Fix, Improve & Optimize Your Existing Flutter App
Is your Flutter app crashing, showing bugs, failing to connect to an API, or not behaving the way it should?
I’ll inspect your existing Flutter project, identify the root cause and implement the agreed fixes or improvements.
Whether it's a UI issue, Firebase problem, API failure, build error, state-management bug or performance problem, I can help get your application back on track.
Project Diagnosis
I’ll review the relevant part of your Flutter project and identify the likely cause of the issue.
Targeted Fixes
I’ll implement the agreed fixes without unnecessarily rewriting working parts of your application.
Testing
I’ll test the affected functionality and verify that the implemented fix works as expected.
Clean Code Changes
Changes will be kept organized and maintainable so your project remains easier to work on.
Clear Handover
I’ll explain what was fixed and highlight anything that may require additional work.
My process
01 — Understand the Problem
You describe the issue and share the relevant project/error details.
02 — Inspect
I investigate the affected code, dependencies, API/Firebase configuration or UI.
03 — Fix
I implement the agreed solution.
04 — Test
I verify the affected flow and check for obvious regressions.
05 — Deliver
You receive the updated project and a concise summary of the changes.
What I need from you
Flutter project/source code
Clear description of the issue
Error messages or screenshots/videos when available
Steps to reproduce the problem
API/Firebase details if relevant
Figma/design reference if the issue is UI-related
Important: Please message me before purchasing if your application has multiple unrelated issues. I'll review the scope and recommend the most suitable service or a custom project.
