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.

MutationResult

Safe for concurrent use

All methods and properties of MutationResult are thread-safe and may be safely called and/or accessed concurrently from multiple threads and/or coroutines.

Not stable for inheritance

The MutationResult interface is not stable for inheritance in third-party libraries, as new methods might be added to this interface or contracts of the existing methods can be changed.
