Flutter本地通知插件flutter_local_notifications_windows的使用

当然，下面是一个关于如何在Flutter项目中使用flutter_local_notifications_windows插件来实现本地通知的示例代码。这个插件允许你在Windows平台上发送本地通知。

1. 添加依赖

首先，你需要在pubspec.yaml文件中添加flutter_local_notifications和flutter_local_notifications_windows依赖：

dependencies:
  flutter:
    sdk: flutter
  flutter_local_notifications: ^9.0.0  # 请确保使用最新版本

dev_dependencies:
  flutter_test:
    sdk: flutter

flutter:
  plugin:
    platforms:
      windows:
        pluginClass: FlutterLocalNotificationsPlugin

dependencies_override:
  flutter_local_notifications_windows:
    path: ../path_to_your_fork_or_local_copy_of_flutter_local_notifications_windows  # 如果你从本地路径引入，可以添加这一行，否则直接使用上面的版本控制

注意：dependencies_override部分通常用于从本地路径引入插件，如果你直接从pub.dev安装，则不需要这一部分。

2. 配置Windows插件

在windows/runner/CMakeLists.txt中，确保你有以下配置来链接必要的库（通常这一步在插件安装时自动完成）：

# Flutter Local Notifications Windows
add_subdirectory(${CMAKE_SOURCE_DIR}/../flutter_local_notifications_windows flutter_local_notifications_windows)
target_link_libraries(runner PRIVATE flutter_local_notifications_windows)

3. 初始化通知插件

在你的Flutter应用的main.dart文件中，初始化通知插件并配置它：

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

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  final FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin = FlutterLocalNotificationsPlugin();

  const InitializationSettings initializationSettings = InitializationSettings(
    windows: const WindowsInitializationSettings()
  );

  flutterLocalNotificationsPlugin.initialize(initializationSettings, onInitializationComplete: (status) {
    if (!status['didInitialize']) {
      // Initialization failed
    }
  });

  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Flutter Local Notifications Example'),
        ),
        body: Center(
          child: ElevatedButton(
            onPressed: () async {
              final FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin = FlutterLocalNotificationsPlugin();

              var androidChannel = const AndroidNotificationChannel(
                'high_importance_channel', // id
                'High Importance Notifications', // title
                'This channel is used for important notifications.', // description
                importance: Importance.high,
              );

              var iosChannel = const IOSNotificationChannel(
                'high_importance_channel', // id
                'High Importance Notifications', // title
                'This channel is used for important notifications.', // description
              );

              if (await flutterLocalNotificationsPlugin.resolvePlatformSpecificImplementation<AndroidFlutterLocalNotificationsPlugin>()?.createNotificationChannel(androidChannel) == null) {
                // Android channel creation failed
              }

              // iOS specific: apple badge count, sound settings, etc.
              var iosSettings = IOSNotificationSettings(
                sound: true,
                alert: true,
                badge: true
              );

              // Create a notification and show it
              var notification = Notification(
                title: 'Hello',
                body: 'World',
                channelKey: 'high_importance_channel',
              );

              await flutterLocalNotificationsPlugin.show(
                notification.hashCode,
                notification.title,
                notification.body,
                NotificationDetails(
                  android: AndroidNotificationDetails(
                    channel.id,
                    channel.name,
                    channel.description,
                    icon: '@mipmap/ic_launcher',
                  ),
                  iOS: IOSNotificationDetails(
                    presentAlert: true,
                    presentSound: true,
                    presentBadge: true,
                  ),
                ),
              );
            },
            child: Text('Show Notification'),
          ),
        ),
      ),
    );
  }
}

4. 运行应用

确保你的Flutter环境已经设置好，并且Windows开发工具链已经配置完成。然后，你可以通过以下命令运行你的应用：

flutter run -d windows

这个示例代码展示了如何在Flutter应用中初始化并使用flutter_local_notifications_windows插件来发送本地通知。你可以根据需求进一步定制通知的内容和行为。
