Check for the following, if you have missed some steps:

Create a firebase project in the firebase console.

Make sure the bundleID of the app matches with the bundle ID of the project created in Console.

Android: Make sure you have copied the google-services.json file to the Android>app directory (copy item if needed)

iOS: Make sure you have copied the GoogleServices-Info.plist file to iOS>Runner directory.

try flutter clean and restart the app

You need to intialize FlutterFire first by calling await Firebase.initializeApp(); before using any Firebase services.

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  await Firestore.initializeApp();
  runApp(BookApp()
}
