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

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

  1. Go to https://console.firebase.google.com/
  2. Select the project
  3. Click on the Project Overview → Project Settings
  4. Select "Cloud Messaging" tab.
  5. 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
