getPortWorldPosition method

Offset? getPortWorldPosition(String nodeId, String portId)

Gets the world position of a port.

Returns the center position of the port in graph coordinates. Returns null if the node or port doesn't exist.

Example:

final position = controller.getPortWorldPosition('node1', 'output1');
if (position != null) {
  print('Port at: $position');
}

Implementation

Offset? getPortWorldPosition(String nodeId, String portId) {
  final node = _nodes[nodeId];
  if (node == null) return null;

  final port = getPort(nodeId, portId);
  if (port == null) return null;

  // Use the node's getPortCenter method which handles coordinate conversion
  // We need the theme to get the port size for accurate calculations
  if (_theme == null) return null;
  final portSize = _theme!.portTheme.resolveSize(port);

  try {
    return node.getPortCenter(
      portId,
      portSize: portSize,
      shape: _nodeShapeBuilder?.call(node),
    );
  } catch (_) {
    return null;
  }
}
