The application has english as a default language. If you want to change the default language, you can change it in applocalitations_provider.dart file. The file is in lib/provider/applocalitations_provider.dart directory folder. Change the value of appLocale with the language code. For example : ‘en’ for english, ‘es’ for espanyol, and ‘id’ for indonesia. And also change the fetchLocale() at appLocale variable too.
