Flutter Gym Diet App Build

I’ve already crafted every screen for a Gym-focused diet-food delivery app in Google AI Studio, so the visual direction is locked in. What I need now is a seasoned Flutter (or React Native) developer who can turn those static screens into a production-ready Android build.

Core scope
The app should mirror my UI exactly while delivering the full feature set: mobile OTP login, home and explore sections for diet plans, cart and subscription flows, user profile, daily tracking, an integrated admin panel connection, Firebase backend, push notifications, payment gateway, and—per my recent decision—a built-in referral program to reward users for bringing friends. Once complete, the APK and AAB must be ready for Play Store release.

What you’ll receive from me
• High-resolution UI screenshots and flow diagrams straight from Google AI Studio
• A clear feature-by-feature explanation and logic for each screen
• Prompt answers during development and Play Store submission

What I expect back
• Clean, maintainable Flutter or React Native source code
• Fully functional Android app tied to Firebase (Auth, Firestore/Realtime DB, Cloud Functions, FCM)
• Payment gateway wired and test-verified
• APK + AAB that pass Play Console checks
• Guidance during first-time upload so the listing goes live without hiccups

Nice-to-haves (for future phases) could include social media sign-in or in-app chat, but they aren’t required right now.

Preferred skill set
• Expert-level Flutter (Dart) or React Native
• Solid Firebase architecture know-how
• UI fidelity and responsive layout skills
• Prior experience launching apps on Google Play

Let’s start on a lean budget; I’m open to raising it once I see your approach and past work. Share relevant live apps, and outline your estimated timeline to get us from codebase to Play Store launch.
