Set the Email Date Header to the Current System Date/Time

Demonstrates how to set the Date header field of an email to the computer's current date/time. Note: When an email object is instantiated, the Date header field is automatically added and initialized to the current system date/time. The need to explicitly set the Date header could arise when loading an email from a .eml. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  final email = CkEmail();

  // At this point, a new email object has been instantiated, and it
  // already has a Date header field containing the current date/time.
  print('Date: ${email.emailDateStr}');

  // We can also get the Date header like this:
  print('Date: ${email.getHeaderField('Date')}');

  // Load a .eml into the email object:
  try {
    email.loadEml('myEmlFiles/someEmail.eml');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Show the Date that was in the .eml
  print('Date: ${email.emailDateStr}');

  // Now the Date header contains whatever was in the .eml
  // Let's update it to the current system date/time..

  final dateTime = CkDateTime();

  dateTime.setFromCurrentSystemTime();

  try {
    email.setDt(dateTime);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Now show that the Date is the current system time:
  print('Date: ${email.emailDateStr}');
  print('Date: ${email.getHeaderField('Date')}');
}
