Flutter Login Error Bug Fix

Job ID: 40426793

Budget: $30 – $250 USD

I have a small Flutter app that suddenly started throwing error messages whenever a user attempts to sign in. The UI loads fine, so the issue is purely functional and isolated to the Login/Authentication flow.

What I need from you: trace the root cause of the error message, implement a clean fix, and make sure users can log in again without side effects. The project is otherwise stable; no new features are required—just a solid repair that keeps the existing code style intact.

You will receive the current source, the exact error log, and test credentials as soon as we start. Please return the corrected code (or relevant patch) along with a short change log so I can see what was adjusted and why.

If you’ve solved similar Flutter authentication glitches before—especially those involving FirebaseAuth or custom back-end tokens—you’ll feel right at home. Let’s get this wrapped up quickly so the app is back in users’ hands.
