I will fix flutter app bugs, crashes and android errors
Flutter Mobile App Developer for iOS and Android
I design, build and improve Flutter apps for iOS and Android.
My work covers new MVPs, Figma-to-Flutter builds, existing-app fixes, Firebase and REST APIs, store releases and monetization with AdMob ...
About this Gig
Is your Flutter or Android app crashing, failing to build, or not working correctly?
I will diagnose and fix bugs in existing Flutter and native Android applications. I work with Flutter, Dart, Kotlin and Java projects, including clearly defined technical, integration and compatibility issues.
I can help with:
- Flutter and Dart errors
- Android crashes and runtime issues
- Gradle, dependency and SDK build errors
- Firebase authentication, database and notification problems
- REST API integration and data-loading errors
- UI, navigation and responsive-layout bugs
- Performance and device-compatibility issues
- Google Play build and release errors
- Supabase and data-storage problems
- FlutterFlow custom-code and exported-project issues
What you receive:
- Diagnosis of the reported problem
- Clean, maintainable code changes
- Testing of the affected functionality
- Updated source code
Packages are based on troubleshooting time rather than a guaranteed number of fixes, because issue complexity varies.
Please message me before ordering with the error details, screenshots or logs, technology used and source-code availability. I will review the issue and confirm the appropriate package.

FAQ
Should I contact you before ordering?
Yes. Please send the error details, screenshots or logs, technology used and a brief explanation of the expected behavior. I will review the issue and recommend the appropriate package.
How many bugs are included in each package?
Packages are based on working time, not a fixed number of bugs. A simple issue may take less than one hour, while a complex crash or build problem can require additional troubleshooting.
What do you need to begin?
I normally require the source code, steps to reproduce the issue, relevant error logs, expected behavior and any test credentials required for the affected feature. Share project access only through Fiverr-approved methods.
Do you fix both Flutter and native Android apps?
Yes. I work with Flutter and Dart applications as well as native Android projects using Kotlin, Java and Jetpack Compose.
Can you fix Firebase, Supabase or API integration issues?
Yes. I can troubleshoot authentication, databases, notifications, data storage, REST APIs and related integration problems when the required project access is available.
Is source code included?
Yes. Updated source code is included in every package. You must own the application or have authorization to modify its code.
Can you add new features?
Small corrections related to the reported issue may fit within a package. New screens, major features or unrelated improvements require a separate custom offer.
What counts as a revision?
A revision covers a reasonable correction related to the delivered fix. A new bug, new feature or unrelated request is outside the original scope.
