Looking for a reliable Flutter developer to fix bugs, crashes, and errors in your Flutter app? I specialize in Flutter bug fixing and debugging for mobile apps on Android and iOS.
With 2+ years of experience, I work on real-world Flutter apps and help fix everything from small UI issues to difficult Flutter errors, crashes, and build problems.
What I Fix:
- Flutter bugs, crashes, runtime and compile errors
- UI, layout, overflow, and widget issues
- State management bugs (Riverpod, Bloc, Provider, GetX)
- Firebase issues (Auth, Firestore, FCM)
- API, JSON, and asynchronous code errors
- Android and Android Studio build errors
- iOS, Xcode, permissions, and compatibility issues
- Performance and memory-related problems
- Null safety and navigation errors
Why Work With Me:
- 2+ years of Flutter & mobile app development
- Experience with production apps and 100K+ downloads
- Clear communication and regular updates
- Clean and maintainable fixes
- Testing before delivery
Whether you have one Flutter bug or several issues across your app, I'll help identify the cause and fix it properly.

FAQ
What do you need from me to start debugging?
I'll need your Flutter source code (via repo link or zip), a clear description of how to trigger the bug, and any console error logs or screenshots you have.
Is my source code secure and private?
100%. Your codebase stays entirely confidential. I never share code snippets or project details with anyone, and I am happy to sign an NDA if required.
What types of Flutter issues can you fix?
I handle runtime crashes, blank screens, UI pixel overflows, unexpected null safety errors, broken navigation routes, and API communication failures.
Do you work with Bloc, Provider, GetX, and Riverpod?
Yes. I regularly work across all major state management libraries and can track down where your app's state is leaking or updating incorrectly.
Can you fix Firebase or database errors?
Yes, including broken Firestore queries, security rules conflicts, authentication token expiration issues, and Cloud Messaging configuration bugs.
Can you fix Android and iOS build/compilation errors?
Yes. If your app is failing to build due to Gradle conflicts, Podfile errors, or outdated package dependencies, I can sort them out.
Can you help improve app performance or lag?
Yes, particularly in the Premium package where I review frame drops, excessive widget rebuilds, and memory leaks.
What if the same bug happens again after delivery?
Every package comes with revision windows. If it's the exact bug we targeted and it resurfaces within that period, I'll fix it immediately at no extra cost.
Can you publish my app to the stores after fixing the bugs?
I focus strictly on debugging here, but I also handle full app store deployment—feel free to message me to bundle a publishing package together.
Should I message you before buying?
If you're not sure which package or whether your issue fits the scope, please message me before ordering. Send me a brief description of the problem or your error log, and I'll help you choose the right package.
