如何像flutter中选中的chips一样获取未选中（unselected）的chips？

我使用Map功能构建了多选芯片。当选择一个芯片时，颜色会变成黄色。当选定芯片后，然后打印选定的芯片。就像这样，我想选择芯片并显示其中取消选择的芯片。能做到吗？如果可以如何实施？

code:

List<String> hobbyList = [
    'Shopping',
    'Brunch',
    'Music',
    'Road Trips',
    'Tea',
    'Trivia',
    'Comedy',
    'Clubbing',
    'Drinking',
    'Wine',
  ];

  List<String>? selectedHobby = [];

Column(
                        children: <Widget>[
                          const SizedBox(height: 16),
                          Wrap(
                            children: hobbyList.map(
                              (hobby) {
                                bool isSelected = false;
                                if (selectedHobby!.contains(hobby)) {
                                  isSelected = true;
                                }
                                return GestureDetector(
                                  onTap: () {
                                    if (!selectedHobby!.contains(hobby)) {
                                      if (selectedHobby!.length < 50) {
                                        selectedHobby!.add(hobby);
                                        setState(() {});
                                        print(selectedHobby);
                                      }
                                    } else {
                                      selectedHobby!.removeWhere(
                                          (element) => element == hobby);
                                      setState(() {});
                                      print(selectedHobby);
                                    }
                                  },
                                  child: Container(

                                    child: Container(
                                      padding: const EdgeInsets.symmetric(
                                          vertical: 5, horizontal: 12),
                                      decoration: BoxDecoration(
                                          color: isSelected
                                              ? HexColor('#F5F185')

                                          borderRadius:
                                              BorderRadius.circular(18),
                                          border: Border.all(
                                              color: isSelected
                                                  ? HexColor('#F5F185')
                                                  : HexColor('#D9D9D9'),
                                              width: 2)),
                                      child: Text(
                                        hobby,
                                        style: TextStyle(
                                            color: isSelected
                                                ? Colors.black
                                                : Colors.black,

                                      ),
                                    ),
                                  ),
                                );
                              },
                            ).toList(),
                          ),
                        ],
                      ),

选定的项目显示如下。在此输入图像描述

像这样如何显示取消选择的项目？

实现此目的的更好方法是创建自定义类

class chipsSelected{
  String? title;
  bool isSelected;
  chipsSelected({this.title,this.isSelected=false});
}

=> 在列表中添加数据

List<chipsSelected> hobbyList = [
    chipsSelected(title: 'Shopping',isSelected: false),
    chipsSelected(title: 'Brunch',isSelected: false),
    chipsSelected(title: 'Music',isSelected: false),
    chipsSelected(title: 'Road Trips',isSelected: false),
    chipsSelected(title: 'Tea',isSelected: false),
    chipsSelected(title:  'Trivia',isSelected: false),
    chipsSelected(title: 'Comedy',isSelected: false),
    chipsSelected(title:  'Clubbing',isSelected: false),
    chipsSelected(title: 'Drinking',isSelected: false),
    chipsSelected(title: 'Wine',isSelected: false),
                                    ];

  List<chipsSelected> selectedHobby = [];

=> 显示

Column(
              children: <Widget>[
                const SizedBox(height: 16),
                Wrap(
                  children: hobbyList.map(
                        (hobby) {
                          var s=hobbyList.where((element) => element.title==hobby.title).first;
                      return GestureDetector(
                        onTap: () {
                          setState(() {
                            var clickedHobbyList=hobbyList.where((element) => element.title==hobby.title).first;
                            clickedHobbyList.isSelected=!hobby.isSelected;
                          });
                          print("Selected");
