addByKey method

void addByKey(K key)

Adds an item by its key. If the item is already loaded, it will be added immediately. Otherwise, the key will be stored as pending.

Implementation

void addByKey(K key) {
  if (_keyExtractor == null) {
    throw StateError('Cannot add by key without keyExtractor');
  }

  if (isMaxSelectionsReached) return;
  if (_selectedKeys.contains(key)) return;

  // Try to find the item in current data
  final state = _cubit.state;
  if (state is SmartPaginationLoaded<T>) {
    for (final item in state.items) {
      if (_keyExtractor!(item) == key) {
        addItem(item);
        return;
      }
    }
  }

  // Item not found - add key and mark as pending
  _selectedKeys.add(key);
  _pendingKeys.add(key);

  // Start listening for data if not already
  _cubitSubscription ??= _cubit.stream.listen(_onCubitStateChanged);

  _notifySelectionChanged();
  notifyListeners();
}
