Flutter Firebase Authentication With Riverpod

Question

By reading the documentation of riverpod I wanted to redo the example of the section "third party examples" the example is "firebase phone auth with riverpod" here is the link:https://docs-v2.riverpod.dev/docs/getting_started ; and the github repository is the following:https://github.com/julienlebren/flutter_firebase_phone_auth_riverpod; I would like to load the list of countries and their area code to be able to choose a country and enter a corresponding number but my code does not load anything.

I modified the code to comply with null safety and here is my github code in the authenticationWithProvider branch:https://github.com/jordanSinde/com_akdemix/tree/authenticationWithProvider; at compile time, the code does not display anything when loading the list of countries and their area codes so instead of having this enter image description here I rather have this enter image description here; here is the function which aims to load this list

Future<void> _loadCountries() async {
    try {
      await FlutterLibphonenumber().init();
      var countries = CountryManager().countries;
      countries.sort((a, b) {
        return a.countryName!
            .toLowerCase()
            .compareTo(b.countryName!.toLowerCase());
      });
      countries = countries;

      final langCode = ui.window.locale.languageCode.toUpperCase();
      _firebaseAuth.setLanguageCode(langCode);

      var filteredCountries =
          countries.where((item) => item.countryCode == langCode);

      if (filteredCountries.isEmpty) {
        filteredCountries = countries.where((item) => item.countryCode == 'US');
      }
      if (filteredCountries.isEmpty) {
        throw Exception('Unable to find a default country!');
      }
      setCountry(filteredCountries.first);
    } catch (e) {
      state = AuthState.error(e.toString());
    }
  }

void setCountry(CountryWithPhoneCode selectedCountry) {
    _selectedCountry = selectedCountry;
    state = AuthState.ready(selectedCountry);
  }

  Future<void> parsePhoneNumber(String inputText) async {
    _phoneNumber = await FlutterLibphonenumber().parse(
      "+${_selectedCountry.phoneCode}${inputText.replaceAll(RegExp(r'[^0-9]'), '')}",
      region: _selectedCountry.countryCode,
    );
    if (_phoneNumber['type'] != 'mobile') {
      throw Exception('You must enter a mobile phone number.');
    }
  }

the package used is flutter_libphonenumber; on the other hand the console does not show me any error enter image description here; and this is how i called the provider watch provider . what is wrong with my function please. Thanks for the reading.
