startConnect method

Future<ConnectionTask<SecureSocket>> startConnect (dynamic host, int port, { SecurityContext context, bool onBadCertificate(X509Certificate certificate), List<String> supportedProtocols })

Like connect, but returns a Future that completes with a ConnectionTask that can be cancelled if the SecureSocket is no longer needed.

Implementation 

static Future<ConnectionTask<SecureSocket>> startConnect(host, int port,
    {SecurityContext context,
    bool onBadCertificate(X509Certificate certificate),
    List<String> supportedProtocols}) {
  return RawSecureSocket.startConnect(host, port,
          context: context,
          onBadCertificate: onBadCertificate,
          supportedProtocols: supportedProtocols)
      .then((rawState) {
    Future<SecureSocket> socket =
        rawState.socket.then((rawSocket) => new SecureSocket._(rawSocket));
    return new ConnectionTask<SecureSocket>._(
        socket: socket, onCancel: rawState._onCancel);
  });
}
