3. 10 core/modules/locale/src/LocaleConfigManager.php \Drupal\locale\LocaleConfigManager::translateString()

Translates string using the localization system.

So far we only know how to translate strings from English so the source string should be in English. Unlike regular t() translations, strings will be added to the source tables only if this is marked as default data.

Parameters

string $name: Name of the configuration location.

string $langcode: Language code to translate to.

string $source: The source string, should be English.

string $context: The string context.

Return value

string|false Translated string if there is a translation, FALSE if not.
