Flutter Listview语言选择需要select上的圆形复选框设计

List<String> languages = ['Java', 'Python', 'JavaScript', 'C++', 'Ruby'];

List<bool> selectedLanguages = List<bool>.filled(languages.length, false);

ListView.builder(
  itemCount: languages.length,
  itemBuilder: (BuildContext context, int index) {
    return CheckboxListTile(
      title: Text(languages[index]),
      value: selectedLanguages[index],
      onChanged: (bool value) {
        setState(() {
          selectedLanguages[index] = value;
        });
      },
      controlAffinity: ListTileControlAffinity.leading, // 将复选框放在标题之前
      activeColor: Colors.blue, // 自定义选中时的颜色
      checkColor: Colors.white, // 自定义复选框的颜色
    );
  },
);
