您可以通过保留生命周期观察器的DiposableEffect并检查启动回调来访问登录屏幕中的Intent、主编写函数，当我们将Activity launchMode="singleTask"保留在清单中时，onNewIntent将触发。

val context = LocalContext.current
val lifecycleOwner: LifecycleOwner = LocalLifecycleOwner.current
//handle deepLinks/noti. in home screen
DisposableEffect(lifecycleOwner) {
   
   
    // Create an observer that triggers our remembered callbacks
    // for sending analytics events
    val observer = LifecycleEventObserver { _, event ->
        if (event == Lifecycle.Event.ON_START) {
           val activity = context.findActivity()
    val intent = activity?.intent
    val destination = intent?.getStringExtra("destinationScreen")
    val queryParameter = intent?.data?.getQueryParameter("destinationScreen")
           //send this data to your viewmodel
        }
    }

    // Add the observer to the lifecycle
    lifecycleOwner.lifecycle.addObserver(observer)

    // When the effect leaves the Composition, remove the observer
    onDispose {
        lifecycleOwner.lifecycle.removeObserver(observer)
    }
}

下面是findActivity扩展函数。

fun Context.findActivity(): Activity? = when (this) {
is Activity -> this
is ContextWrapper -> baseContext.findActivity()
else -> null

}
