Will the system handle memory and resources cleanup? And will individual components be lifecycle aware? for example: dialogs

Now about activity/fragment life-cycle, but we have lifecycle aware effects, so you can init / cleanup some resources then component enters / leaves the composition. Something like

@Composable
fun UserRow(userId: Int) {
    val user = +state<User?> { null }
    +onActive {
        val dispose = Api.getUserAsync(userId) { user.value = it }
        onDispose { dispose() }
    }
    if (user.value == null) {
        LoadingIndicator()
    } else {
        Row {
            Image(src = user.value.profileImage)
            Text(text = user.value.name)
        }
    }
}

the final APIs is still TBD, but that's what we have right now

Cool, that was what I aimed for with me question
