FAQ
What do you need from me to get started?
To start fixing your bug, I need: - The project source code (Flutter project folder) - A description of the issue - Error screenshots or screen recording - Any error logs (if available) - API keys or backend access (only if the bug is related to backend)
Will you fix both Android and iOS issues?
Yes! I can debug and fix issues for both Android and iOS, including platform-specific build errors, crashes, and dependency conflicts.
How do you handle complex issues?
For complex bugs or multiple issues, I will first analyze the code, identify the root cause, and then share the estimated time and cost before starting.
Can you fix Firebase-related issues?
Absolutely. I can resolve errors related to Firebase Auth, Firestore, Storage, Cloud Messaging, Functions, and other integrations.
Will you explain the issue after fixing it?
Yes, if you want, I can explain the bug, what caused it, and how it was fixed—so you can avoid the same issue in the future.
Do you provide long-term support?
Yes. After delivering the fix, I provide free support for the same issue for a limited time. Any new issues can be handled with a new order or gig extra.
Why should I contact you before ordering?
Contacting me first helps ensure that: - I fully understand the issue - You choose the correct package - I can deliver quickly and efficiently It protects both of us from misunderstandings.
Can you work on an existing live app?
Yes, I can work on your existing live Flutter app, provided you give the necessary access or updated build.
