I have an existing web application that works well in the browser but I’m ready to give users a truly native experience on both iOS and Android. I will provide the current web app, the user flows that matter most on mobile, and all design assets. Your task is to rebuild the product in Flutter so it installs, launches, and feels like a platform-specific app rather than a wrapped website. The top priority is rock-solid, smooth native navigation (tab bars, back-stack, deep links, the whole lot). Beyond that, I still need the other mobile must-haves—offline use when a connection drops and push notifications—to be wired in cleanly, but navigation is the yard-stick I’ll judge first. I’m comfortable with Flutter for its single codebase and native-level performance, so please stay within that stack. Any supporting libraries are fine as long as they are well-maintained and don’t bloat the build. Deliverables I expect: • Flutter codebase with clear structure and comments • Release-ready builds for the App Store and Google Play (including all icons, splash screens, and store assets) • Instructions to run, test, and build the project locally • Demonstration that navigation, offline caching, and push notifications perform flawlessly on real devices If you’ve shipped Flutter apps before and can point to them, that will help me decide quickly.

Hello, I can rebuild your web app as a truly native-feeling Flutter app for iOS and Android. Navigation comes first: bottom tabs that keep their state, a proper back-stack and deep links using go_router. I'll add offline caching with local storage (Hive/Drift) that syncs on reconnect, plus Firebase push notifications, using clean architecture and well-maintained packages to keep the build lean. Deliverables: commented source, release-ready builds with icons, splash screens and store assets, run/build instructions, and a real-device demo of navigation, offline mode and push. Is your web app backed by REST or GraphQL APIs that I can reuse? Regards, Harsh Thoriya

Navigation is exactly where most web-to-Flutter ports fall apart, so I'd build that layer first: a go_router shell with persistent tab bars, per-tab back-stacks, and deep link handling wired to iOS Universal Links and Android App Links, tested on real devices before any screen work begins. Next, I'd map your priority user flows to a clean feature-based structure with a local cache (Drift/Hive) plus a sync queue so the app stays usable offline, then add FCM/APNs push with proper cold-start routing. Finally, icons, splash, store assets, signed builds, TestFlight and Play internal testing. I've shipped 80+ apps since 2008 across Flutter, Swift and Kotlin, including offline-capable clients backed by Node/Postgres APIs. Which backend does the web app currently call — REST, GraphQL, or Supabase?

Hey! A Flutter app can look right and still feel wrong if navigation, tab state, and back behavior are not designed properly for mobile. I’d build the navigation structure first so the app feels natural on both iOS and Android rather than simply reproducing the existing web screens. I can work from your existing web app, mobile flows and design assets while keeping the Flutter codebase clean, modular, and lightweight. I will also integrate offline caching and push notifications around the core flows, test on real iOS and Android devices and handle release builds, store assets, and local setup instructions. I have worked on similar mobile application requirements and can show relevant examples in chat so you can review the quality and approach.

I can rebuild your existing web application in Flutter as a genuine mobile experience—not a web wrapper—with navigation and performance treated as the highest priority. I’ll structure the app around Flutter’s native navigation capabilities, implementing a reliable tab/navigation hierarchy, back-stack behavior, deep links and state preservation. I’ll keep platform-specific behavior where needed so the experience feels natural on both iOS and Android. The implementation will also include: • Clean, modular Flutter architecture with maintainable code • Offline caching and sensible reconnection/sync handling • Push notifications for iOS and Android • REST/API integration with your existing backend • Proper loading, error and empty states • App icons, splash screens and required store configuration • Real-device testing across current iOS and Android devices • Release-ready App Store and Google Play builds • Clear setup, testing and build documentation I have extensive Flutter, native iOS and Android experience and have worked on production applications involving APIs, Firebase, notifications, authentication and offline/state management. I also have experience submitting 50+ apps to the App Store and getting them approved. Once you provide the web app, mobile user flows and design assets, I can map the existing functionality into a clean Flutter architecture and provide a milestone-based implementation plan.

Hi, Your goal to transform a web app into a truly native Flutter experience with robust navigation and offline capabilities aligns with a solid understanding of platform-specific user expectations. The main technical risk is ensuring the navigation stack behaves seamlessly across iOS and Android while maintaining offline reliability and push notification responsiveness. While my core experience centers on backend AI systems and scalable architectures, I approach systems by separating concerns such as navigation logic, offline data layers, and notification handling to ensure modularity and testability. This separation helps manage complexity and allows for incremental validation of critical flows. I’d validate navigation stack integrity early with real-device testing and design offline caching strategies that gracefully handle network transitions. Ensuring push notifications are integrated cleanly without bloating the build will also be key for performance. I can start by outlining a clean architecture for navigation and offline caching layers tailored to your user flows and then review integration points for notifications. Thanks, Clifton

Hi, I’ve worked on converting web apps to Flutter before, focusing on delivering a smooth, native experience for both iOS and Android. Given your emphasis on navigation and offline capabilities, I estimate around 4-6 weeks for a polished build, ensuring everything aligns with your requirements. To clarify the scope, do you have existing user flows or design guidelines for mobile in mind? Also, are there specific libraries you prefer for push notifications and offline caching, or should I suggest options that fit well with Flutter? For navigation, I’d structure the app to leverage Flutter’s capabilities for seamless tab bars and deep linking. Offline caching will be designed to ensure users can access the app without a connection, while push notifications will be integrated following best practices for both platforms. I have experience with similar projects and can ensure a structured codebase with clear documentation. Happy to discuss the current setup and take it from there. Best regards, Mohammad

Dear Client, I read "Convert Web App to Flutter" carefully and understand you want a single Flutter codebase that runs smoothly on both Android and iOS. My hands-on experience with Mobile App Development, iPhone, iOS Development, Flutter, App Development aligns directly with what you need. I've shipped Flutter apps from scratch to store launch — clean architecture, smooth animations, native-feeling UI and solid API integrations — that stay easy to maintain as features grow. A few quick questions to get us started: 1. Do you need Android, iOS, or both from day one? 2. Are UI designs ready, or should I design the screens as well? 3. Is there an existing backend/API, or should I build that too? Thanks & Regards, Deepak
