如何根据SwiftUI中另一个视图的变量显示(在ContentView中)视图？

struct ContentView: View {
    @State private var showDetails = false
    
    var body: some View {
        VStack {
            Button(action: {
                self.showDetails.toggle()
            }) {
                Text("Toggle Details")
            }
            
            if showDetails {
                DetailView(showDetails: $showDetails)
            }
        }
    }
}

struct DetailView: View {
    @Binding var showDetails: Bool
    
    var body: some View {
        Text("Details")
            .onTapGesture {
                self.showDetails = false
            }
    }
}
