FAQ
Can you fix any Flutter bug?
I can handle most Flutter bugs, API issues, Firebase problems, build errors, and application logic issues. Complex problems may require additional hours after an initial review.
What do you need before starting?
Please provide the source code or repository access, a clear description of the issue, steps to reproduce it, error messages or screenshots, and any required test credentials.
Does one package mean one bug?
Packages are based on working time, not the number of bugs. Related issues can be handled within the included hours.
Can you fix backend or API issues too?
Yes. I can also investigate PHP backend, REST API, database, authentication, Redis, and integration issues when they affect the mobile app.
Do you provide source code after the fix?
Yes. Changes are made to your existing source code and the updated code is included in the delivery.
Should I contact you before ordering?
Yes, especially for crashes, build problems, API integrations, Firebase issues, or bugs that may involve backend changes. I can help confirm the right package first.
