Use Device Language

Use the useDeviceLanguage method to manually set the Firebase Authentication language to a specific language provided by the developer.

Method

final language = await FirebaseApp.firebaseAuth?.useDeviceLanguage(userId, languageCode);

Parameters

  • userId (String): The unique user ID for which the language setting is to be applied.

  • languageCode (String): The language code (e.g., 'en', 'fr') to set as the Firebase Authentication language.

Return

  • String?: Returns the language code that was set.

This method allows developers to explicitly set the language used by Firebase Authentication for operations such as email templates and SMS messages.
