example/example.dart

import 'package:data_connection_checker/data_connection_checker.dart';

main() async {
  // Simple check to see if we have internet
  print("The statement 'this machine is connected to the Internet' is: ");
  print(await DataConnectionChecker().hasConnection);
  // returns a bool

  // We can also get an enum instead of a bool
  print("Current status: ${await DataConnectionChecker().connectionStatus}");
  // prints either DataConnectionStatus.connected
  // or DataConnectionStatus.disconnected

  // This returns the last results from the last call
  // to either hasConnection or connectionStatus
  print("Last results: ${DataConnectionChecker().lastTryResults}");

  // actively listen for status updates
  var listener = DataConnectionChecker().onStatusChange.listen((status) {
    switch (status) {
      case DataConnectionStatus.connected:
        print('Data connection is available.');
        break;
      case DataConnectionStatus.disconnected:
        print('You are disconnected from the internet.');
        break;
    }
  });

  // close listener after 30 seconds, so the program doesn't run forever
  await Future.delayed(Duration(seconds: 30));
  await listener.cancel();
