I will fix flutter app bugs, crashes, and build errors
Flutter Developer Mobile Apps Firebase APIs
About this Gig
Is a bug, crash, or build error stopping your Flutter app? I will diagnose the root cause and implement a clean, tested fix for Android, iOS, or both.
I can help with Flutter UI and logic bugs, crashes and performance issues, Gradle or Android build errors, Xcode or iOS build failures, Firebase problems, REST API errors, state-management issues, and Kotlin, Java, or Swift native integrations.
Each package covers one agreed problem area with a clear investigation limit. You receive the updated source code, validation of the affected flow, and a concise explanation of what changed.
Send me the error, reproduction steps, target platform, Flutter version, and any useful logs or screenshots before ordering. I will review them and recommend the right scope.

FAQ
Can you fix any Flutter bug?
I can investigate Flutter UI, logic, Firebase, API, build, performance, and native-integration issues. Share the error and reproduction steps first so I can confirm the right package.
What counts as one issue?
One reproducible symptom or closely related problem with the same root cause. Unrelated errors, screens, platforms, or integrations may need separate scope.
Do you need my source code?
Usually, yes. A repository invite or project archive lets me investigate properly. If a service is involved, invite only the access needed and never share passwords or 2FA codes.
What counts as a revision?
A revision covers an adjustment to the agreed fix. A new defect, feature, or changed requirement is outside the original scope and can be quoted separately.
Do you need access to my source code?
Usually yes. You can share an archive through Fiverr or invite me to the repository. Service access should use limited collaborator permissions rather than passwords or 2FA codes.
What counts as a revision?
A revision corrects the delivered fix for the same agreed defect. A different bug, new feature, changed requirement, or new platform problem is a separate task.
