我是 Swift/SwiftUI 新手，想知道如何从嵌套子视图中消除模式/页面。

首先，我从 Flutter、UIHostingController、然后 SwiftUI 页面调用。（当前显示为模态...）
\n导航到 SwiftUI 后，我无法从子视图中使用 @environment 数据。

有什么办法可以做到这一点吗？\n提前致谢。

AppDelegate.swift

@UIApplicationMain\n@objc class AppDelegate: FlutterAppDelegate {\n    override func application(\n        _ application: UIApplication,\n        didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?\n    ) -> Bool {\n        let controller : FlutterViewController = self.window?.rootViewController as! FlutterViewController\n        let channel = FlutterMethodChannel.init(name: "com.example.show", binaryMessenger: controller.binaryMessenger)\n        channel.setMethodCallHandler({\n            (call, result) -> Void in\n            if call.method == "sample" {\n                let vc = UIHostingController(rootView: ContentView())\n                vc.modalPresentationStyle = .fullScreen\n                controller.present(vc, animated: true,completion: nil)\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n

内容视图.swift

struct ContentView: …
