Flutter本地通知插件simple_local_notifications的使用

当然，以下是如何在Flutter项目中使用simple_local_notifications插件来实现本地通知的一个详细示例。

1. 添加依赖

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

dependencies:
  flutter:
    sdk: flutter
  simple_local_notifications: ^x.y.z  # 请替换为最新版本号

然后运行flutter pub get来安装依赖。

2. 导入插件

在你的Dart文件中导入插件：

import 'package:simple_local_notifications/simple_local_notifications.dart';
import 'package:flutter_local_notifications/flutter_local_notifications.dart' as flutterLocalNotifications;

3. 初始化插件

在你的main.dart或适当的初始化位置，配置并初始化插件：

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

  // 配置FlutterLocalNotificationsPlugin
  var initializationSettingsAndroid = new flutterLocalNotifications.AndroidInitializationSettings('@mipmap/ic_launcher');
  var initializationSettingsIOS = new flutterLocalNotifications.IOSInitializationSettings(requestAlertPermission: true, requestBadgePermission: true, requestSoundPermission: true);
  var initializationSettings = new flutterLocalNotifications.InitializationSettings(android: initializationSettingsAndroid, iOS: initializationSettingsIOS);
  flutterLocalNotificationsPlugin.initialize(initializationSettings, new flutterLocalNotifications.OnInitializationCompleteCallback {
    @override
    void onInitializationComplete(flutterLocalNotifications.InitializationStatus status) {
      if(!status.isEnabled) {
        print('Local notifications are not enabled on this device.');
        return;
      }
      print('Local notifications are enabled on this device.');

      // 配置SimpleLocalNotificationsPlugin
      simpleLocalNotificationsPlugin.initialize(flutterLocalNotificationsPlugin);
    }
  });

  runApp(MyApp());
}

4. 创建通知

在你的应用逻辑中创建和显示通知：

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

              var androidPlatformChannelSpecifics = new flutterLocalNotifications.AndroidNotificationDetails(
                'your channel id',
                'Your Channel Name',
                'Your Channel Description',
                importance: flutterLocalNotifications.Importance.High,
                priority: flutterLocalNotifications.NotificationPriority.High
              );
              var iOSPlatformChannelSpecifics = new flutterLocalNotifications.IOSNotificationDetails();
              var platformChannelSpecifics = new flutterLocalNotifications.NotificationDetails(
                android: androidPlatformChannelSpecifics,
                iOS: iOSPlatformChannelSpecifics
              );

              await simpleLocalNotificationsPlugin.show(
                100, // id
                'Local Notification Title',
                'This is the body of the notification',
                platformChannelSpecifics
              );
            },
            child: Text('Show Notification'),
          ),
        ),
      ),
    );
  }
}

5. 处理通知点击事件

你可能还需要处理用户点击通知时的逻辑：

void configureSelectNotificationSubject(FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin) {
  flutterLocalNotificationsPlugin.onNotificationOpenedApp.listen((String payload) async {
    // 用户点击通知打开应用时的逻辑
    print('onNotificationOpenedApp: $payload');
  });

  flutterLocalNotificationsPlugin.onNotificationAction.listen((flutterLocalNotifications.NotificationAction action) async {
    // 用户点击通知中的按钮时的逻辑
    print('onNotificationAction: ${action.key}');
  });

  flutterLocalNotificationsPlugin.onSelectNotification.listen((String payload) async {
    // 用户点击通知（在通知栏中）时的逻辑，但不打开应用
    print('onSelectNotification: $payload');
  });
}

在main函数中调用configureSelectNotificationSubject：

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

  // 配置FlutterLocalNotificationsPlugin（同上）
  // ...

  configureSelectNotificationSubject(flutterLocalNotificationsPlugin);

  runApp(MyApp());
}

这个示例展示了如何使用simple_local_notifications插件来发送本地通知，并处理用户与通知的交互。请确保根据实际需求调整代码，如通知ID、标题、内容以及通道设置等。
