FTP Upload / Download to StringBuilder

Demonstrate how to upload from a Chilkat StringBuilder object, and download into a StringBuilder object. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // This example assumes Chilkat Ftp2 to have been previously unlocked.
  // See Unlock Ftp2 for sample code.

  final ftp = CkFtp2();

  ftp.hostname = 'www.my-ftp-server.com';
  ftp.username = 'mFtpLogin';
  ftp.password = 'myFtpPassword';

  // Connect to the FTP server.
  try {
    ftp.connectOnly();
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Authenticate with the FTP server.
  try {
    ftp.loginAfterConnectOnly();
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final sbA = CkStringBuilder();
  sbA.loadFile('qa_data/hamlet.xml', 'utf-8');

  // Upload the contents of sbA to the FTP server.
  final bIncludeBOM = false;
  final remoteFilename = 'hamletFromSb.xml';
  try {
    ftp.putFileSb(sbA, 'utf-8', bIncludeBOM, remoteFilename);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Download...
  final sbB = CkStringBuilder();
  try {
    ftp.getFileSb(remoteFilename, 'utf-8', sbB);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Verify that sbA and sbB have the exact same contents.
  print('size of sbA: ${sbA.length}');
  final bCaseSensitive = true;
  if (sbA.contentsEqualSb(sbB, bCaseSensitive)) {
    print('Contents are equal. Success.');
  } else {
    print('Contents are NOT equal.  Failed.');
  }

  ftp.disconnect();
