About this Gig
Is your Flutter app crashing, failing to build, or showing Firebase and API errors?
I help repair existing Flutter apps with a clear process: reproduce the issue, identify the cause, make a focused code change, and test the agreed flow.
I can help with:
- Flutter bugs, crashes and UI issues
- Firebase Authentication and Firestore errors
- REST API, JSON and backend connection issues
- Android Gradle or iOS Xcode build blockers
You receive updated source code, a change summary and test evidence for the agreed platform.
Basic: one pre-assessed minor bug.
Standard: one existing Firebase or API flow.
Premium: one Android or iOS build blocker plus up to two agreed minor bugs.
Message me before ordering with your error logs, Flutter version, reproduction steps and project access so I can confirm scope and timing.
Packages cover existing code and the agreed platform. New features, major upgrades, store submission and additional issues need a separate offer.

FAQ
Which package should I choose?
Basic covers one pre-assessed minor bug. Standard covers one existing Firebase or API flow. Premium covers one Android or iOS build blocker plus up to two agreed minor bugs. Send the issue first so I can confirm the right scope.
What do you need before starting?
Please provide your Flutter version, target platform, error logs, steps to reproduce, expected behavior and source-code access. Share any relevant setup instructions and test-account details through the order requirements.
Can you repair Android and iOS Flutter apps?
Yes. Each package covers the agreed platform and available test environment. Please confirm whether the issue affects Android, iOS or both. Work on a second platform is scoped separately unless explicitly included in your offer.
Can you fix Firebase and REST API issues?
I can repair agreed issues in existing Firebase Authentication, Firestore and REST API flows. Please explain the failing action and provide relevant logs and setup details. New integrations and unavailable backend changes require separate scope.
Will I receive the updated source code?
Yes. Every package includes the updated source code for the agreed repair, a short change summary and test evidence for the affected flow on the agreed platform.
What is included in a revision?
A revision addresses corrections to the original agreed repair. New features, unrelated bugs, additional platforms or changed requirements need a separate offer. Basic and Standard include one revision; Premium includes two.
Do you offer urgent fixes or ongoing maintenance?
Please message me with the issue and deadline before ordering an urgent repair. I will confirm feasibility and availability. Ongoing maintenance and future feature work can be arranged through a separately scoped offer.
Are new features or app store submission included?
These packages cover repairs to existing code. New features, major upgrades, full rebuilds and app store submission are quoted separately. Store approval is controlled by Apple or Google and is not part of the repair deliverable.
