I will fix flutter app bugs firebase issues crashes and API errors
About this Gig
Is your Flutter app crashing, showing errors, or not working correctly?
I will identify and fix bugs in your Flutter application, Firebase integration, APIs, UI, authentication, database operations, and Android build setup.
I can help with:
- Flutter and Dart errors
- App crashes and build failures
- Firebase Authentication issues
- Firestore and Realtime Database bugs
- API integration and response errors
- UI layout and responsive design problems
- Navigation and state-management issues
- Notifications, login, signup, and form errors
- Performance problems and code cleanup
You will receive clean fixes, updated source code, and a clear explanation of the work completed.
Please send the error details, screenshots, source code, and expected behaviour before ordering. For complex issues or multiple bugs, message me first so I can confirm the correct package, price, and delivery time.
Important: This Gig is for fixing existing Flutter applications. New features, complete app development, publishing, and major redesigns require a custom offer.

FAQ
What information do you need to start?
I need your Flutter source code, screenshots or screen recordings of the issue, error logs if available, and a clear explanation of the expected behaviour.
Can you fix Firebase issues?
Yes. I can work on Firebase Authentication, Firestore, Realtime Database, Cloud Messaging, configuration errors, permissions, and common integration problems.
Can you fix Android build errors?
Yes. I can fix many Gradle, dependency, SDK, package, signing-configuration, and Flutter build errors. Please share the complete error log before ordering.
Do you develop new features?
Small changes may be possible through a custom offer. Large features or complete application development are not included in the standard bug-fixing packages.
Will you provide the updated source code?
Yes. After completing the work, I will provide the updated source code or clearly identified modified files, depending on the project and agreed scope.
What counts as one bug?
One bug means one clearly defined issue with a single expected result. Multiple unrelated errors or issues across several screens may require a larger package or custom offer.
Do you guarantee Play Store approval?
No. I can fix technical issues and prepare the app, but final approval is controlled by Google Play and depends on its policies and review process.
Should I contact you before placing an order?
Yes, especially for crashes, Firebase problems, API errors, legacy code, or multiple bugs. This helps confirm the correct scope and avoids delays.
