connectionPathCache property

ConnectionPathCache get connectionPathCache

Gets the connection path cache (data layer).

Use this for geometry queries (hit testing, bounds intersection). Throws StateError if accessed before initialization.

Implementation

ConnectionPathCache get connectionPathCache {
  if (_connectionPathCache == null) {
    throw StateError(
      'ConnectionPathCache not initialized. '
      'Ensure the controller is used with a NodeFlowEditor widget.',
    );
  }
  return _connectionPathCache!;
}
