android上的颤振应用程序在单击通知时不会打开应用程序

按照上的说明，我已实施FCM。虽然我已设置了

单击\u操作：颤振\u通知\u单击

，但当我单击通知托盘项目时，它不会打开应用程序。颤振应用程序从云功能接收的数据如下所示。我如何至少在通知单击时打开应用程序

onMessage: {notification: {title: pi, body: text message.}, 
          data: {USER_NAME: pi, click_action: FLUTTER_NOTIFICATION_CLICK, }}

云功能有效载荷

 const payload = {
        notification: {
            title: sender,
            body: content,
            clickAction: 'ChatActivity',
        },
        data: {
            "click_action": 'FLUTTER_NOTIFICATION_CLICK',
            "USER_NAME": sender,
        }
    };

我还创建了通知通道，并且正确配置了AndroidManifest

private void createNotificationChannel() {
        // Create the NotificationChannel, but only on API 26+ because
        // the NotificationChannel class is new and not in the support library
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            CharSequence name = getString(R.string.app_name);
            String description = getString(R.string.notification_channel_description);
            int importance = NotificationManager.IMPORTANCE_HIGH;
            NotificationChannel channel = new NotificationChannel(getString(R.string.default_notification_channel_id), name, importance);
            channel.setDescription(description);
            // Register the channel with the system; you can't change the importance
            // or other notification behaviors after this
            NotificationManager notificationManager = getSystemService(NotificationManager.class);
            notificationManager.createNotificationChannel(channel);
        }
    }

我已经将单击操作放到了通知json中，它对我来说是有效的

notification: {
  title: sender,
  body: content,
  click_action: 'FLUTTER_NOTIFICATION_CLICK'
}

单击操作仅适用于

onResume

和

onLaunch

回调，因此请确保按照pub.dev文档中的说明实施该操作：

 _firebaseMessaging.configure(
       onMessage: (Map<String, dynamic> message) async {
         print("onMessage: $message");
         _showItemDialog(message);
       },
       onBackgroundMessage: myBackgroundMessageHandler,
       onLaunch: (Map<String, dynamic> message) async {
         print("onLaunch: $message");
         _navigateToItemDetail(message);
       },
       onResume: (Map<String, dynamic> message) async {
         print("onResume: $message");
         _navigateToItemDetail(message);
       },
     );

\u firebaseMessaging.configure(
onMessage：（映射消息）异步{
打印（“onMessage:$message”）；
_showItemDialog（消息）；
},
onBackgroundMessage:myBackgroundMessageHandler，
onLaunch：（映射消息）异步{
打印（“onLaunch:$message”）；
_导航项目详细信息（消息）；
},
onResume：（映射消息）异步{
打印（“onResume:$message”）；
_导航项目详细信息（消息）；
},
);

我试过了，但没用。当我在onMessage上打印有效负载时，它不会显示clickAction:“ChatActivity”或click_action:“Flatter_NOTIFICATION_click”。它只显示了主体和内容。
