Default FirebaseApp is not initialized in this process [package name].
Make sure to call FirebaseApp.initializeApp(Context) first.

Note: When you are debugging on android, use a device or AVD with Google Play services. Otherwise you will not be able to use Firebase Remote Config.

import 'package:firebase_remote_config/firebase_remote_config.dart';

final RemoteConfig remoteConfig = await RemoteConfig.instance;

You can now use the Firebase remoteConfig to fetch remote configurations in your Dart code, e.g.

final defaults = <String, dynamic>{'welcome': 'default welcome'};
await remoteConfig.setDefaults(defaults);

await remoteConfig.fetch(expiration: const Duration(hours: 5));
await remoteConfig.activateFetched();
print('welcome message: ' + remoteConfig.getString('welcome'));
