clonethisrepository link with language pack for Laravel, copied the en-BR folder for resources / lang, I changed the locale and fallback_locale to pt-BR, however my page was not translated, only the validation messages!
This standard package translates only the validations and messages generated by laravel.
Blade messages are not translated by default, you also have to prepare your blade to be translated.
look here in the documentation that will clarify you better link
