Code

public function transChoice($id, $number, array $parameters = [], $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));
