How to disable shadow rotation in my example? I mean "sun" must be always at the top of the object.

Thanks for 100 days of swiftUI!

struct ShadowView: View {
    @State private var angle = 0.0
    var body: some View {

        Button(action: {

            withAnimation {
                self.angle += 30

            }
        }) {

        VStack{

                Rectangle()
                    .foregroundColor(Color.green)
                    .frame(width: 100, height: 100, alignment: .center)
                    .rotationEffect(Angle(degrees: self.angle))
            }.shadow(color: Color.black, radius: 50, x: 0, y: 50)

        }

    }
}

Noone knows?
