IMPORTANT: In July 2025, we stopped releasing new versions of KTX modules, and we removed the KTX libraries from the Firebase Android BoM (v34.0.0). If you use KTX APIs from the previously released KTX modules, we recommend that you
migrate your app to use KTX APIs from the main modules instead. For details, see the
FAQ about this initiative.
