Flutter 向令牌发送 firebase 通知

Flutter send firebase notification to token

所以我有一个聊天应用程序,我想要它,这样我就可以在有人向我发送消息时收到通知。问题是我实现了 firebase 消息传递,如果我从 firebase 发送它,我可以收到通知。我想添加它,例如一旦我按下发送按钮,我就可以直接将通知发送到应用程序中的令牌,例如:

send notification{
   to token : here the receiver token
   title : the title of the notification
   description : the description of the notification  
} 

有没有可能有这样的东西?

只是为了帮助,

如果有人想使用 REST POST API,就在这里,使用配置如下的 Postman

URL:
https://fcm.googleapis.com/fcm/send

Header:

"Content-Type": "application/json",
"Authorization": "key=<Server_key>"

BODY:

{
    "to": "<Device FCM token>",
    "notification": {
      "title": "Check this Mobile (title)",
      "body": "Rich Notification testing (body)",
      "mutable_content": true,
      "sound": "Tri-tone"
      },
      
   "data": {
    "url": "<url of media image>",
    "dl": "<deeplink action on tap of notification>"
      }
}
