Add home screen widgets to Flutter apps for Android and iOS with native UI and shared data synchronization. \n \n Flutter communicates with native widgets via shared local storage (UserDefaults on iOS, SharedPreferences on Android) using the home_widget package; data flows from Flutter writes to native widget reads on OS trigger. \n iOS implementation uses Xcode, SwiftUI, and Widget Extension targets with App Groups capability; Android uses Android Studio with AppWidgetProvider, XML layouts, and
