getUndeliveredMembers method

List<Member> getUndeliveredMembers(
  1. BaseMessage message
)

Returns the list of members that haven't received the given message. This excludes the current logged-in User and the Sender of the message. It will always be zero if the passed on message is an AdminMessage, or if this channel is a super group channel.

Implementation

List<Member> getUndeliveredMembers(BaseMessage message) {
  sbLog.i(StackTrace.current, 'messageId: ${message.messageId}');
  if (message is AdminMessage) return [];
  if (isSuper) return [];

  final deliveryStatus =
      chat.channelCache.find<DeliveryStatus>(channelKey: channelUrl);

  if (deliveryStatus == null) return [];

  return members.where((m) {
    if (m.isCurrentUser) return false;
    if (message.sender?.userId == m.userId) return false;
    if (m.memberState != MemberState.joined) return false;
    final deliveredAt = deliveryStatus.updatedDeliveryStatus[m.userId] ?? 0;
    return deliveredAt < message.createdAt;
  }).toList();
