nodesAt method

List<Node<T>> nodesAt(
  1. Offset point, {
  2. double radius = 0,
})

Gets all visible nodes at a point.

Implementation

List<Node<T>> nodesAt(Offset point, {double radius = 0}) {
  return _grid
      .queryPoint(point, radius: radius)
      .whereType<NodeSpatialItem>()
      .map((item) => _nodes[item.nodeId])
      .whereType<Node<T>>()
      .where((node) => node.isVisible)
      .toList();
}
