ConnectionChecker class abstract

Interface for checking network connectivity.

Implement this in your app controller or connectivity service. The repository uses this to determine whether to fetch from API or cache.

Example:

class AppController implements ConnectionChecker {
  final _connectivity = Connectivity();

  @override
  bool get isConnected => _hasConnection;

  bool _hasConnection = true;

  Future<void> init() async {
    _connectivity.onConnectivityChanged.listen((result) {
      _hasConnection = result != ConnectivityResult.none;
    });
  }
}
