Recently I changed the “google-services.json” file in my app. The previous developer use different “google-services.json” file, so I changed it for getting firebase analytics. I don’t have the access the previous Firebase project, so I cannot use firebase analytics. After changing the “google-services.json” file, I am not getting push notification in my app. Do I have to change anything from backend? Thanks in advance

No error message, but onMessageReceived isn't getting called. I talked with backend developer, they are saying they are identifying my device. But they didn't update server key. – Mdohammad Sajib Al Seraj Dec 21 '20 at 18:47

Your Backend is still sending the push messages to the previous FireBase project. So when you change the FireBase project and have a new google-services.json configuration you need to update the ServerKey on your backend as well.
How to get the Server Key on Firebase
- Go to https://console.firebase.google.com/
- Select the project
- Click on the Project Overview → Project Settings
- Select "Cloud Messaging" tab.
- Under "Project credentials" you should be able to see the Server key or generate a new one.

Just changing “google-service.json” file won't work
After changing the “google-service.json”, run flutter clean will fix the issue
