close method

  1. @override
Future<void> close()

Closes the event and state Streams. This method should be called when a Bloc is no longer needed. Once close is called, events that are added will not be processed. In addition, if close is called while events are still being processed, the Bloc will finish processing the pending events.

Implementation

@override
Future<void> close() {
  // Cancel timers
  _typingDebounceTimer?.cancel();
  _batchEmitTimer?.cancel();
  _pendingEvents.clear();
  _conversationIndexMap.clear();

  // Dispose typing notifiers
  for (final notifier in _typingNotifiers.values) {
    notifier.dispose();
  }
  _typingNotifiers.clear();

  // Remove SDK listeners
  CometChat.removeMessageListener(_messageListenerKey);
  if (usersStatusVisibility) {
    CometChat.removeUserListener(_userListenerKey);
  }
  CometChat.removeGroupListener(_groupListenerKey);
  CometChat.removeCallListener(_callListenerKey);
  CometChat.removeConnectionListener(_connectionListenerKey);

  // Remove CC UI Event listeners
  CometChatMessageEvents.removeMessagesListener(_ccMessageListenerKey);
  CometChatGroupEvents.removeGroupsListener(_ccGroupListenerKey);
  CometChatConversationEvents.removeConversationListListener(
      _ccConversationListenerKey);

  _isLoadingMore = false;
  return super.close();
