentication process and can see that the user is correctly authenticated and loaded from Firebase.

Expected Behavior

When app is run in test mode, it opends the landing page with authenticated user.

Steps to Reproduce

1. Create login page and landing page
2. Setup Firebase authentication
3. Run app in test mode
4. Login for first time
5. Get redirected to landing page
6. Landing page throws Unexpected Null Error

Reproducible from Blank

• The steps to reproduce above start from a blank project.

Hello!!

I’m currently testing your project. Do you have a demo user and password I can use to test the full flow? For example:
