analyze static method

List<ConstraintChainLink> analyze(RenderObject target, { int maxDepth = 20, })

Analyze the constraint chain from target up to the root (or up to maxDepth ancestors).

Returns a list of ConstraintChainLinks ordered from the target (depth 0) to the furthest ancestor analyzed.

Implementation

static List<ConstraintChainLink> analyze(
  RenderObject target, {
  int maxDepth = 20,
}) {
  final chain = <ConstraintChainLink>[];
  RenderObject? current = target;
  int depth = 0;

  while (current != null && depth <= maxDepth) {
    Size? size;
    if (current is RenderBox && current.hasSize) {
      size = current.size;
    }

    // ignore: invalid_use_of_protected_member
    final currentConstraints = current.constraints;
    chain.add(ConstraintChainLink(
      widgetType: current.runtimeType.toString(),
      constraints: currentConstraints,
      size: size,
      depth: depth,
    ));

    current = current.parent;
    depth++;
  }

  return chain;
