Client code:

class App {
  void addShape(double x, double y) {
    final newShape = activeToolFactory.createShape(x, y, activeColor);
    shapes.add(newShape);
  }
}


class PropertyPanel extends StatelessWidget {
  final PropertyWidgetFactories factories;

  @override
  Widget build(BuildContext context) {
    return Row(
        children: propertyWidgetFactories
            .createListWidgetsFrom(activeToolFactory.properties)
            .toList(),
      );
  }
