Its time to style the text in the Bullseye app. Material Design 3 provides us with different typography styles for common use cases. We can use them as they are, update them or create our own styles for text. Doing this is straightforward as you’ll see in the demo section. Let’s get into it.

  style = MaterialTheme.typography.labelLarge
style = MaterialTheme.typography.labelLarge.copy(fontSize = 20.sp)
@Preview(showBackground = true)
fun GamePromptPreview() {
  GamePrompt(targetValue = 50)
  style = MaterialTheme.typography.titleMedium.copy(letterSpacing = 1.sp, fontWeight = FontWeight.Bold) // New Code
//      "$targetValue",
  text = targetValue.toString(),
//      fontSize = 32.sp,
//      fontWeight = FontWeight.Bold,
  modifier = modifier.padding(8.dp),
  style = MaterialTheme.typography.displayMedium.copy(fontWeight = FontWeight.Bold)
