App Crashes in TestFlight During Phone Login (Works in FlutterFlow Testing)

Job ID: 39504851

Budget: $10 – $30 USD

Issue:

The app works correctly in the FlutterFlow testing environment when authenticating with test phone numbers.

But it crashes abruptly in TestFlight (production build) when a real user attempts to log in or register with their number.

It fails before sending the verification SMS—the crash occurs first.

Technical Context:

Development: FlutterFlow (Firebase Auth + Firestore).

Testing Environment: Phone authentication works fine with test numbers (FlutterFlow).

Production Environment (TestFlight): Crashes when entering a real number.
