shadow

fun Modifier.shadow(
    elevation: Dp,
    shape: Shape = RectangleShape,
    clip: Boolean = elevation > 0.dp,
    ambientColor: Color = DefaultShadowColor,
    spotColor: Color = DefaultShadowColor
): Modifier

Creates a graphicsLayer that draws a shadow. The elevation defines the visual depth of the physical object. The physical object has a shape specified by shape.

If the passed shape is concave the shadow will not be drawn on Android versions less than 10.

Note that elevation is only affecting the shadow size and doesn't change the drawing order. Use a androidx.compose.ui.zIndex modifier if you want to draw the elements with larger elevation after all the elements with a smaller one.

Note that this parameter is only supported on Android 9 (Pie) and above. On older versions, this property always returns Color.Black and setting new values is ignored.

Usage of this API renders this composable into a separate graphics layer
