Über diesen Service
Is your Flutter app blocked by a crash, UI bug, Android build error, or store release issue? I help production Flutter apps get back to a working build without rewriting the app blindly.
I can debug and fix:
- Flutter runtime crashes, UI/layout bugs, state/API issues
- Android/Kotlin/Gradle errors, AGP/Kotlin version conflicts, namespace/JVM target issues
- Firebase setup, platform channels, AndroidManifest/permissions, plugin native integration
- AAB/APK signing, Play Console warnings, App Store/TestFlight release blockers
- Dependency/version conflicts after Flutter, Gradle, or package upgrades
My process:
1. Review your error logs, reproduction steps, and project setup.
2. Find the real root cause, not just the last visible error message.
3. Apply the fix in your existing architecture.
4. Share what changed and how to verify it.
Please contact me before ordering so I can confirm the issue scope, package, and delivery time. All communication and orders stay on Fiverr.

FAQ
Can you fix bugs in an existing Flutter project?
Yes. I can work with an existing Flutter codebase if you provide source code access, reproduction steps, screenshots or videos, logs, and expected behavior.
Can you fix Android and iOS build errors?
Yes. I can debug Flutter, Gradle, CocoaPods, Xcode, Firebase, package dependency, and release configuration issues.
What do you need to start debugging?
Please send the source code, bug description, steps to reproduce, logs, screenshots or video, target platform, and any required test credentials.
Can you optimize Flutter app performance too?
Yes. I can optimize slow screens, janky scrolling, startup time, API delays, memory leaks, heavy widgets, and general app stability when included in the selected package.
Can you help with App Store or Google Play deployment issues?
Yes. I can fix Flutter release blockers such as AAB/APK, app signing, keystore, certificates, provisioning profiles, TestFlight upload and Google Play testing tracks. App approval still depends on Apple/Google review policies.
Can you fix Android native Kotlin issues inside a Flutter app?
Yes. I can fix Android native issues inside Flutter apps, including Kotlin code, Gradle config, AndroidManifest, Firebase setup, platform channels, AAB/APK signing, and Play Console build blockers when they affect your Flutter app.
