FAQ
What do you need to fix my bug or optimize my app?
I will need access to your Flutter project repository (GitHub/GitLab or zip file) and a clear description or screenshot of the issue.
Do you test fixes on both iOS and Android?
Yes! I test and resolve issues across both platforms to ensure full cross-platform compatibility.
What if my bug requires fixing backend/Firebase code?
I specialize in Firebase Authentication, Cloud Firestore, and REST API integrations. If the bug involves backend data or API connections, I can resolve both frontend and backend issues.
How do I share my Flutter project files with you?
You can share access via a GitHub/GitLab repository link, or upload a ZIP file of your codebase directly in the order requirements once you place the order.
What if the bug is not fixed after delivery?
All packages include revisions! I test all code thoroughly before delivery, but if any issue persists, I will continue refining it until it works seamlessly on your setup.
