About this Gig
Stuck on something FlutterFlow can't do, or an error you can't trace?
I'm a FlutterFlow developer who writes the Dart code the visual builder can't. Our team writes Flutter and native Android/iOS code every day.
What I fix or build in your FlutterFlow project:
- Custom widgets, custom actions and custom functions
- Google and Apple sign-in and other auth errors
- Firebase or Supabase queries and wiring
- Android and iOS build errors
- Code-export cleanup or a Play Store / App Store release
How it works:
- Message me first with the error and a screen recording
- Invite me as a collaborator or share a project copy. No passwords.
- You get the fix in your project, a demo video and a short change note
Not included: redesigns, new backend schemas in Basic, or work past FlutterFlow's limits without a quote. If something can't be done, I tell you before I start.
My profile has 53 reviews at a 4.9 rating, nearly half for mobile bug fixing, and I reply fast.
Send your FlutterFlow project link and the error, and I'll confirm the scope before you order.

FAQ
What if FlutterFlow can't do what I need?
I'll tell you before I start. Options are custom Dart code or a code export at a quoted price. If neither suits you, we cancel before work starts and you pay nothing.
How do I give you access to my FlutterFlow project?
Invite me as a collaborator in FlutterFlow or share a project copy. For Firebase or Supabase, add me as a project member. Never send passwords, keys or keystores.
Can you fix Google or Apple sign-in in my FlutterFlow app?
Yes, in most cases. Common causes are missing SHA keys, OAuth client settings or iOS URL schemes. Message me the exact error and a screen recording first.
What counts as one issue?
One bug you can reproduce with clear steps, or one custom widget, action or function from a written spec. New problems found along the way are quoted separately.
Do you work with Supabase as well as Firebase?
Yes. I can fix queries, auth and data wiring for both, inside FlutterFlow or through a custom function or action.
Can you publish my FlutterFlow app to the Play Store or App Store?
I can help. Inside FlutterFlow this depends on FlutterFlow's own Flutter version, so sometimes a code export is needed. I'll check your project first.
