如何从协程科特林获得价值？

我有一个用于用户登录的功能。但是它被暂停了。我尝试获取其返回值，但不能。这是我尝试做的

码

class LoginViewModel @ViewModelInject constructor(private val remoteDataSource: OrderRemoteDataSource) :
    ViewModel() {

    private fun areValidCredentials(username: String?, password: String?): Boolean {
        return username != null && password != null && username.length > 4 && password.length > 4
    }

    suspend fun login(username: String?, password: String?): Boolean {
        return suspendCoroutine { it ->
            val valid = areValidCredentials(username, password)
            if (valid) {
                // call finish so login activity won't show up after back button clicked in home fragment
                try {
                    viewModelScope.launch {
                        //TODO CHECK if error code
                        val loginResponse =
                            remoteDataSource.login(LoginRequest(username!!, password!!))
                        if (loginResponse.status == Resource.Status.SUCCESS) {
                            val jwtToken = loginResponse.data?.jwtToken
                            if (!jwtToken.isNullOrEmpty()) {
                                sessionManager.saveAuthToken(jwtToken!!)
                                //ERROR!
                                it.resume(true)
                            }

                        }
                    }
                } catch (e: Exception) {
                    Log.i("[LoginActivity]", e.localizedMessage!!)
                    it.resume(false)
                    e.printStackTrace()
                }
            } else {
                Toast.makeText(
                    LOGIN_ACTIVITY,
                    "Username and password must be at least 5 letters long",
                    Toast.LENGTH_SHORT
                ).show()
            }
            it.resume(false)
        }
    }
}

我称之为

@AndroidEntryPoint
class LoginFragment : Fragment() {
    private val mViewModel: LoginViewModel by viewModels()
    private lateinit var navController: NavController

    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View {
        return inflater.inflate(R.layout.frg_login, container, false)
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        Log.d("[LoginFragment]", "onCreate fun started!")

    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)

        navController = findNavController()
        loginButton.setOnClickListener {
            //TODO navigate to new fragmnet
            lifecycleScope.launch {
                mViewModel.login(
                    loginUsernameText.text.toString(),
                    loginPasswordText.text.toString()
                )
            }
        }
    }

而且我有错误

ZygoteInit.main（ZygoteInit.java:947）I / chatty：uid = 10163（ru.gkomega.navigation）相同的16行W / mega.navigatio：对不可取消优化的方法java.lang.Class java.lang提出了取消优化请求.Class.classForName（java.lang.String，boolean，java.lang.ClassLoader）I / Process：正在发送信号。PID：11863 SIG：9与目标VM断开连接，地址：“ localhost：58264”，传输：“ socket”

我对协程了解不多，所以可能是问题所在
