Is it possible to access MaterialTheme.colorScheme from non-composable?

@Stable
val largeRadialGradient = object : ShaderBrush() {
    override fun createShader(size: Size): Shader {
        val biggerDimension = maxOf(size.height, size.width)
        return RadialGradientShader(
            colors = listOf(
               MaterialTheme.colorScheme.primary,... // access colorScheme here
            ),
            center = size.center,
            radius = biggerDimension,
            colorStops = listOf(
                0f,
                0.5f,
                0.8f,
            ),
        )
    }
}

@Lilly if colorScheme is a @Composable then no

[Lilly]

Obvious, but the color scheme can be accessed in another way, I guess

MaterialTheme gets colorScheme through

staticCompositionLocalOf

so you can access it only inisde the tree.
But well, the Colour itself is not Composable so If you save it additionally somewhere, you can get if from there

Material library does this by defining some tokens, and then has a composable function that maps from those tokens to the actual color https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/[…]944?q=fromToken&ss=androidx%2Fplatform%2Fframeworks%2Fsupport. You might be able to just do the same if you need to do this.

Thanks guys. I found Brush.radialGradient() which is satisfying too
