如何使用flutter插件顯示多個通知：flutter_local_notifications

Question

這是我的代碼如下：

const AndroidNotificationChannel notificationChannel = AndroidNotificationChannel(
  'high_importance_channel',
  'high importance Notificaion',
  'this channel is used for import notification',
  importance: Importance.high,
  playSound: true,
);

FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin = FlutterLocalNotificationsPlugin();


Future<void> firebaseBackgroundMessageHandler(RemoteMessage message) async {
  await firebaseMessageHandler(message);
}

Future<void> firebaseForegroundMessageHandler(RemoteMessage message) async {
  await firebaseMessageHandler(message);
}

Future<void> firebaseMessageHandler(RemoteMessage message) async {
  await Firebase.initializeApp();

  try {
    flutterLocalNotificationsPlugin.show(
          message.notification.hashCode,
          message.data["title"].toString(),
          message.data["body"].toString(),
          NotificationDetails(
            android: AndroidNotificationDetails(notificationChannel.id, notificationChannel.name, notificationChannel.description),
          ));
  } catch (_err) {}

}


Future<void> main() async {

  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();

  FirebaseMessaging.onBackgroundMessage(firebaseBackgroundMessageHandler);
  FirebaseMessaging.onMessage.listen(firebaseForegroundMessageHandler);
  //FirebaseMessaging.onMessageOpenedApp.listen(firebaseMessageHandler);

  final AndroidInitializationSettings initializationSettingsAndroid = AndroidInitializationSettings('e_app');

  final InitializationSettings initializationSettings = InitializationSettings(android: initializationSettingsAndroid);

  await flutterLocalNotificationsPlugin.initialize(initializationSettings);

  await flutterLocalNotificationsPlugin.resolvePlatformSpecificImplementation<AndroidFlutterLocalNotificationsPlugin>()?.createNotificationChannel(notificationChannel);

  await FirebaseMessaging.instance.setForegroundNotificationPresentationOptions(alert: true, badge: true, sound: true);
}

代碼對於單個通知工作正常，但是每當我向 android 發送多個通知時，它只在狀態欄中顯示最后一個通知。

有人可以幫助我了解如何使用 Flutter 本地通知插件在狀態欄中顯示多個通知嗎？

如果您想對通知進行分組，可以在 flutter_local_notifications 中選擇這樣做。 為此，您可以在代碼中添加以下內容

對於 ios ：IOSNotificationDetails 中的 threadIdentifier

安卓：groupChannelId、groupChannelName、groupChannelDescription、

您可以在此處的文檔中找到這些： https : //pub.dev/packages/flutter_local_notifications#displaying-a-notification在“分組通知”下。

基本上相同 threadId 或 groupId 下的通知都將被分組並顯示
