I’m building a cross-platform utility application and need an experienced Flutter developer who can take it from design files right through to App Store and Play Store submission. The core build will run from a single Flutter code-base and must deliver a smooth, native-feeling experience on both Android and iOS. Key functionality • Secure user authentication (email / password and token refresh). • Continuous data syncing with a backend (you’re free to propose REST, GraphQL, or Firebase as long as it stays reliable offline and online). • Configurable push notifications that can be triggered from the server side as well as locally. You’ll handle UI implementation, state management, integration of the chosen backend, and basic production-ready hardening (error handling, logging, build flavors for staging / production). Clean, well-commented Dart code is essential because I’ll be maintaining the project afterward. Deliverables 1. Complete Flutter source code in a private Git repository. 2. Build-ready Android (AAB) and iOS (IPA/TestFlight) packages. 3. Short README covering environment setup, key libraries, and how to run tests. 4. One-hour hand-off call to walk through the architecture. If you have shipped at least five Flutter apps that uses auth, background sync, and push notifications, I’d love to see it. Let me know your estimated timeline and any questions you may have about the workload or preferred tooling.

Hello, I can take your Flutter app from design files to full App Store and Play Store release using a single, clean codebase with native-level performance on both platforms. I’ve shipped multiple Flutter apps with secure auth, background/online sync, and server-driven + local push notifications, using scalable architectures. I’ll handle UI implementation, state management, backend integration, error handling, and proper build flavors, with well-commented, maintainable Dart code. You’ll get build-ready AAB/IPA, a clear README, and a smooth hand-off call so you can confidently maintain and extend the app. Quick questions: do you have a preferred backend (Firebase vs REST/GraphQL), and should offline sync be full-featured or basic cache-and-retry?

Hi, This sounds like a good, focused Flutter build, and I’m comfortable taking it end to end—from Figma designs to Play Store and App Store submission. I can help you build a smooth, native-feeling app from a single Flutter codebase for both Android and iOS. The app will cover secure authentication, reliable data syncing (offline and online), and configurable push notifications. I’ll keep the Dart code clean, well-structured, and well-commented so it’s easy for you to maintain after handover. For the backend, I’m flexible—Firebase or a REST-based setup both work well depending on your sync and notification needs, and I’m happy to recommend what fits best once we discuss usage patterns. I’ll also handle error handling, logging, and proper build flavors for staging and production. You’ll get the full source code in a private repo, build-ready Android and iOS packages, a clear README, and a hand-off call to walk through the architecture and decisions. Lets connect over chat so we could discuss the timeline and estimate.

Hi there, This is exactly the kind of Flutter project I specialize in—taking a product cleanly from design files to live App Store and Play Store releases using a single, well-architected codebase. I’ve shipped multiple production Flutter apps on both Android and iOS that include secure authentication, background data sync, and push notifications, so I’m very comfortable with the full lifecycle you’re describing. My focus is always on native-feeling UX, predictable state management, and maintainable Dart code that another developer can confidently take over. For the backend layer, I’m happy to recommend and implement the best fit based on your priorities—Firebase (Auth, Firestore, FCM) for speed and reliability, or a REST/GraphQL API if you prefer more control. Offline-first syncing, token refresh, and resilient error handling are things I build in from day one, not bolt on later. On the Flutter side, I’ll handle: • Pixel-accurate UI from your designs • Clean state management (Riverpod/BLoC, depending on preference) • Push notifications (local + server-triggered) • Logging, error handling, and build flavors for staging/production • Store-ready builds (AAB + TestFlight/IPA) and submission support I can also provide examples of Flutter apps I’ve shipped with auth, background sync, and notifications. Happy to discuss timeline, tooling preferences, and any edge cases you’re anticipating.

I’ve delivered multiple cross-platform Flutter applications where a single codebase powers a smooth, native-feeling experience on both Android and iOS, with a clear focus on maintainability and long-term scalability. I’ll take full ownership of translating your designs into a polished Flutter UI, selecting a reliable backend approach (REST/GraphQL or Firebase, based on your priorities), and implementing secure authentication with proper token handling and refresh logic. Data syncing will be built with offline-first behavior in mind so the app remains usable even with intermittent connectivity. Push notifications will be configurable and handled cleanly, supporting both server-triggered and local notifications without impacting performance or battery life. From an engineering standpoint - I’ll use a proven state management approach, add structured error handling and logging, and set up build flavors for staging and production. The Dart codebase will be clean, well-commented, and easy for you to extend or maintain after handover. Let's connect for further discussion! Thanks Saurabh
