packList static method

PackedNode packList(List<CircleNode> children, { required double radius, String label = 'Root', double minRadiusRatio = 0.1, })

Packs a list of children into a circle with the given radius, creating a virtual root with the given label.

This is the core utility that enables the "Widget as Root" architecture. It allows users to provide a flat list of top-level categories without needing to wrap them in an explicit "Root" CircleNode in their data model. The packer creates a temporary virtual parent to calculate the initial layout within the available viewport.

Implementation

static PackedNode packList(
  List<CircleNode> children, {
  required double radius,
  String label = 'Root',
  double minRadiusRatio = 0.1,
}) {
  final virtualRoot = CircleNode(label: label, children: children);
  return _packNode(virtualRoot, 0.0, 0.0, radius, minRadiusRatio);
}
