searchAllTreesWithTitleDFS<T extends AbsNodeType> function

void searchAllTreesWithTitleDFS<T extends AbsNodeType>(TreeType<T> tree, String text, List<TreeType<T>> result)

Using DFS to return all the trees if each of root's data contains searching text

Implementation

void searchAllTreesWithTitleDFS<T extends AbsNodeType>(
    TreeType<T> tree, String text, List<TreeType<T>> result) {
  if (tree.data.isUnavailable) return;

  final searchText = text.toLowerCase();
  final originTitle = tree.data.title.toLowerCase();
  if (originTitle.contains(searchText) || originTitle.toNoneDiacritics.contains(searchText)) {
    result.add(tree);
  }

  for (var child in tree.children) {
    searchAllTreesWithTitleDFS(child, text, result);
  }
}
