我想将对象标记为收藏夹。
我有一个对象<RobotAnimation>的列表，显示在ListView中。该类有两个字段：title和isFavorite。将对象标记为收藏夹可以正常工作，但在存储该状态时会出现问题。当我搜索所有项目时，在将项目选择为收藏夹后，我的收藏夹项目不会被记住。看起来该状态正在被丢弃。
我可以做些什么来解决这个问题？
事情是这样的：

下面是我的代码：

class RobotAnimation {
  String title;
  bool isFavorite;

  RobotAnimation({required this.title, this.isFavorite = false});

  @override
  String toString() {
    return '{Title: $title, isFavortite: $isFavorite}';
  }
}

class Animations extends StatefulWidget {
  const Animations({super.key});

  @override
  State<Animations> createState() => _AnimationsState();
}

class _AnimationsState extends State<Animations> with TickerProviderStateMixin {
  late TabController _tabController;

  List<RobotAnimation> animations = [];
  List<RobotAnimation> favoriteAnimations = [];
  List<String> results = store.state.animations;
  List<String> defaultFavorites = [];

  List<RobotAnimation> getAnimationList(
      List<String> animations, List<String> favorites) {
    List<RobotAnimation> robotAnimations = [];
    for (var animation in animations) {
      bool isFav = false;
      for (var favorite in favorites) {
        if (favorite == animation) {
          isFav = true;
        }
      }
      robotAnimations.add(RobotAnimation(title: animation, isFavorite: isFav));
    }
    return robotAnimations;
  }

  List<RobotAnimation> filterFavorites() {
    List<RobotAnimation> filtered = favoriteAnimations;
    animations.where((element) => element.isFavorite == true).toList();

    return filtered;
  }

  void filterSearchResults(String query) {
    List<RobotAnimation> searchList =
        getAnimationList(results, defaultFavorites);
    log('query: $query');

    List<RobotAnimation> filteredList = searchList
        .where((element) =>
            element.title.toLowerCase().contains(query.toLowerCase()))
        .toList();

    log(searchList.toString());

    log(filteredList.toString());
    setState(() => animations = filteredList);
  }

  @override
  void initState() {
    animations = getAnimationList(results, defaultFavorites);
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return StoreConnector<AppState, _Props>(
      converter: (store) => _mapStateToProps(store),
      builder: (_, props) {
        return Scaffold(
          body: TabBarView(
            ...

                  children: [
                    TextField(
                      onChanged: filterSearchResults,
                      decoration: const InputDecoration(
                        labelText: 'Search',
                        hintText: 'Search animation',
