Open channel status handler

Listen for status changes​

Register an OpenChannelHandler to receive open channel status and participant change events.

Dart
NCEngine.addOpenChannelHandler('open-handler', OpenChannelHandler(
  onStatusChanged: (event) {
    print('Open channel ${event.channelId} status: ${event.status}');
  },
  onParticipantChanged: (event) {
    print(
      'Member change in ${event.channelId}: ${event.actions}, count: ${event.participantCount}',
    );
  },
  onParticipantMuted: (event) {
    print('Member muted: ${event.info?.userIdList}');
  },
  onParticipantBanned: (event) {
    print('Member banned: ${event.info?.userIdList}');
  },
  onNotifyMultiLoginSync: (event) {
    print('Multi-device sync: $event');
  },
));

Remove the handler when it is no longer needed:

Dart
NCEngine.removeOpenChannelHandler('open-handler');

Listen for participant changes​

Enable the service​

Enable Enable auto messaging for participant events in the Nexconn console under Chat > Chat settings > Open Channels. Once enabled, the system sends notifications to other participants when a user joins or leaves.

Use the onParticipantChanged callback in OpenChannelHandler (see above).
