Flutter - 如何使用 FCM onResume 和 onLaunch 方法？

Question

我的问题似乎类似于这个firebase_messaging onResume 和 onLaunch 不起作用但是我认为该解决方案对我不起作用，因为我已经在尝试访问数据属性中的字段。

当应用程序运行并且该部分工作正常时，我目前正在向用户显示推送通知。但是，我还想在应用程序处于后台时显示通知，并且当用户单击它时，应该会收到一条警报消息。

在 onResume 方法中，如果我这样做，它会起作用，当我打开通知时，我会看到控制台上打印的消息以及警报消息

onResume: (Map<String, dynamic> message) async {
    print("onResume: $message");
    Alert(context: context, title: 'Hi User!').show();
}

但是，如果我尝试访问标题中的数据属性，我会看到控制台上打印的消息，但我现在看不到任何警报

onResume: (Map<String, dynamic> message) async {
    print("onResume: $message");
    Alert(context: context, title: message['data']['user']['name']).show();
}

当应用程序在onMessage属性中运行时，同一段代码有效，但是对于两者onLaunch，onResume我都看到了上述行为。以下是来自控制台的日志

click_action: 'FLUTTER_NOTIFICATION_CLICK'您必须在通知负载中添加新的键值 。喜欢关注

{
    notification: {
        title: 'Title',
        body: 'Body',
        click_action: 'FLUTTER_NOTIFICATION_CLICK'
    }
}

还在活动标记内的清单文件中添加以下代码

  <intent-filter>
           <action android:name="FLUTTER_NOTIFICATION_CLICK" />
           <category android:name="android.intent.category.DEFAULT" />
  </intent-filter>
