About this Gig
Is your Flutter app crashing, showing UI bugs or failing to build?
I will investigate the cause and fix agreed issues in your existing Flutter app, with clear updates throughout the work.
I can help with:
- App crashes and runtime errors
- UI, layout and overflow issues
- Firebase Authentication and Firestore bugs
- REST API integration and data handling errors
- Android build, Gradle and dependency issues
- Navigation, validation and state management bugs
You will receive:
- Updated source code with the agreed fixes
- Testing of the affected functionality
- A brief summary of changes and testing
Each package covers a defined scope. Basic is for one minor bug, Standard for one agreed advanced issue, and Premium for up to three agreed related bugs in one app flow. New features and larger changes require a separate quote.
Please message me before ordering with your error logs, screenshots and steps to reproduce the issue. I will review the details and confirm the right package, scope and delivery time.

FAQ
Do I need to share my code?
Yes. Screenshots and error logs help with the initial review, but fixing the issue normally requires the relevant Flutter source code or repository access, along with steps to reproduce the problem.
How fast can you fix my issue?
Delivery depends on the issue and codebase. I review the details before confirming the package. Standard delivery is 2, 3 or 5 days. For urgent fixes, please message me first so I can confirm availability.
Can you fix API or Firebase problems?
Yes. I troubleshoot Flutter API integration and Firebase issues such as authentication, data fetching and configuration. Backend changes are included only when explicitly agreed after reviewing the issue. New backend features require a separate quote.
Is my code safe with you?
I keep your project confidential and request only the access needed for the agreed fix. Where possible, use private repository invitations, test accounts and limited permissions.
Can you fix App Store / Play Store errors?
Yes, I can fix publishing, signing, and build issues.
What do the package work hours cover?
The included work hours cover investigation, fixing, testing the affected functionality and a brief summary. We agree on issues that fit the package before ordering. Larger or uncertain issues require a custom quote.
