I'm following a Room tutorial for Kotlin and (at about 40 minutes) I get the following error:

Below is my code (I checked it and it seems exactly how shown in the video)

@Composable
fun AddContactDialog(
    state: ContactState,
    onEvent: (ContactEvent) -> Unit,
    modifier: Modifier = Modifier
){
    AlertDialog(
        modifier = modifier,
        onDismissRequest = {
            onEvent(ContactEvent.HideDialog)
        },
        title = { Text(text = "Add contact") },
        text = {
            Column(

                        onEvent(ContactEvent.SetFirstName(it))

                    }
                )
                TextField(

androidx.appcompat.app.AlertDialog is not the correct import, AlertDialog is a composable and is imported like this:

import androidxpose.material3.AlertDialog

There are now multiple AlertDialog composables available (one is deprecated), but none that matches the parameters you provided. The one you want needs a confirmButton parameter instead of the buttons parameter. Just rename the parameter accordingly and everything should work fine.
