Connect a TCP or TLS Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.Connect, which establishes a TCP connection to a host and port. Setting the TLS argument to _TRUE_ performs a TLS handshake after the TCP connection succeeds.

import 'package:chilkat/chilkat.dart';

void main() {
  final socket = CkSocket();

  // Connect to the server using TLS.  The 3rd argument enables the TLS handshake after the TCP
  // connection succeeds; the 4th is the maximum time to wait, in milliseconds.
  final bTls = true;
  final maxWaitMs = 5000;
  try {
    socket.connect('example.com', 5000, bTls, maxWaitMs);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // StringCharset controls the character encoding used when sending and receiving text.
  socket.stringCharset = 'utf-8';

  // The socket is now connected and ready to send and receive data using whatever protocol the
  // application implements.
  print('Connected: ${socket.isConnected}');

  // Close the connection when finished.  The argument is the maximum time to wait for a clean
  // shutdown, in milliseconds.
  try {
    socket.close(1000);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }
