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.

Public fields

configUpdates

public final @NonNull Flow<@NonNull ConfigUpdate> configUpdates

Starts listening for config updates from the Remote Config backend and emits ConfigUpdates via a Flow. See FirebaseRemoteConfig.addOnConfigUpdateListener for more information.

When the returned flow starts being collected, an ConfigUpdateListener will be attached.
When the flow completes, the listener will be removed. If there are no attached listeners, the connection to the Remote Config backend will be closed.

remoteConfig

public final @NonNull FirebaseRemoteConfig remoteConfig

Returns the FirebaseRemoteConfig instance of the default FirebaseApp.
