I need a straightforward cross-platform app that simply wraps my existing website with WebView, built in the latest stable Flutter. The app should open the supplied URL, show a subtle loading indicator, support in-app back navigation, launch external links in the device browser, and display friendly screens for errors or when no connection is available. No user authentication is required. Brand basics are ready, so please wire in the provided app icon, splash screen and a light touch of theming to keep everything on brand. When you are done, I expect production-ready builds for both stores—Android (AAB/APK) and iOS (IPA or Xcode project)—plus clear build instructions so I can reproduce the binaries locally. Deliverables • Complete Flutter source code, clearly organised • Android release build (AAB/APK) • iOS release build (IPA or full Xcode project) • Read-me with step-by-step build and store-submission guidance When you reply, include a short note on your Flutter experience, links to any similar WebView wrapper apps you’ve shipped, and whether you prefer hourly or fixed-price for work at this scale.
