use JobMetric\Language\Facades\Language;

// Store
$response = Language::store([
    'name' => 'English',
    'flag' => 'us',
    'locale' => 'en',

$languages = Language::query(['status' => true])
    ->where('direction', 'rtl')
    ->orderBy('name')
    ->get();

// Pagination
$languages = Language::paginate(['status' => true], 20);

// With filters and sorts
$languages = Language::query()
    ->where('calendar', 'jalali')
    ->sort('name')
