5. Easy to use. Very easy to use!

Usage #

Initialization:

import 'package:vkdart/vkdart.dart';

void main() async {
  final TOKEN = ''; // Group Token
  final vkdart = VkDart(TOKEN, groupId: 123);

  vkdart.start();
}

Listening to events:

// message_new, message_edit, message_reply
vkdart.onMessage().listen((event) => print('A message has arrived!\n\n'
    'From ID: ${event.senderId}\n'
    'From Type: ${event.senderType.name}\n'
    'Dialog ID: ${event.peerId}\n'
    'Dialog Type: ${event.peerType.name}\n'
    'Outbox: ${event.isOutbox}'));

// message_event
vkdart.onMessageEvent().listen((event) => print(
    'The user clicked on the Callback button!\n'
    'Dialog ID: ${event.peerId}\n'
    'UserID: ${event.userId}'
    '${event.eventPayload != null ? '\nPayload: ${event.eventPayload}' : ''}'
    '\nEventID: ${event.eventId}'));

Listening on unsupported events:

vkdart
    .onUnsupportedEvent()
    .listen((event) => print('An unsupported event has arrived!\n'
        'It is necessary to inform the chat https://t.me/vk_dart\n\n'
        'Type of event ${event.eventType}\n'
        'Event Object: ${event.object}'));

Modifying Stream:

vkdart
    .onComment()
    .where((event) => event.isPhotoComment && event.isNew)
    .listen((event) => print('Commented on the photo!\n\n'
        'Owner ID: ${event.ownerId}\n'
        'Photo ID: ${event.objectId}'
        '${event.attachments.isNotEmpty ? '\nAttachments: ${event.attachments}' : ''}'));
