Currently, the Bullseye app generates a target value for the player to aim for. The player can then move the slider as close as they can to the target value then tap the 鈥淗it Me鈥 button.

fun pointsForCurrentRound(): Int {
    return 999
}
<string name="result_dialog_message">The slider\'s value is %1$d.\nYou scored %2$d points this round.</string>
@Composable
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
}
ResultDialog(
  hideDialog = { alertIsVisible = false },
  sliderValue = sliderToInt,
  points = pointsForCurrentRound() // New Code
)
