I will fix flutter app bugs, crashes and errors for android and ios
About this Gig
Is your Flutter app crashing, throwing errors, or behaving unexpectedly on Android or iOS? I'll find the root cause and fix it fast.
I'm a Senior Flutter Developer with 3+ years of production experience. I've debugged and resolved:
Common issues I fix:
App crashes and null safety errors (Dart exceptions)
UI glitches, rendering issues, and layout overflow errors
Firebase Auth, Firestore, and push notification bugs
REST API integration errors and response handling issues
Navigation and routing problems (GoRouter, Navigator 2.0)
State management bugs (BLoC, Provider, Riverpod)
Performance issues: jank, slow builds, memory leaks
Platform-specific issues (Android/iOS permissions, build errors)
How it works:
1. You share your code (private repo or zip) + describe the issue
2. I reproduce, diagnose, and fix it
3. I deliver fixed code with clear comments explaining what was changed
All packages include:
Source code with fix applied
Written explanation of the root cause
23 revisions if the issue persists
Before ordering, please have ready:
Access to your Flutter project (GitHub / zip)
A clear description of the bug and steps to reproduce it
Error logs or screenshots if available

FAQ
1. What types of bugs do you fix?
UI glitches, navigation issues, API integration errors, authentication problems, and performance issues in Flutter apps.
2. Do you fix backend or server bugs?
No. This gig is only for Flutter mobile apps. Backend/API fixes are offered in a separate gig.
3. Will you explain the fix?
Yes. Every fix includes code comments so you understand what was changed.
4. What if my bug is complex?
If the issue requires more than the package limit, I’ll suggest a custom offer tailored to your project.
5. Do you sign an NDA to protect my source code?
Yes, I'm happy to sign a basic NDA before reviewing your code. Your intellectual property stays private and I will not share or reuse any part of your project.
6. What if you can't reproduce or fix the bug?
If I genuinely cannot reproduce or resolve the issue after thorough investigation, I'll refund your order in full. I'll also provide a written diagnosis of what I found so you're not left empty-handed.
7. Can you fix bugs caused by a Flutter or Dart version upgrade?
Yes. Version migration issues — including null safety migration, deprecated APIs, and package compatibility errors after upgrading Flutter or Dart — are some of the most common things I fix.
