当键盘显示且列表像聊天应用程序一样位于底部时，如何插入SwiftUI列表

import SwiftUI

struct ContentView: View {
    @State private var messages: [String] = []
    @State private var newMessage: String = ""
    @State private var scrollToBottom: Bool = false

    var body: some View {
        VStack {
            ScrollViewReader { scrollViewProxy in
                ScrollView {
                    LazyVStack {
                        ForEach(messages, id: \.self) { message in
                            Text(message)
                                .padding()
                        }
                    }
                    .onChange(of: scrollToBottom) { value in
                        if value {
                            scrollViewProxy.scrollTo(messages.count - 1, anchor: .bottom)
                            scrollToBottom = false
                        }
                    }
                }
            }
            
            HStack {
                TextField("Enter a message", text: $newMessage)
                    .textFieldStyle(RoundedBorderTextFieldStyle())
                    .padding()
                
                Button(action: {
                    messages.append(newMessage)
                    newMessage = ""
                    scrollToBottom = true
                }) {
                    Text("Send")
                        .padding()
                        .background(Color.blue)
                        .foregroundColor(.white)
                        .cornerRadius(10)
                }
            }
            .padding()
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
