02/02/2021, 2:18 PMHi again. I'm trying to build a Canvas, but I don't know how. I've been looking at https://developer.android.com/reference/kotlin/androidx/compose/ui/graphics/Canvas, but Canvas is an interface, and I don't know if there is a class implementing it.

// Call drawing functionsI am unsure if this fits your exact needs, but might be a good starting point 🙂

02/02/2021, 3:09 PMThank you very much 🙂 Also, I think I had the wrong import : I should use
import androidx.compose.foundation.CanvasFinally this worked :)
