Question

我试图在Flutter制作的应用中处理FCM通知，以使用flutter_local_notifications插件显示通知以自定义通知，但由于某些原因，通知未随插件一起显示，但默认情况下为通知。为了验证我显示的通知是使用flutter_local_notifications插件创建的通知，我在通知标题之前添加了“ X”。但是通知显示为好像您没有通过flutter_local_notifications处理通知一样，标题的开头没有“ X”。

这是我的代码：

我在这里配置FCM

_firebaseMessaging.configure(
      onMessage: (Map<String, dynamic> message) async {
        print('on message $message');
      },
      onBackgroundMessage: myBackgroundMessageHandler,
      onResume: (Map<String, dynamic> message) async {
        print('on resume $message');
      },
      onLaunch: (Map<String, dynamic> message) async {
        print('on launch $message');
      },
    );

我的处理程序：

Future<dynamic> myBackgroundMessageHandler(Map<String, dynamic> message) {

  if (message.containsKey('data')) {
    // Handle data message
    final dynamic data = message['data'];
  }

  if (message.containsKey('notification')) {
    final dynamic notification = message['notification'];
    _showNotification(notification['title'], notification['body']);
  }

}

以及“ showNotification”方法：

_showNotification(String descripcion , String titulo) async {
    
  FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin;
  flutterLocalNotificationsPlugin = new FlutterLocalNotificationsPlugin();
  var android = new AndroidInitializationSettings('@mipmap/ic_launcher');
  var iOS = new IOSInitializationSettings();
  var initSetttings = new InitializationSettings(android, iOS);
  flutterLocalNotificationsPlugin.initialize(initSetttings,
      onSelectNotification: onSelectNotification);

  String groupKey = 'com.witway.proyectox';
  var androidPlatformChannelSpecifics = new AndroidNotificationDetails(
    'ProyectoX',
    'ProyectoX',
    'ProyectoX',
    importance: Importance.Max,
    priority: Priority.High,
    groupKey: groupKey,
    //   setAsGroupSummary: true
  );

  var iOSPlatformChannelSpecifics = new IOSNotificationDetails();
  NotificationDetails platformChannelSpecifics = new NotificationDetails(
      androidPlatformChannelSpecifics, iOSPlatformChannelSpecifics);
  flutterLocalNotificationsPlugin.show(0,"X"+ titulo, descripcion, platformChannelSpecifics);

}
