How to pass parameter to my hilt viewmodel from jetpack compose

Question

I have a composable with viewmodel and I want to pass an id from the composable to the viewmodel.

My composable is:

@Composable
fun HttpRequestScreen(
    viewModel: HttpRequestViewModel = hiltViewModel(),
    id: String = EMPTYUUID,
    onClick: (String, String, Int) -> Unit // respond, request Function: 1 - send request, 2 - edit request
) {

I have the id from a different screen and I want to pass it to my Hilt viewmodel.

Assuming that you have followed the documentation for compose navigation, you can find your parameter here:

@HiltViewModel
class RouteDetailsViewModel @Inject constructor(
    private val getRouteByIdUC: GetRouteByIdUC,
    private val savedStateHandle: SavedStateHandle
): ViewModel() {

    private val routeId = savedStateHandle.get<String>("your-param-name") // for example String in my case
}
