Ternary operator

String value = when(storeType == StoreType.Database){
   true -> getDatabase().getSettingsDao().getString("my value")
   false ->  getSettingsHelper().getSharedPreferences().getString("my value")
}

//misuse takeIf, but it looks more like your code
String value = takeIf{ storeType == StoreType.Database }
    ?.let{ getDatabase().getSettingsDao().getString("my value") }
    ?: getSettingsHelper().getSharedPreferences().getString("my value")

I personally use when most of the time.
