    var body: some View {
        Button("Show Sheet") {
            showingSheet.toggle()
        }
        .sheet(isPresented: $showingSheet) {
            Text("Sheet Content")
                .font(.largeTitle)
                .padding()
                .background(Color.blue) // 设置背景色为蓝色
                .foregroundColor(.white)
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
