FlutterFlow and Xano Debugging Specialist

Hi!

I’m building a FlutterFlow mobile app connected to Xano as the backend, and I need help debugging my authentication setup.

Current setup
• FlutterFlow frontend
• Xano backend
• Auth endpoints:
• auth/signup
• auth/login

Both endpoints work perfectly when tested directly in Xano using hard-coded JSON values.

The issue
When I try to sign up or log in via FlutterFlow using form inputs, Xano returns a error message

Key detail:
• If I hardcode the email value directly inside the FlutterFlow API request body, the request succeeds.
• The error only happens when using dynamic bindings from form fields, which suggests the email variable is being sent as empty or incorrectly formatted.

What I need help with
I’m looking for someone experienced with FlutterFlow + Xano to:
1. Review my API call variable bindings for signup and login.
2. Verify that email, password, and name are correctly mapped from Widget State.
3. Check whether trimming, null values, or formatting issues are causing the invalid email error.
4. Test the end-to-end signup and login flow using dynamic user input and confirm it works.

Access
• I can safely share my FlutterFlow project
• I can provide Xano API details and screenshots as needed

Please include in your proposal
• Your experience with FlutterFlow Xano integrations
• Examples of similar auth/debugging work (if available)
• Your estimated turnaround time

Thanks!
