IMAP LastResponse and LastResponseCode

Demonstrates the IMAP LastResponse and LastResponseCode properties. Dart

import 'package:chilkat/chilkat.dart';

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

  final imap = CkImap();

  // Use TLS
  imap.ssl = true;
  imap.port = 993;
  try {
    imap.connect('imap.gmail.com');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Authenticate, but with an intentionally incorrect password
  // so we can see the contents of the LastErrorText, and also
  // the LastResponse and LastResponseCode properties.
  try {
    imap.login('my_login', 'my_intentionally incorrect_password');
    print('Successfull login, but this example is meant to demonstrate an error, such as a failed login.');
    return;
  } on ChilkatException {
    // imap.login() failed; continue anyway.
  }

  // Let's look at the LastErrorText, and also the LastResponse and LastResponseCode.
  print('LastResponseCode = ${imap.lastResponseCode}');
  print('LastReponse = ${imap.lastResponse}');
  print('LastErrorText = ${imap.lastErrorText}');

  // Sample output:

  // LastResponseCode = AUTHENTICATIONFAILED
  // LastReponse = aaab NO [AUTHENTICATIONFAILED] Invalid credentials (Failure)
  // LastErrorText = ChilkatLog:
