FAQ
How do I share my code with you?
GitHub repository is preferred. If you do not have one, share a zip file of your Flutter project. I will review it and get back to you within hours with a diagnosis.
Can you fix bugs without full source code access?
For most bugs I need the full project. For specific error messages or crash logs, sometimes I can diagnose from screenshots or error output alone. Message me first and I will tell you what I need.
What if the bug is not fixed after delivery?
I offer revisions on every package. If the bug persists after my fix, I will resolve it within the revision window at no extra cost. I do not close an order until your code works.
Can you fix Firebase or third party integration errors?
Yes — Firebase Auth, Firestore, FCM, Google Maps API, REST API, Cloudinary, Stripe integration errors. These are exactly the tools I use in my own production apps daily.
Do you fix iOS Flutter bugs too?
I fix Flutter Dart code level bugs that affect both Android and iOS. For iOS specific build or App Store issues, you will need a Mac environment - I can fix the code side, not the iOS build environment itself.
