ios – How do I present operate as a parameter of struct

I am studying SwiftUI. So I’m creating climate app with @state toggling. I created button view however I am battling passing isDark.toggle operate as a parameter for my button view. I get Escaping autoclosure captures 'inout' parameter 'self'

I’ve my button view

struct WeatherButton: View {
    var textual content: String
    var motion: () -> Void
    
    init(textual content: String, motion: @escaping () -> Void) {
        self.textual content = textual content
        self.motion = motion
    }
    
    var physique: some View {
        Button(motion: {
            motion()
        }, label: {
            Textual content(textual content)
                .body(width: 280, top: 50)
                .background(.white)
                .font(.system(dimension: 20, weight: .daring))
                .cornerRadius(10)
        })
    }
}

and the way i exploit it

@State non-public var isDark = false

...

WeatherButton(textual content: "Theme toggle would not work",
                              motion: isDark.toggle)
