Code
function _contextual_links_to_id($contextual_links) {
$ids = array();
$langcode = \Drupal::languageManager()->getCurrentLanguage(LanguageInterface::TYPE_URL)->getId();
foreach ($contextual_links as $group => $args) {
$route_parameters = UrlHelper::buildQuery($args['route_parameters']);
$args += ['metadata' => []];
// Add the current URL language to metadata so a different ID will be
// computed when URLs vary by language. This allows to store different
// language-aware contextual links on the client side.
$args['metadata'] += ['langcode' => $langcode];
$metadata = UrlHelper::buildQuery($args['metadata']);
$ids[] = "{$group}:{$route_parameters}:{$metadata}";
