Import connectivity_plus package and use below code.

import 'package:connectivity_plus/connectivity_plus.dart';

var connectivityResult = await (Connectivity().checkConnectivity());
if (connectivityResult != ConnectivityResult.mobile && connectivityResult != ConnectivityResult.wifi) {
  //Internet is not connected
} else {
  // Internet is connected
}

With this package https://pub.dev/packages/connectivity_plus

var connectivityResult = await (Connectivity().checkConnectivity());
    if (connectivityResult == ConnectivityResult.none) {
        showDialog();
    }

or you setup a listener and watch yor connectivitiy changes

 subscription = Connectivity().onConnectivityChanged.listen((ConnectivityResult result) {
    // Got a new connectivity status!
  })
