弄了个本地的plugin， 在plugin里边 弄一个flutter页面， 想嵌套 iOS、Android 原生页面，不知道咋搞了， 大佬们有demo吗？ 参考一下

以下是一个简单的示例，演示如何在Flutter插件中嵌入原生iOS和Android视图： 1. 在Flutter插件中创建一个新的Flutter页面 ```dart import 'package:flutter/material.dart'; import 'package:flutter/services.dart'; class MyFlutterPage extends StatefulWidget { @override _MyFlutterPageState createState() => _MyFlutterPageState(); } class _MyFlutterPageState extends State { static const platform = MethodChannel('com.example.myplugin/native'); String _nativeMessage = ''; Future _getNativeMessage() async { String message; try { message = await platform.invokeMethod('getNativeMessage'); } on PlatformException catch (e) { message = "Failed to get native message: '${e.message}'."; } setState(() { _nativeMessage = message; }); } @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text('Flutter Page'), ), body: Center( child: Column( mainAxisAlignment: MainAxisAlignment.center, children: [ Text( 'This is a Flutter page', style: TextStyle(fontSize: 20), ), SizedBox(height: 20), ElevatedButton( onPressed: _getNativeMessage, child: Text('Get Native Message'), ), SizedBox(height: 20), Text(_nativeMessage), ], ), ), ); } } ``` 2. 在iOS原生代码中创建一个UIViewController，并将其添加到FlutterViewController中 ```swift import Flutter class MyNativeViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() let label = UILabel(frame: CGRect(x: 0, y: 0, width: 200, height: 50)) label.text = "This is an iOS view" label.textAlignment = .center label.center = view.center view.addSubview(label) } } class MyPlugin: NSObject, FlutterPlugin { static func register(with registrar: FlutterPluginRegistrar) { let channel = FlutterMethodChannel(name: "com.example.myplugin/native", binaryMessenger: registrar.messenger()) let instance = MyPlugin() registrar.addMethodCallDelegate(instance, channel: channel) let viewController =
