Namespace

Drupal\Core\Field\Plugin\Field\FieldFormatter

Code

protected function viewValue(FieldItemInterface $item) {

  // storage by LanguageManager::getLanguages()) or in its native language
  // name. That only depends on formatter settings and no language condition.
  $languages = $this

    ->getNativeLanguages(LanguageInterface::STATE_ALL) : $this->languageManager
    ->getLanguages(LanguageInterface::STATE_ALL);
