如何将String值赋给环境对象--错误:无法将‘TextField’类型的值转换为所需的参数类型‘Binding<String>’“

import SwiftUI

struct ContentView: View {
    @State private var text: String = ""

    var body: some View {
        VStack {
            TextField("Enter text", text: $text)
                .padding()
            
            // 将String值赋给环境对象
            ChildView()
                .environment(\.myEnvironmentObject, $text)
        }
    }
}

struct ChildView: View {
    @Environment(\.myEnvironmentObject) private var text: Binding<String>

    var body: some View {
        Text(text.wrappedValue)
    }
}

// 自定义环境键
struct MyEnvironmentKey: EnvironmentKey {
    static let defaultValue: Binding<String> = .constant("")
}

// 扩展EnvironmentValues，添加自定义环境对象
extension EnvironmentValues {
    var myEnvironmentObject: Binding<String> {
        get { self[MyEnvironmentKey.self] }
        set { self[MyEnvironmentKey.self] = newValue }
    }
}
