## Overview

This is a minimal Flutter starter application, not a documented domain product. Its user workflow is to launch the app on a supported platform and render the Flutter/Dart application. The sampled native code shows platform startup and view creation, but the Dart sources were not sampled, so their internal wiring and UI behavior cannot be described reliably.

Main entry points: [`windows/runner/main.cpp`](https://github.com/subhamdangol/demo/blob/master/windows/runner/main.cpp) (Windows host), [`linux/runner/my_application.cc`](https://github.com/subhamdangol/demo/blob/master/linux/runner/my_application.cc) (Linux host), [`ios/Runner/AppDelegate.swift`](https://github.com/subhamdangol/demo/blob/master/ios/Runner/AppDelegate.swift) (iOS host), [`macos/Runner/MainFlutterWindow.swift`](https://github.com/subhamdangol/demo/blob/master/macos/Runner/MainFlutterWindow.swift) (macOS host)
