How to get language's full name from languageCode? (e.g: from 'en' to 'English')

0

I'm looking for the dart equivalent of this SO question/answer:
Get language name in that language from language code

In other words I'd rather avoid going manually one by one of checking if langCode=='en' return 'English' else if langCode == 'fr' return 'French' etc...

I tried looking for possible methods that do this in Locale, Intl, and Localizations classes, to no avail.

DropdownButton<String>(

            items: langCodesList.map((String value) {

              return DropdownMenuItem<String>(

                child: Text(value),

                value: value,

              );

            }).toList(),

            hint: Text(Localizations.localeOf(context).languageCode),

          ))

I want the DDL to display the full language name.
