Remove firebase from flutter project

To remove Firebase from a Flutter project, you need to perform the following steps:

1. Remove Firebase dependencies from pubspec.yaml file:


dependencies:
  flutter:
    sdk: flutter
  firebase_core: ^1.7.0
  firebase_auth: ^3.3.0
  cloud_firestore: ^3.1.0
  firebase_messaging: ^11.2.2
  firebase_analytics: ^10.2.0
  firebase_crashlytics: ^2.5.6
  firebase_performance: ^3.3.0


Remove the above Firebase dependencies from the pubspec.yaml file.

2. Run the command:


flutter pub get


3. Remove the Firebase configuration files:

Inside the android/app directory, delete the google-services.json file.

Inside the ios/Runner directory, delete the GoogleService-Info.plist file.

4. Remove Firebase initialization code:

Open the lib/main.dart file and remove the Firebase initialization code, which typically looks like this:


import 'package:firebase_core/firebase_core.dart';

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


Remove the above code block from the main() function.

5. Clean the project:

Run the command:


flutter clean


6. Build and run the project:

Finally, build and run your project using the command:


flutter run


After completing these steps, Firebase should be removed from your Flutter project.
