Jetpack Glance: Add Linear Gradient to a Box Composable

I like to add a linear gradient to a Glance composable but it seems like there is no brush I can add like in Jetpack.

Box(
  modifier = GlanceModifier
    .background(//HERE)
    .fillMaxHeight()
    .cornerRadius(16.dp)
) {}

These are the constructors that are defined for background

GlanceModifier.background(Color) defined in androidx.glance
GlanceModifier.background(ImageProvider, ContentScale = ..., ColorFilter? = ...) defined in androidx.glance
GlanceModifier.background(ColorProvider) defined in androidx.glance
GlanceModifier.background(Int) defined in androidx.glance

I managed to implement it by using a Bitmap that I generate like Mike M. suggested.

private fun createGradientBitmap(
    width: Int,
    height: Int,
    startColor: Int,
    endColor: Int
): Bitmap {
    val bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888)
    val canvas = Canvas(bitmap)
    val paint = Paint()
    
    val gradient = LinearGradient(
        0f, 0f, width.toFloat(), 0f,
        startColor, endColor,
        Shader.TileMode.CLAMP
    )
    
    paint.shader = gradient
    canvas.drawRect(0f, 0f, width.toFloat(), height.toFloat(), paint)
    return bitmap
}

//...
@Composable
fun Gradient(
    modifier: GlanceModifier = GlanceModifier,
) { 
Box(
    modifier = GlanceModifier
    .fillMaxSize()
    .background(ImageProvider(gradientBitmap))
   ) {}
}
