Code

public function transChoice($id, $number, array $parameters = array(), $domain = NULL, $locale = NULL) {
  // Violation messages can separated singular and plural versions by "|".
  $ids = explode('|', $id);

  if (!isset($ids[1])) {
    throw new \InvalidArgumentException(sprintf('The message "%s" cannot be pluralized, because it is missing a plural (e.g. "There is one apple|There are @count apples").', $id));
  }

  // Normally, calls to formatPlural() need to use literal strings, like
  //   formatPlural($count, '1 item', '@count items')
  // so that the Drupal project POTX string extractor will correctly
  // extract the strings for translation and save them in a format that
  // formatPlural() can work with. However, this is a special case, because
  // Drupal is supporting a constraint message format from Symfony. So
  // although $id looks like a variable here, it is actually coming from a
  // static string in a constraint class that the POTX extractor knows about
  // and has processed to work with formatPlural(), so this specific call to
  // formatPlural() will work correctly.
  return \Drupal::translation()->formatPlural($number, $ids[0], $ids[1], $this->processParameters($parameters), $this->getOptions($domain, $locale));
