我创建自定义阴影与修改器扩展功能。它在其他Android版本上提供了完美的输出。但一些较旧的Android版本，如Android OS版本6，它没有显示任何阴影。修改器扩展函数看起来像这样：

fun Modifier.advancedShadow() = composed {
    val color = Color.SomeColor
    drawBehind {
        val shadowColor = color.copy(alpha = 0.10f).toArgb()
        val transparentColor = Color.Black.copy(alpha = 0f).toArgb()
        drawIntoCanvas {
            val paint = Paint()
            val frameworkPaint = paint.asFrameworkPaint()
            frameworkPaint.color = transparentColor
            frameworkPaint.setShadowLayer(
                12.dp,
                0.dp,
                1.dp,
                shadowColor
            )
            it.drawRoundRect(
                0f,
                0f,
                this.size.width,
                this.size.height,
                cornerRadius.toPx(),
                cornerRadius.toPx(),
                paint
            )
        }
    }
}
