FAQ
What information do you need to fix my Flutter app?
Please share your Flutter project source code (or the relevant files), a description of the bug, any error messages or crash logs, and steps to reproduce the problem. If you're unsure, just message me and I'll guide you through what's needed.
Can you fix bugs without having the full source code?
In most cases, I need at least the relevant portion of the source code to properly identify and fix the issue. For Play Store or App Store rejections, an APK or IPA along with the rejection reason is usually sufficient. Please message me first so we can discuss your situation.
How long will it take to fix my app's bugs?
Most simple bug fixes are delivered within 24 hours. For complex issues involving multiple bugs, performance problems, or store rejections, delivery is typically 2–4 days. I always communicate timelines upfront and keep you updated throughout the process.
What if the bug comes back after delivery?
All packages include free post-delivery support (3–14 days depending on the package). If the same issue returns within the support period, I'll fix it at no additional charge. Your satisfaction is my top priority.
Can you also add new features or improve performance while fixing bugs?
Yes! The Premium package includes performance optimization alongside bug fixing. For new feature development or major improvements, I recommend checking my main Flutter development gig or messaging me for a custom offer tailored to your project needs.
