Bullseye looks better but currently it has a plain white background. We can make that look better too. Let’s add a background image to make the app look more appealing.

Box {
  Column(
    //...
  ){
    //...
  }
}

Image(
  modifier = Modifier.fillMaxSize(),
  painter = painterResource(id = R.drawable.background),
  contentDescription = "Background Image"
)

Image(
  modifier = Modifier.fillMaxSize(),
  painter = painterResource(id = R.drawable.background),
  contentScale = ContentScale.Crop, // New Code
  contentDescription = stringResource(R.string.background_image)
)
