class SettingsViewModelFactory(application: Application, owner: SavedStateRegistryOwner) : SavedStateViewModelFactory(application, owner){


    override fun <T : ViewModel?> create(modelClass: Class<T>): T {
        if (modelClass.isAssignableFrom(SettingsViewModel::class.java)){
            return SettingsViewModel() as T
        }
        throw IllegalArgumentException("Invalid ViewModel class")
    }

}

我在 SavedStateViewModelFactory 下方看到一条红色下划线，表示该类型是最终类型，不能继承。我该怎么办？文档太模糊了。另外我要在退货中放入什么状态？
