subtreeHasBadge<T> static method

bool subtreeHasBadge<T>(NavNode<T> node)

True when node or anything beneath it carries a badge — used to mark a collapsed module/rail icon with a dot.

Implementation

static bool subtreeHasBadge<T>(NavNode<T> node) {
  if (node.badge != null) return true;
  for (final c in node.children) {
    if (subtreeHasBadge(c)) return true;
  }
  return false;
}
