无法创建类的实例 |带有（应用程序：应用程序）参数的 ViewModel

Question

我试图从 DetailUserViewModel 传递参数并最终收到错误“无法创建类的实例”，如果我删除参数（应用程序：应用程序），应用程序正在运行。

感谢任何答案，因为它帮助我完成了期末考试。 非常感谢。

这是我的代码块：

DetailUserViewModel

class DetailUserViewModel(application: Application): ViewModel() {

    private val userRepository: UserRepository = UserRepository(application)

    private val _userDetail = MutableLiveData<DetailUserResponse>()
    val userDetail: LiveData<DetailUserResponse> = _userDetail

    private val _listFollows = MutableLiveData<List<Item>>()
    val listFollows: LiveData<List<Item>> = _listFollows

    private val _isLoading = MutableLiveData<Boolean>()
    val isLoading: LiveData<Boolean> = _isLoading

    fun insert(user: User){
        userRepository.insertUser(user)
    }

    fun delete (user: User){
        userRepository.delete(user)
    }

    fun getUserFavoritesById(id: Int): LiveData<List<User>>{
        return userRepository.getUserFavoritesById(id)
    }



    fun setUserDetail(username: String) {
        showLoading(true)
        val client = ApiConfig.getApiService().getDetailUser(username)
        client.enqueue(object : Callback<DetailUserResponse> {
            override fun onResponse(
                call: Call<DetailUserResponse>,
                response: Response<DetailUserResponse>
            ) {
                if (response.isSuccessful) {
                    showLoading(false)
                    val responseBody = response.body()
                    if (responseBody != null) {
                        _userDetail.value = responseBody
                    }
                }
            }

            override fun onFailure(call: Call<DetailUserResponse>, t: Throwable) {
                Log.e("Failure", "${t.message}")
            }
        })
    }

    fun getFollowers(username: String) {
        showLoading(true)
        val client = ApiConfig.getApiService().getFollowers(username)
        client.enqueue(object : Callback<List<Item>> {
            override fun onResponse(call: Call<List<Item>>, response: Response<List<Item>>) {
                if (response.isSuccessful) {
                    showLoading(false)
                    val responseBody = response.body()
                    if (responseBody != null) {
                        _listFollows.value = responseBody
                    }
                }
            }

            override fun onFailure(call: Call<List<Item>>, t: Throwable) {
                Log.e("Failure", "${t.message}")
            }

        })
    }

    fun getFollowing(username: String) {
        showLoading(true)
        val client = ApiConfig.getApiService().getFollowing(username)
        client.enqueue(object : Callback<List<Item>> {
            override fun onResponse(call: Call<List<Item>>, response: Response<List<Item>>) {
                if (response.isSuccessful) {
                    showLoading(false)
                    val responseBody = response.body()
                    if (responseBody != null) {
                        _listFollows.value = responseBody
                    }
                }
            }

            override fun onFailure(call: Call<List<Item>>, t: Throwable) {
                Log.e("Failure", "${t.message}")
            }

        })
    }

    private fun showLoading(b: Boolean) {
        if (b) {
            _isLoading.value = true
        } else {
            _isLoading.value = false
        }
    }
