如何在flutter中找到任何元素中包含另一个列表的列表？

List<dynamic> findElementsContainingList(List<dynamic> inputList, List<dynamic> targetList) {
  List<dynamic> results = [];

  void searchList(List<dynamic> list) {
    for (var item in list) {
      if (item is List<dynamic>) {
        searchList(item);
      } else if (item.containsAll(targetList)) {
        results.add(item);
      }
    }
  }

  searchList(inputList);
  return results;
}

void main() {
  List<dynamic> inputList = [
    [1, 2, 3],
    [4, [5, 6, [7, 8]], 9],
    [10, [11, [12, 13]], 14],
  ];
  List<dynamic> targetList = [5, 6];

  List<dynamic> foundElements = findElementsContainingList(inputList, targetList);
  print(foundElements);  // 输出：[[5, 6, [7, 8]]]
}
