## Overview

This is an otherwise uncustomized Flutter starter app. The README describes no product-specific features, and the Dart entrypoint source was not included, so the graph focuses on the available platform launch shells and their handoff to the shared app; it cannot describe the app’s screens or behavior.

Main entry points: [`lib/main.dart`](https://github.com/kourae/flutter-activity/blob/main/lib/main.dart) (Flutter app), [`linux/runner/my_application.cc`](https://github.com/kourae/flutter-activity/blob/main/linux/runner/my_application.cc) (Linux host), [`windows/runner/main.cpp`](https://github.com/kourae/flutter-activity/blob/main/windows/runner/main.cpp) (Windows host), [`macos/Runner/MainFlutterWindow.swift`](https://github.com/kourae/flutter-activity/blob/main/macos/Runner/MainFlutterWindow.swift) (macOS host)
