    start your app to run again (don’t hot restart / hot reload)

    STOP THE APP AND RE-RUN

    you’re using the discounted package for checking connectivity and that package is not supported on the Linux platform you can check here, You can use connectivity_plus, you can use a similar code to check the internet connectivity, just need to change the import file line.
    As shown below,

    import package

    import 'package:connectivity_plus/connectivity_plus.dart';

    connectivity checking

    Future<bool> checkInternetConnection() async {
    var connectivityResult = await Connectivity().checkConnectivity();
    return connectivityResult != ConnectivityResult.none;
  }

    NOTE: This doesn’t check the active internet connection with the device you have to write separate logic for that you can you internet_connection_checker_plus package for the same purpose.
