Issue in updating the state variable's value within the partial sheet's content

[khan33]

I'm having trouble updating the state variable's value within the partial sheet's content. The code below works well with SwiftUI's sheet view.

struct DemoView: View {

@State var buttonTxt: String = "Start"
@State var issheet: Bool = false
var body: some View {
    
    VStack {
        Button {
            issheet.toggle()
        } label: {
            Text("Button")
                .foregroundColor(Color.white)
                .padding()
                .background(Color.red)
        }
    }
    .partialSheet(isPresented: $issheet, content: {
        Button {
            buttonTxt = "Stop"
        } label: {
            Text(buttonTxt)
                .foregroundColor(Color.white)
                .frame(width: 180, height: 55)
                .padding()
                .background(Color.red)

        }
    })
    .padding()
}

}
