Wrong mask being set after upgrade to version 1.2.1

[emersonsiega]

We are using this library in two different projects, applying masks for brazilian phone numbers.
The first one is using version 1.1.0 and the second started using this lib with version 1.2.1.
We notice that the mask is not being applied correctly in version 1.2.1.

With 1.1.0, the correct mask is: +55 (XX) XXXXX-XXXX
With 1.2.1, the wrong mask is +55 XXXXX-XXXX

We had to downgrade to version 1.1.0 in both projects.

Tested only in iOS, with latest Flutter version (stable).

This is how we are mounting the TextInputFormatter. It's the same code used in the two projects.

Future<void> init() async {
    if (_locales == null) {
      await FlutterLibphonenumber().init();

      _locales = await FlutterLibphonenumber().getAllSupportedRegions();
    }
}

TextInputFormatter? maskFor({String? countryCode = 'BR'}) {
    final country = _locales?[countryCode];

    if (country != null) {
      return LibPhonenumberTextFormatter(
        country: country,
        phoneNumberFormat: PhoneNumberFormat.national,
        phoneNumberType: PhoneNumberType.mobile,
      );
    }

    return null;
}

@emersonsiega This is a duplicate of the bug I already logged against national phone numbers in U.S. Issue 22. The latest version has a major bug with the .national phone number format.
