# children property Null safety

List<Element> children

## Implementation

    List<Element> get children {
      if (_docChildren == null) {
        _docChildren = new FilteredElementList(this);
      }
      return _docChildren!;
    }

void children= (List<Element> value)

## Implementation

    set children(List<Element> value) {
      // Copy list first since we don't want liveness during iteration.
      var copy = value.toList();
      var children = this.children;
      children.clear();
      children.addAll(copy);
    }
