To achieve your requirement you can use cloud function to send messages to all devices and the steps to achieve this.

  1. take device access token for all user and save it in your database because without access token you can't send the message to devices never forget to update this toke whenever it changed.
  2. cloud message will trigger always whenever any event occurs in a targeted part of the database.
  3. For cloud message link of tutorials are here

Fcm Tutorial, cloud function Tutorial and this tutorial is very helpful for me.

First thing to do is registering your users to one topic.

FirebaseMessaging.getInstance().subscribeToTopic("MySampleApp");

Then send a post request to fcm api https://fcm.googleapis.com/fcm/send

//HEADERS
Content-Type:application/json
Authorization:key=AIzaSyZ-1u...0GB,./,Udno5aA

//BODY
{
  "to": "/topics/MySampleApp",
  "data": {
      "message": "Hello Everyone!",
  }
}

Then handle the notification in your FirebaseMessagingService. Hope this helps
