Node class

The Node class represents a node in a graphical system with input and output ports, allowing for serialization and deserialization to JSON.

Constructors

Node({required Offset position, required NodeData data, required int id, Size size = const Size(150, 80), List<Port>? inputs, List<Port>? outputs})
Node.fromJson(Map<String, dynamic> json)
The function Node.fromJson parses a JSON map to create a Node object with specified properties.
