  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  final ftp = CkFtp2();

  // Connect and login to the FTP server.
  try {

    print(e.lastErrorText);
    return;

  // The ListPattern property is our directory listing filter.
  // The default value is "*", which includes everything.
  print(ftp.listPattern);

  // To get file and sub-directory information, simply
  // loop from 0 to ftp.GetDirCount() - 1
