Implementation

List toList() {
  final comments = [];
  final queue = Queue.from(_comments);
  while (queue.isNotEmpty) {
    final comment = queue.removeFirst();
    comments.add(comment);
    if ((comment is! MoreComments) && (comment.replies != null)) {
      queue.addAll(comment.replies._comments);
    }
  }
  return comments;
}
