import com.example.coffecodersmexico.ui.components.CountryIso


//Navegando entre pantallas con compose
@Composable
fun DetailScreen(navController: NavController, countryIso: CountryIso){
    Column() {
        Text("Soy un producto de: ${countryIso.iso}", style = MaterialTheme.typography.h3)
        Button(onClick = {
            navController.navigate("feed"){
                popUpTo("feed")
            }

        }) {
            Text(text = "Volver")
        }
        
    }

}

@Preview(
    showBackground = true
)
@Composable
fun DetailScreenPreview(){
    val navController = rememberNavController()
    DetailScreen(navController, CountryIso.Bra)
}
