FAQ
Will I get the full source code after the project is finished?
Yes, 100%. You receive the complete, clean, well-commented Flutter source code, Git repo access, and all Firebase or API credentials on final delivery. You own everything with no restrictions.
Can one Flutter app really run on both Android and iOS?
Yes. Flutter uses a single Dart codebase that compiles to native binaries on both platforms, giving near-identical performance and UI across Android and iOS the main reason Flutter beats building two separate native apps.
Can you integrate Firebase, REST APIs, payments, and third-party services?
Absolutely. I regularly build apps with Firebase Auth, Firestore, Cloud Functions, REST and GraphQL APIs, Stripe, PayPal, Razorpay payments, Google Maps, push notifications, and social logins. Message me with your requirements and I will confirm scope before we start.
Will you publish my app to the Google Play Store and Apple App Store?
Yes, included in the Premium package. You will need an active Google Play Developer account ($25 one-time) and Apple Developer account ($99/year) in your name. I handle the full build configuration, store listing assets, and submission process.
What if I need changes or run into bugs after delivery?
Every package includes revisions and the Premium package comes with 30 days of free post-launch bug-fix support. After that I offer affordable maintenance retainers so your app is never abandoned after handoff.
