import 'package:chilkat/chilkat.dart';

void main() {
  final upload = CkUpload();

  // Specify the page (ASP, ASP.NET, Perl, Python, Ruby, CGI, etc)
  // that will receive and process the HTTPS Upload.
  upload.hostname = 'www.mywebserver.com';
  upload.path = '/receiveUpload.aspx';

  // Make sure to indicate that TLS is to be used, and the port should be
  // 443 rather than 80.
  upload.ssl = true;
  upload.port = 443;

  // Add one or more files to be uploaded.
  upload.addFileReference('file1', 'dude.gif');
  upload.addFileReference('file2', 'swordfish.xml');
  upload.addFileReference('file3', 'sample.doc');

  // Do the upload.  The method returns when the upload
  // is completed.
  // This component also includes asynchronous upload capability,
  // which is demonstrated in another example.
