Example

final port = Port(
  id: 'input-1',

  widgetBuilder: (context, node, port) {
    final myNode = node as Node<MyData>;
    return Container(
      width: 12,
      height: 12,
      decoration: BoxDecoration(
        color: myNode.data?.isActive == true ? Colors.green : Colors.blue,
        shape: BoxShape.circle,
      ),
    );
  },
);
