About this Gig
Flutter or React Native app crashing, not building or rejected by the store? We find the bug and fix it, often in a day.
Gradle build failed? "Null check operator used on a null value"? White screen on launch? Firebase broke after an update? Play Store asking for a new target API level?
Most of these come from package versions that drifted apart after a Flutter or Android update. We fix the cause, not just the line that threw the error, and test it on a real Android and iOS build.
What we fix:
- Flutter bug fix: crashes, errors and broken screens
- Gradle, CocoaPods and Xcode build errors
- Flutter Firebase and Supabase login, database and push issues
- API calls, state management and slow screens
- Play Store target API and App Store rejection fixes
- React Native and Expo app bugs and crashes
Also covered:
- Android bug fix and iOS bug fix in native code
- Flutter and package upgrades to the latest stable version
- Updated build uploaded to Play Store or TestFlight
You get the fixed code in your repo, a full documentation...
Send a screenshot of the error and we'll tell you if it's a quick fix before you order.

FAQ
Can you build a full Flutter app, not just fix one?
Yes. We build full Flutter and React Native apps for Android and iOS, from design to Play Store and App Store launch, with Firebase or Supabase behind it. Send your idea and we'll reply with a feature list, timeline and custom offer.
What do you need from me to start?
A screenshot or screen recording of the error, and access to your code on GitHub or as a zip. If the bug only happens on a real device, tell us which phone and OS version. We confirm the fix before you order.
What if the bug is bigger than the package I picked?
We tell you before we start. If it needs more work, we send a custom offer with the exact scope, so you never get surprised halfway through. Small extras like one more bug are added at the listed extra price.
