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) {
  final newCases = <(LatexNode, LatexNode)>[];
  int idx = 0;
  for (int i = 0; i < cases.length; i++) {
    newCases.add((newChildren[idx++], newChildren[idx++]));
  }
  return CasesNode(
    newCases,
    style: style,
    rowGaps: rowGaps,
    sourceRange: sourceRange,
  );
}
