          builder: (context , child){
            return StreamBuilder<InternetConnectionStatus>(
              stream:  InternetConnectionChecker().onStatusChange,
              builder: (context , snapshot){
                final connectivityResult = snapshot.data;
                print("result"+connectivityResult.toString());
                if(connectivityResult.toString()=="InternetConnectionStatus.disconnected") {
                  return NoInternet();
                }

  1. You should use the below written code

    The data_connection_checker package is used in it

         Future<bool> isInternet() async {
    var connectivityResult = await (Connectivity().checkConnectivity());
    if (connectivityResult == ConnectivityResult.mobile) {
      
      if (await DataConnectionChecker().hasConnection) {
        return true;
      } 
else {
        return false;
      }
    } 
else if (connectivityResult == ConnectivityResult.wifi) {
      
      if (await DataConnectionChecker().hasConnection) {
        return true;
      } 
else {
        return false;
      }
    } 
else {
      return false;
    }
  }

    You can return the statement as you want, like alert message or navigation to ‘No Network’ Screen
