setSelectedKeys method

void setSelectedKeys(List<K> keys)

Sets the selected keys programmatically. This will try to resolve to items if data is loaded.

Implementation

void setSelectedKeys(List<K> keys) {
  if (_keyExtractor == null) {
    throw StateError('Cannot set selected keys without keyExtractor');
  }

  _selectedItems.clear();
  _selectedKeys.clear();
  _pendingKeys.clear();

  final keysToAdd = _maxSelections != null
      ? keys.take(_maxSelections!)
      : keys;

  for (final key in keysToAdd) {
    _selectedKeys.add(key);

    // Try to find the item
    final state = _cubit.state;
    if (state is SmartPaginationLoaded<T>) {
      bool found = false;
      for (final item in state.items) {
        if (_keyExtractor!(item) == key) {
          _selectedItems.add(item);
          found = true;
          break;
        }
      }
      if (!found) {
        _pendingKeys.add(key);
      }
    } else {
      _pendingKeys.add(key);
    }
  }

  // Start listening for data if there are pending keys
  if (_pendingKeys.isNotEmpty) {
    _cubitSubscription ??= _cubit.stream.listen(_onCubitStateChanged);
  }

  _notifySelectionChanged();
  notifyListeners();
