FAQ
What issues are you facing in your Flutter app or Go backend?
✅ Please describe the specific bugs, errors, or crashes in your Flutter app or Go backend. If possible, provide error messages or screenshots to speed up debugging.
Do you have error logs or screenshots of the bugs?
✅ Yes, logs and screenshots help identify and fix issues faster. If you don’t have logs, I can guide you on how to collect them from Android Studio, Xcode, or your backend server.
Are you using Firebase, REST API, or GraphQL for backend services?
✅ Let me know whether your app connects to Firebase, a Go-powered REST API, or GraphQL backend so I can check the server connections, authentication, and database interactions.
Do you need Play Store or App Store submission assistance?
✅ Yes, I can help you publish or update your app on Google Play Store & Apple App Store, ensuring it meets all compliance requirements. (This is available in my Premium Package or as an Extra Service.)
Should I work on your developer account or a GitHub repository?
✅ I can work directly on your developer account (Google Play Console, App Store Connect) or via GitHub, Bitbucket, or GitLab. If you prefer a ZIP file or Google Drive, that works too.
Will my code remain secure?
✅ Absolutely! Your project’s security and confidentiality are my top priority. I won’t share or reuse any code, and I can sign an NDA (Non-Disclosure Agreement) if required.
What if my app has major issues beyond bug fixing?
✅ If your app requires new feature development or complete redesign, we can discuss a custom offer based on your needs.
How long does it take to fix bugs?
✅ Minor bugs take a few hours to 1 day, while complex issues may take 2-5 days, depending on the severity. For critical production issues, I offer priority support in the Premium Package.
What if the issue persists after the fix?
✅ I provide free revisions until the bug is completely fixed! If additional problems arise, I will assist you at a discounted rate.
