Defines an annotation object for strings that require plural forms.

Note that the return values for both 'singular' and 'plural' keys needs to be passed to \Drupal\Core\StringTranslation\TranslationInterface::formatPlural().

For example, the annotation can look like this:


  label_count = @ PluralTranslation(
    singular = "@count item",
    plural = "@count items",
    context = "cart_items",
  ),

Remove spaces after @ in your actual plugin - these are put into this sample code so that it is not recognized as annotation.

Code samples that make use of this annotation class and the definition sample above:

// Returns: 1 item
$entity_type->getCountLabel(1);
// Returns: 5 items
$entity_type->getCountLabel(5);
