NodeInfo class

Represents information about a specific SVG node within an SVG.

The NodeInfo class holds the identifier of a node along with its element position and cursor position, as described by NodeCoordinate.

This class is used by the JujubaCommander to trigger commands in a specific SVG region or node.

Example:

final node = NodeInfo(
  id: 'circle_1',
  elementPosition: NodeCoordinate(x: 10, y: 20),
);

print(node.id); // circle_1
print(node.elementPosition.x); // 10
