About this Gig

Is your Flutter app crashing, behaving incorrectly, or failing in an existing user flow?


I will diagnose and fix focused bugs in existing Flutter applications.


What I can help with:

Reproducible crashes and runtime errors

Incorrect app logic and state-management behavior

JSON parsing and existing API integration failures

Existing Firebase, SQLite, or dependency-related issues

Android and iOS issues in an agreed flow


What you receive:

Clean code changes for the agreed issue

A short summary of the fix

Testing of the agreed flow

One revision within scope


Please share the problem, steps to reproduce, expected result, logs or screenshots, Flutter version, and project access needed to reproduce the issue. New features, large SDK upgrades, backend development, and unrelated bugs require a custom offer.
