FAQ
Do I need to contact you before ordering?
Yes. Please message me first with the issue details so I can inspect the scope and recommend the correct package.
What do you need to start debugging?
Please provide the Flutter source code or repository access, steps to reproduce the issue, screenshots or video, error logs, and any required test credentials.
Can you fix both Android and iOS Flutter issues?
Yes. I can troubleshoot Flutter apps on Android and iOS. The required platform and issue must be confirmed before ordering.
What counts as a small bug?
A small bug is one isolated issue that can normally be diagnosed and fixed within one working hour. Complex or multiple related issues require a higher package.
Can you fix Firebase, API, or build errors?
Yes. I can fix Firebase, REST API, Android Gradle, CocoaPods, Xcode, and related Flutter build issues, depending on the agreed scope.
Can you also publish the fixed app?
Release support can be purchased separately. You must provide your own Google Play or Apple Developer account, and final approval remains controlled by Google or Apple.
