Native Platform Views for mobile and beyond
summary
Builds a native camera preview embedded in Flutter using SwiftUI via UIHostingController on iOS and macOS and a Kotlin native view using the camera-view library (Camera2) on Android, controlled over method channels to take pictures and switch lenses. Renders natively at full device frame rate, outperforming the stock Flutter camera plugin. Uses Android composition modes (virtual display, hybrid, texture layer hybrid composition) and notes Flutter 3.3 bugs; macOS works from the master channel but has missing gesture pass-through, resize threading bugs and platform-view-overlays and scrolling with many views causes performance and ad-attribution issues.
