void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.

    return MaterialApp(
      title: 'Flutter Demo',

  int _counter = 0;

  @override
  void initState() {
    super.initState();
  }

  void _incrementCounter() async {
    // The network connection verification occurs every time this function is called.
    // It must occur inside an 'async' function, because this verification depends on the 'await' of the result
    // of the 'ping' test in 'example.com' site.

    // VERIFY THE NETWORK CONNECTION:
    if (await ConnectionVerify.connectionStatus()){
      print("I have network connection!");
      // Every time the ConnectionVerify.connectionStatus() returns 'true', there is network connection available.
      // Do your online stuff here
    } else {
      print("I don't have network connection!");
      // So, when the verification returns false, you are Offline, so offline treatments must be done here.
      // Do your offline stuff here
    }
    setState(() {
      _counter++;
    });
  }

  // The default 'counter app' build view
