如何在其中传递 navController 参数？

我对 jetpack compose kotlin 有点陌生。这是我的登录屏幕函数，它需要 2 个参数：

fun loginScreen(
        navController: NavController,
        onClick: (mobileNum: String, otp: String) -> Unit
    ) {
       //my_code
      }

这是我的 navhost 函数

composable(route = Screen.Loginscreen.route){loginScreen(navController = navController,onClick = {mobileNum, otp ->  })}

这是我调用该函数的地方。我如何在这里传递 navController ？ class LoginScreenActivity:ComponentActivity() {

@RequiresApi(Build.VERSION_CODES.M)

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContent {
        Surface(color = MaterialTheme.colors.background) {
            loginScreen {

                mobileNum, otp ->
                if (mobileNum.isNotEmpty()) {
                    send(mobileNum)
                }

            }

//其余代码

如果需要进一步详细说明，请告诉我。TIA

I'm kinda new to jetpack compose kotlin.This is my login screen function which takes 2 parameters:

fun loginScreen(
        navController: NavController,
        onClick: (mobileNum: String, otp: String) -> Unit
    ) {
       //my_code
      }

This is my navhost function

composable(route = Screen.Loginscreen.route){loginScreen(navController = navController,onClick = {mobileNum, otp ->  })}

This is where I call the function. How do I pass the navController here??
class LoginScreenActivity:ComponentActivity() {

@RequiresApi(Build.VERSION_CODES.M)

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContent {
        Surface(color = MaterialTheme.colors.background) {
            loginScreen {

                mobileNum, otp ->
                if (mobileNum.isNotEmpty()) {
                    send(mobileNum)
                }

            }

//rest of the code

Let me know if I need to elaborate further.TIA
