About this gig

Is your Flutter app crashing, freezing, or getting rejected from the Play Store or App Store? I will find and fix your Flutter bugs fast with clean, documented code and a clear explanation of what was wrong and how I fixed it.

With 2+ years of professional Flutter development, I have solved hundreds of real-world issues including null safety errors, state management bugs (GetX, Provider, BLoC), Firebase connectivity problems, UI rendering glitches, performance lags, and push notification failures.

What you get with every order: the fixed source code, a written summary of all bugs found and resolved, clean Dart code following best practices, and post-delivery support for 3 days.

I work fast. Most minor bug fixes are delivered within 24 hours. Drop me a message before ordering so I can confirm I can fix your specific issue I only accept orders I am 100% confident I can complete
