Usage

Use enough_mail_icalendar to generate and send MIME email messages for iCalendar requests.

Import

import 'package:enough_icalendar/enough_icalendar.dart';
import 'package:enough_mail/enough_mail.dart';
import 'package:enough_mail_icalendar/enough_mail_icalendar.dart';

Generate a MimeMessage for a VCalendar

With VMessageBuilder.prepareFromCalendar(...) create a MIME message builder for a given VCalendar object.

void buildCalendarInviteMessage(VCalendar invite) {
  final builder = VMessageBuilder.prepareFromCalendar(invite);
  final mimeMessage = builder.buildMimeMessage();
  print(mimeMessage);
  // you can now send the MimeMessage as any other message, e.g. with `MailClient.sendMessage(mimeMessage)`
}

Generate a Reply MimeMessage for a Received VCalendar

Use VMessageBuilder.prepareCalendarReply(...) to create a reply MIME message for a received VCalendar. In the following example the invite is accepted.

void buildAcceptReplyMessage(VCalendar invite) {
  final me = MailAddress('Donna Strickland', '[e-mail]');
  final acceptMessageBuilder = VMessageBuilder.prepareCalendarReply(
    invite,
    ParticipantStatus.accepted,
    me,
  );
  final mimeMessage = acceptMessageBuilder.buildMimeMessage();
  print(mimeMessage);
}

Send a Reply directly for a Received VCalendar

Send a reply directly with the MailClient.sendCalendarReply() instance method. This will generate the mime message, send it and update the originating message's flags, when the message is specified and when the mail service supports arbitrary message flags.

Future sendCalendarReply(
  VCalendar calendar,
  ParticipantStatus participantStatus,
  MimeMessage originatingMessage,
  MailClient mailClient,
) {
  // generate reply email message, send it, set message flags:
  return mailClient.sendCalendarReply(calendar, participantStatus,
      originatingMessage: originatingMessage);
}

Check if a Reply has been Send for a MimeMessage

Use the calendarParticipantStatus getter on a MimeMessage instance to check for participation status flags that have been set earlier.

ParticipantStatus? getParticipantStatus(MimeMessage message) {
  // the ParticipantStatus can be detected from the message flags when
  //the flag was added successfully before
  final participantStatus = message.calendarParticipantStatus;
  if (participantStatus != null) {
    print(
        'detected ${participantStatus.name} through flag ${participantStatus.flag}');
  } else {
    print('no participant status flag detected in ${message.flags}');
  }
  return participantStatus;
}
