SwiftUI -如何在返回导航时取消初始化StateObject？

class DataManager: ObservableObject {
    @Published var data: String = ""
}

struct ContentView: View {
    @StateObject private var dataManager = DataManager()
    @State private var isInitialized = false

    var body: some View {
        NavigationView {
            VStack {
                Text(dataManager.data)
                    .padding()
                Button("Initialize") {
                    isInitialized = true
                }
                .padding()
                NavigationLink("Back", destination: DetailView(dataManager: $dataManager, isInitialized: $isInitialized))
                    .padding()
            }
        }
    }
}

struct DetailView: View {
    @Binding var dataManager: DataManager
    @Binding var isInitialized: Bool

    var body: some View {
        VStack {
            Text("Detail View")
                .padding()
            if isInitialized {
                Text("Data initialized")
                    .padding()
            }
        }
        .onDisappear {
            if !isInitialized {
                dataManager = DataManager()
            }
        }
    }
}
