internalUpdateNodeShapeBuilder method

void internalUpdateNodeShapeBuilder(NodeShape? builder(Node<T> node)?)

Updates the node shape builder on an already-initialized controller.

@internal - This method is for internal use by NodeFlowEditor only. Do not call directly from application code.

This also updates the spatial index callback to use the new builder.

Implementation

void internalUpdateNodeShapeBuilder(
  NodeShape? Function(Node<T> node)? builder,
) {
  _nodeShapeBuilder = builder;
  _spatialIndex.nodeShapeBuilder = builder;

  // Update connection painter if it exists
  _connectionPainter?.updateNodeShape(
    builder != null ? (node) => builder(node as Node<T>) : null,
  );
}
