I will fix bugs in your flutter mobile app for android and ios
Uzair Ul Hassan
About this gig
Is your Flutter app crashing, showing layout errors, or getting rejected by the App Store? Let's fix it right now.
A single bug can cause users to delete your app or leave negative reviews. As a professional Flutter mobile engineer with live apps on the Google Play Store, I specialize in jumping into existing codebases, diagnosing performance bottlenecks, and delivering clean, error-free solutions.
What I Can Fix For You:
- UI & Layout Issues: Broken layouts, overlapping text, or non-responsive screens on different device sizes.
- Logic & State Management: Debugging issues with BLoC, Provider, Riverpod, or app state tracking.
- API & Backend Errors: Fixing broken REST APIs, data parsing failures, or Firebase connection issues.
- Build & Deployment Failures: Resolving critical crashes, Gradle errors, CocoaPods conflicts, or dependency upgrades.
Why Choose My Service?
- Real-World Proof: I have 2 live apps currently scaling on the Google Play Store (including my Docta Med application), proving my deep understanding of production-ready code.
- Clean Code Standards: Every fix I deploy respects clean architecture rules
️ PLEASE message me with your error logs or repository details BEFORE ordering!

FAQ
Do you need access to my full source code or GitHub repository?
Yes. To diagnose and fix bugs efficiently, I will need access to your Flutter project files or your GitHub/GitLab repository. All your code and data are kept 100% confidential and safe.
Can you fix app store rejection issues on Google Play or Apple App Store?
Yes. I specialize in identifying the technical or policy reasons behind app rejections. I will update the code, resolve dependency issues, or patch compliance bugs so your app passes the review phase successfully.
What if the bug requires changes to my backend or database API?
My packages cover fixing client-side Flutter code. If the bug is caused by a broken third-party API or server-side database issue, I will pinpoint the exact error for you so your backend team can fix it, or we can discuss a custom offer.
Does your basic package include designing or adding new screens?
No. To maintain high quality, my bug-fixing packages are strictly for troubleshooting, optimization, and repairing existing code. If you need new screens or features added, please message me for a custom project quote.
