Konfigure Firebase provides a simple implementation of a FirebaseRemoteConfig ConfigSource.
By default it uses the instance of FirebaseRemoteConfig returned by FirebaseRemoteConfig.getInstance(). You can specify your own by using the optional remoteConfig parameter in the primary constructor.
To use the FirebaseRemoteConfigSource, it's as easy as supplying it in the Config classes primary constructor
class AppConfig: Config(configSources = listOf(FirebaseRemoteConfigSource()))
