How to set custom background color (instead of stroke) for Card in Jetpack Compose?

Question

Tell me how to set a background color for Card (Jetpack Compose). The trouble is, my card is not filled entirely, but it has a stroke: look at this image But I wanna fill this card entirely. How to do it?

I tried to fix this problem as written here, and wrote the code like this:

Card(modifier = Modifier.fillMaxWidth(),
            colors = CardDefaults.cardColors(containerColor = Blue1),
            shape = RoundedCornerShape(10.dp),
            elevation = CardDefaults.cardElevation(defaultElevation = 5.dp))

The color was called Blue1.

To set a background color for a Card in Jetpack Compose and ensure that the card is filled entirely, you can modify the code as follows:

Card(
    modifier = Modifier.fillMaxWidth()
        .background(Blue1, shape = RoundedCornerShape(10.dp)),
    elevation = 5.dp
) {
    // Content of the card
}
