When making a gradient, I see quite a few examples using this, for instance:

endY =150.dp.toPx()

but I get "Unresolved Reference: toPx(). What am I doing wrong?

[Yann Badoual]

You need the density to resolve the px size

[Yann Badoual]

This can be done either in a DrawScope , or manually, you can also do with(DensityAmbient.current) { 150.dp.toPx() }

Ah ok, cheers! 😊

this whole process will ideally be a bit smoother once this API lands: https://android-review.googlesource.com/c/platform/frameworks/support/+/1426088/14/compose/ui/ui/samples/src/main/java/androidx/compose/ui/samples/DrawModifierSample.kt#41

[Adam Powell]

this will allow you to create and cache things like gradients across multiple draws, and the Density is available in that scope by default

[Nat Strangerweather]

Oh yeah, this looks ideal!

you won't have to worry about calls to remember {}, etc. for it
