I need a very lightweight Flutter application that runs smoothly on both Android and iOS. It is just a single screen whose entire purpose is user interaction—no data storage, or database connections in the background. Here’s the flow I have in mind: the screen loads first a splash screen instantly, then presents main screen the user with a clean interactive element (for example, a button, toggle, or other simple control), and reacts locally to that input with an on-screen change. All logic stays on the device; there is absolutely no back-end integration required. What I expect from you • Clean, well-commented code structured for easy hand-off • A runnable project that opens without errors in both Android Studio and Xcode • Final build artifacts: one signed APK and one IPA (TestFlight-ready is fine)
