我在两个平台上都遇到了FCM插件（https://ionicframework.com/docs/native/fcm）的问题，该问题是我无法处理应用程序关闭/杀死时的通知，onNotification（）方法未被激发（它在后台和前台工作正常）

this.fcm.onNotification().subscribe((payload) => {
          if (payload.wasTapped) {
            console.log('Notification received in background');
          } else {
            console.log('Notification received in foreground');
          }
          console.log('Notification payload: ',payload);
  });

通知主体在后台和前台都工作正常（两个平台）：

{
 "to" : <device-key>,
"collapse_key" : "app-key",
 "notification" : {
     "body" : "body",
     "title": "title"
 },
 "data" : {"parameter":"1"},
 "android": {
    "notification": {
      "click_action": "FCM_PLUGIN_ACTIVITY"
    }
  }
}

I believe your subscription is inside the constructor or inside the onInit function.
It does not matter if the app is in the foreground or the background, since the app is working, the subscription gets invoked.
But when the app is killed, how does the subscription gets invoked?. When you receive the notification, you tap on it. then only the app starts. after the app is started only, the subscription is active.
What you have to do is, invoke the fcm.getInitialPushPayload() when the app starts.
Place following inside your constructor.

this.platform.ready().then(() => {

    this.fcm.getInitialPushPayload().then((payload) => {
  
      if(payload.wasTapped) {
        console.log("Received FCM when app is closed -> ", JSON.stringify(payload));
        // call your function to handle the data
        this._handlePushNotificationData(payload);
      }                                 
      
    });

}

Now, when the app is closed, when you tap on the notification you received, the app will start and the above function will be called. Then your data will be available in the callback.
