withChildren method

@override LatexNode withChildren(List<LatexNode> newChildren)

Rebuilds itself with a new list of child nodes. The order and number of child nodes must match the return value of children. Leaf nodes return themselves.

Implementation

@override
LatexNode withChildren(List<LatexNode> newChildren) {
  int idx = 0;
  final newBase = newChildren[idx++];
  final newAbove = above != null ? newChildren[idx++] : null;
  final newBelow = below != null ? newChildren[idx] : null;
  return StackNode(
    newBase,
    above: newAbove,
    below: newBelow,
    sourceRange: sourceRange,
  );
}
