## Overview

This is a Flutter client for automating login to East China Jiaotong University’s campus network. The intended user flow is to manage saved accounts, authenticate through the campus portal, and inspect or log out online devices; Windows also supports launch-at-startup. The tree shows a single Dart entry file, while the README documents these product capabilities. Native Windows startup handling and Android method-channel behavior are visible in sampled source; Dart-side wiring and the portal/device implementation were not sampled, so those links are limited to documented behavior.

Main entry points: [`lib/main.dart`](https://github.com/star7-github/login-ecjtu-2/blob/main/lib/main.dart) (Campus login app), [`android/app/src/main/java/com/star7/loginecjtu2/MainActivity.java`](https://github.com/star7-github/login-ecjtu-2/blob/main/android/app/src/main/java/com/star7/loginecjtu2/MainActivity.java) (Android Wi-Fi channel), [`windows/runner/flutter_window.cpp`](https://github.com/star7-github/login-ecjtu-2/blob/main/windows/runner/flutter_window.cpp) (Startup preference)
