以下是一个简单的示例,演示如何在Flutter页面中嵌入iOS和Android原生页面。
首先,在Flutter插件中创建一个新的Flutter页面。例如,我们可以创建一个名为`NativePage`的Flutter页面:
```dart
import 'package:flutter/material.dart';
class NativePage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Native Page'),
),
body: Center(
child: Text('This is a Flutter page.'),
),
);
}
}
```
接下来,我们需要在iOS和Android原生代码中实现一个方法,该方法将打开Flutter页面并将其嵌入到原生视图中。
在iOS中,我们可以使用`FlutterViewController`来打开Flutter页面,并使用`addSubview`方法将其添加到原生视图中。以下是一个示例方法:
```swift
func openFlutterPage() {
let flutterEngine = (UIApplication.shared.delegate as! AppDelegate).flutterEngine
let flutterViewController = FlutterViewController(engine: flutterEngine, nibName: nil, bundle: nil)
self.addChild(flutterViewController)
flutterViewController.view.frame = self.view.bounds
self.view.addSubview(flutterViewController.view)
flutterViewController.didMove(toParent: self)
}
```
在Android中,我们可以使用`FlutterFragment`来打开Flutter页面,并使用`getChildFragmentManager`方法将其添加到原生视图中。以下是一个示例方法:
```java
private void openFlutterPage() {
FlutterEngine flutterEngine = ((MyApplication) getApplication()).getFlutterEngine();
FlutterFragment flutterFragment = FlutterFragment.withNewEngine()
.initialRoute("native_page")
.build();
getSupportFragmentManager()
.beginTransaction()
.add(R.id.container, flutterFragment)
.commit();
}
```
最后,在Flutter插件中,我们需要将`NativePage`页面注册为路由。这样,当我们从原生代码打开Flutter页面时,我们可以使用该路由名称来打开`NativePage`页面。
```dart
import 'package:flutter/material.dart';
class NativePage extends StatelessWidget {
static const String routeName = '/native_page'; // 注册路由名称
