BackgroundModifier¶

data class BackgroundModifier(
    val startColor: Int, 
    val endColor: Int, 
    val gradientDirection: GradientDirection = GradientDirection.TOP_TO_BOTTOM
) : Modifier.Element<BackgroundModifier> , DrawModifier

A DrawModifier that fills a composable's background with a solid colour or a two-stop linear gradient.

When startColor and endColor are equal the fill is solid; otherwise the two colours are interpolated across the node bounds in gradientDirection.
