<string name="result_dialog_message">The slider\'s value is %1$d.\nYou scored %2$d points this round.</string>
fun ResultDialog(
  hideDialog: () -> Unit,
  sliderValue: Int,
  points: Int, // New Code
  modifier: Modifier = Modifier
) {
    text = { Text(stringResource(id = R.string.result_dialog_message, sliderValue, points)) } // Updated Code with points
  hideDialog = { alertIsVisible = false },
  sliderValue = sliderToInt,
  points = pointsForCurrentRound() // New Code
