android - 如何从 OneSignal 推送通知 Flutter 中提取消息标题和正文

Question

伙计们，我正在尝试从 OneSignal 推送通知中获取通知标题和正文我已经尝试从像 HTTP 一样的 JSON 中获取数据，但它没有用

OneSignal.shared
        .setNotificationReceivedHandler((OSNotification notification) {
      // will be called whenever a notification is received

      print('Recived Notification is : $notification');

      notification.convertToJsonString({'title': title, 'alert': body});

      print('Title is : $title');
      print('Description is : $body');
    });


onesignal( 9471): Created json raw payload: {vis=1, google.original_priority=normal, google.sent_time=1566080374593, pri=5, grp_msg=, google.delivered_priority=normal, custom={"i":"cb91f929-3008-4364-a687-1675448c2d0a"}, oth_chnl=, title=Welcom test Notification, google.message_id=0:1566080374598190%ab53bc02f9fd7ecd, alert=this is description of welcome text content notification, google.ttl=259200, from=613584415888, notificationId=173367476}
I/flutter ( 9471): Recived Notification is : Instance of 'OSNotification'
I/flutter ( 9471): Title is : null
I/flutter ( 9471): Description is : null

我已经解决了我的问题，它只是像这样获取通知的有效负载

OneSignal.shared
      .setNotificationReceivedHandler((OSNotification notification) {
    // will be called whenever a notification is received

    print('Recived Notification is : $notification');

    title = notification.payload.title;
    body = notification.payload.body;
  });
