Over deze dienst
Is your Flutter app crashing, failing to build, or behaving unexpectedly? I will diagnose and fix the issue cleanly so your app works reliably on Android, iOS, or web.
I can help with:
- Runtime errors, crashes, and exceptions
- Android Gradle and iOS/Xcode build issues
- Firebase, Firestore, authentication, and notification bugs
- REST API, JSON parsing, and backend integration errors
- UI overflow, responsiveness, navigation, and state-management issues
- Package conflicts, deprecated code, and Flutter upgrades
- Performance problems, freezes, and slow screens
- App Store or Play Store build and release errors
What you receive:
- A tested and maintainable fix
- Clean changes without unnecessary rewrites
- A clear explanation of the cause and solution
- Updated source code
- Post-delivery support for the completed fix
I work with existing Flutter projects using GetX, Provider, Riverpod, BLoC, Firebase, REST APIs, and native Android/iOS integrations.
For complex, recurring, or multiple issues, please message me before ordering so I can review the scope and recommend the correct package.

Veelgestelde vragen
Can you fix any Flutter bug?
I can fix most Flutter issues, including crashes, UI problems, Firebase errors, API integration issues, state-management bugs, package conflicts, and Android or iOS build failures. Complex issues should be reviewed before ordering.
Should I contact you before placing an order?
You can order the Basic package directly for a clearly defined small issue. Please contact me first when the app has multiple bugs, an unclear problem, a recurring crash, or a complex build issue.
What do you need to start working?
I need the Flutter source code, a clear description of the problem, steps to reproduce it, and any available screenshots, videos, logs, or error messages.
Will you test the fix before delivery?
Yes. I will reproduce the issue where possible, implement the fix, and test the affected feature before delivering the updated source code.
Can you fix Android Gradle build errors?
Yes. I can troubleshoot Gradle, Kotlin, Java, Android SDK, dependency, signing, manifest, and Flutter package compatibility issues.
Can you fix iOS and Xcode build problems?
Yes, provided the required Apple project files, certificates, provisioning information, or relevant access are available. Some App Store or signing issues may require cooperation from the account owner.
Can you fix Firebase and API issues?
Yes. I work with Firebase Authentication, Firestore, Cloud Messaging, Storage, REST APIs, JSON parsing, authentication tokens, and backend integration errors.
Will you rewrite my entire application?
No. This gig focuses on targeted debugging and bug fixing. Large rewrites, new modules, major redesigns, or substantial feature development require a custom offer.
Do you provide support after delivery?
Yes. Support is included for the specific issue completed in the order. New or unrelated bugs are handled separately.
Is my source code kept confidential?
Yes. Your project files and business information will only be used to complete the order and will not be shared or reused.
