My android devices showing notifications in below format.

below is the payload i am using for sending notification.

 var payload = {   "notification":{
          "title":"New Price Alert! "+ clientDataAfter.productname,
"subtitle":"Get before its gone",
          "body":"Old Price "+clientDataAfter.oldprice+" || New Price "+ clientDataAfter.newprice,
          "click_action":"FLUTTER_NOTIFICATION_CLICK",
        },
        "data" : {
          "id":ID,
          "name": Name,
          "newprice":newprice
