我使用的是def lifecycle_version = "2.3.1"，
implementation("androidx.lifecycle:lifecycle-viewmodel-ktx:$lifecycle_version") .
但是我必须将版本更新到def lifecycle_version = "2.4.0-alpha03"才能使用某些特性，但是在我使用def lifecycle_version = "2.4.0-alpha03"之后，ViewModelProvider.Factory类不起作用。

class ViewModelFactory(private val param:String,private val param2: String) : ViewModelProvider.Factory {
    override fun <T : ViewModel?> create(modelClass: Class<T>): T {
        return if (modelClass.isAssignableFrom(ReviewViewModel::class.java)) {
            ReviewViewModel(param,param2) as T
        }else if(modelClass.isAssignableFrom(FoodViewModel::class.java)){
            FoodViewModel(param,param2) as T
        else {
            throw IllegalArgumentException()
        }
    }
}

错误消息为
！Class 'ViewModelFactory' is not abstract and does not implement abstract member public abstract fun <T : ViewModel> create(modelClass: Class<T>): T defined in androidx.lifecycle.ViewModelProvider.Factory
！'create' overrides nothing个字符
谢谢你
