You are using firebase authentication so

  1. Make sure that google-services.json is in assets.
  2. Make sure it doesn’t have a number, like google-services(1).json.
  3. The package name of your app, and the package name you provided to firebase to download “google-services.json” MUST be the same
  4. and finally check if firebase url is missing from json
