To change locale you can use and setLang method in your root or boot project:

<?php

declare(strict_types=1);

require __DIR__.'/vendor/autoload.php';

use Hsnfirdaus\ClassValidator\Validator;

Validator::setLang('id');

// Then you can call  Validator::validate method

Or, you can use your own locale with setLangDir method. For example, create your locale file in __DIR__.'/locale/kr.php, then you can use:

Validator::setLangDir(__DIR__.'/locale');
Validator::setLang('kr');
