How can I implement AppTranslations widget with checkbox?, I want to select one of the language by click on the box on the right side of the listtile

I try use CheckBoxListTilie but without success :(

i want something like this:

code:

class _LanguageSelectorState extends State<LanguageSelector> {
  static final List<String> languagesList = application.supportedLanguages;
  static final List<String> languageCodesList =
      application.supportedLanguagesCodes;


  final Map<dynamic, dynamic> languagesMap = {
    languagesList[0]: languageCodesList[0],
    languagesList[1]: languageCodesList[1],
  };

  @override
  Widget build(BuildContext context) {
    return Scaffold(
          backgroundColor: Colors.white,
          appBar: AppBar(
            backgroundColor: Colors.white,
            iconTheme: IconThemeData(color: Colors.black),
            title: Text(AppTranslations.of(context).text("settings_language"), style: TextStyle(color: Colors.black, letterSpacing: 1)),
            elevation: 0.0,
            centerTitle: true,
            bottom: PreferredSize(child: Container(color: Colors.black, height: 0.1), preferredSize: Size.fromHeight(0.1),),
          ),
      body: _buildLanguagesList(),
    );
  }

  String selectedLanguage = '';

  _buildLanguagesList() {
    return ListView.builder(
      itemCount: languagesList.length,
      itemBuilder: (context, index) {
        return _buildLanguageItem(languagesList[index]);
      },
    );
  }

  _buildLanguageItem(String language) {
    return ListTile(
      onTap: () {
        selectedLanguage = language;
        application.onLocaleChanged(Locale(languagesMap[language]));
      },
      title: Text(language),
      leading: Icon(Icons.flag),
    );
