Flutter窗口跟踪插件win_tracker的使用

win_tracker 是一个用于在 Flutter 应用中跟踪和管理窗口的插件。它允许你监听窗口的创建、销毁、激活和移动等事件，并且可以在多个平台上使用。以下是如何使用 win_tracker 插件的基本步骤：

1. 添加依赖

首先，你需要在 pubspec.yaml 文件中添加 win_tracker 插件的依赖：

dependencies:
  flutter:
    sdk: flutter
  win_tracker: ^1.0.0  # 请使用最新版本

然后运行 flutter pub get 来获取依赖。

2. 导入插件

在你的 Dart 文件中导入 win_tracker 插件：

import 'package:win_tracker/win_tracker.dart';

3. 初始化 WinTracker

在使用 WinTracker 之前，你需要初始化它。通常可以在 main 函数中进行初始化：

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await WinTracker.initialize();
  runApp(MyApp());
}

4. 监听窗口事件

你可以使用 WinTracker 来监听窗口的各种事件，例如窗口创建、销毁、激活、移动等。

class MyApp extends StatefulWidget {
  [@override](/user/override)
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  [@override](/user/override)
  void initState() {
    super.initState();
    
    // 监听窗口创建事件
    WinTracker.onWindowCreated.listen((window) {
      print('Window created: ${window.id}');
    });

    // 监听窗口销毁事件
    WinTracker.onWindowDestroyed.listen((window) {
      print('Window destroyed: ${window.id}');
    });

    // 监听窗口激活事件
    WinTracker.onWindowActivated.listen((window) {
      print('Window activated: ${window.id}');
    });

    // 监听窗口移动事件
    WinTracker.onWindowMoved.listen((window) {
      print('Window moved: ${window.id}');
    });
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('WinTracker Example'),
        ),
        body: Center(
          child: Text('Hello, WinTracker!'),
        ),
      ),
    );
  }
}

5. 获取当前窗口信息

你可以使用 WinTracker 获取当前窗口的信息：

void printCurrentWindowInfo() async {
  final window = await WinTracker.getCurrentWindow();
  print('Current window ID: ${window.id}');
  print('Current window title: ${window.title}');
  print('Current window position: ${window.position}');
  print('Current window size: ${window.size}');
}

6. 操作窗口

WinTracker 还允许你对窗口进行一些操作，例如关闭窗口、最小化窗口等。

void closeCurrentWindow() async {
  final window = await WinTracker.getCurrentWindow();
  window.close();
}

void minimizeCurrentWindow() async {
  final window = await WinTracker.getCurrentWindow();
  window.minimize();
}

7. 处理多个窗口

如果你的应用有多个窗口，你可以使用 WinTracker 来管理这些窗口。

void printAllWindows() async {
  final windows = await WinTracker.getAllWindows();
  for (var window in windows) {
    print('Window ID: ${window.id}, Title: ${window.title}');
  }
}

8. 注意事项

• win_tracker 插件可能在不同的平台上有不同的支持程度。请确保你使用的平台是支持的。
• 在使用窗口操作时，确保你有相应的权限。

9. 示例代码

以下是一个完整的示例代码，展示了如何使用 win_tracker 插件：

import 'package:flutter/material.dart';
import 'package:win_tracker/win_tracker.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await WinTracker.initialize();
  runApp(MyApp());
}

class MyApp extends StatefulWidget {
  [@override](/user/override)
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  [@override](/user/override)
  void initState() {
    super.initState();

    WinTracker.onWindowCreated.listen((window) {
      print('Window created: ${window.id}');
    });

    WinTracker.onWindowDestroyed.listen((window) {
      print('Window destroyed: ${window.id}');
    });

    WinTracker.onWindowActivated.listen((window) {
      print('Window activated: ${window.id}');
    });

    WinTracker.onWindowMoved.listen((window) {
      print('Window moved: ${window.id}');
    });
  }

  void printCurrentWindowInfo() async {
    final window = await WinTracker.getCurrentWindow();
    print('Current window ID: ${window.id}');
    print('Current window title: ${window.title}');
    print('Current window position: ${window.position}');
    print('Current window size: ${window.size}');
  }

  void closeCurrentWindow() async {
    final window = await WinTracker.getCurrentWindow();
    window.close();
  }

  void minimizeCurrentWindow() async {
    final window = await WinTracker.getCurrentWindow();
    window.minimize();
  }

  void printAllWindows() async {
    final windows = await WinTracker.getAllWindows();
    for (var window in windows) {
      print('Window ID: ${window.id}, Title: ${window.title}');
    }
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('WinTracker Example'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: [
              ElevatedButton(
                onPressed: printCurrentWindowInfo,
                child: Text('Print Current Window Info'),
              ),
              ElevatedButton(
                onPressed: closeCurrentWindow,
                child: Text('Close Current Window'),
              ),
              ElevatedButton(
                onPressed: minimizeCurrentWindow,
                child: Text('Minimize Current Window'),
              ),
              ElevatedButton(
                onPressed: printAllWindows,
                child: Text('Print All Windows'),
              ),
            ],
          ),
        ),
      ),
    );
  }
}
