Flutter and Next js Developer: Apps and Web Built as One System
About this Gig
Is your Flutter or FlutterFlow app crashing, throwing Dart exceptions or showing broken UI? I find the root cause and fix it properly: clean, tested, explained.
I fix Flutter and FlutterFlow apps on iOS and Android. Null safety errors, widget overflow, Firebase/Supabase issues, Riverpod/BLoC/GetX bugs, broken REST API calls, Figma to Flutter mismatches and build failures.
FlutterFlow: I fix custom widgets, custom actions and custom functions inside your project, and bugs in exported Dart code. I tell you which approach your fix needs before I start.
What counts as one bug: one reproducible issue on one screen or function. One root cause affecting several screens is still one bug. Unrelated issues count separately.
What you get:
- Root cause identified, not patched over
- Clean Dart following Flutter conventions
- Tested on iOS and Android before delivery
- A short write-up of what was wrong and why
- Source code via private GitHub repo or zip
- Revisions until the reported bug is verified fixed
Stack: Flutter, Dart, FlutterFlow, Firebase, Supabase, Riverpod, BLoC, GetX, REST APIs, Google Maps, Stripe, AdMob.

FAQ
What types of Flutter bugs can you fix?
I fix all types — null safety errors, widget overflow issues, dart exceptions, Firebase and Supabase integration, Riverpod and BLoC state management issues, REST API and JSON parsing errors, Google Maps and Stripe integration, UI pixel mismatch from Figma and Play Store or App Store build failure.
Do I need to share my full source code?
Yes, I need access to the relevant Flutter project files to diagnose and fix the issue properly. You can share via a private GitHub repo, a zip file or Google Drive. All code shared with me is kept strictly confidential and never shared with anyone.
What if you cannot fix my bug?
Message me before ordering and describe the issue. I will assess it honestly and only confirm the order if I am confident I can fix it. I do not accept orders I cannot deliver on, this protects your time and mine.
Do you work with FlutterFlow projects?
Yes. I fix custom widgets, custom actions and custom functions inside FlutterFlow, and bugs in exported Dart code. Message me with your project link or export and I will tell you what is fixable before you order.
Will my FlutterFlow fix survive a re-export?
Depends on where the fix lives. Fixes inside FlutterFlow custom functions, actions, widgets, builder config survive every export. Some problems can only be solved in exported Dart and those are overwritten the next time you export from FlutterFlow. I tell you which one applies before I start.
