Important: In July 2025, we stopped releasing KTX modules and removed the KTX libraries from the Firebase Android BoM (v34.0.0). If you use KTX APIs from the 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.
