class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            Tugasppb4Theme {
                Surface(
                    modifier = Modifier.fillMaxSize(),
                    color = MaterialTheme.colorScheme.background
                ) {
                    DiceRollerApp()
                }
            }
        }
    }
}

@Preview
@Composable
fun DiceRollerApp(){
    DiceWithButtonAndImage(modifier = Modifier
        .fillMaxSize()
        .wrapContentSize(Alignment.Center))
}

@Composable
fun DiceWithButtonAndImage(modifier: Modifier = Modifier) {
    var result by remember {
        mutableIntStateOf(1)
    }
    val imageResource = when(result) {
        1 -> R.drawable.dice_1
        2 -> R.drawable.dice_2
        3 -> R.drawable.dice_3
        4 -> R.drawable.dice_4
        5 -> R.drawable.dice_5
        else -> R.drawable.dice_6
    }
    Column (
        horizontalAlignment = Alignment.CenterHorizontally,
        modifier = Modifier
            .fillMaxSize()
            .wrapContentSize(Alignment.Center)
    ) {
        Image(painter = painterResource(id = imageResource),
              contentDescription = result.toString())
        Button(onClick = { result = (1..6).random() }){
            Text(stringResource(R.string.roll))
        }
    }
}

Hasil akhir:
