HarmonyOS 鸿蒙Next工程中进入flutter指定页面如何传参
HarmonyOS 鸿蒙Next工程中进入flutter指定页面如何传参 鸿蒙工程和flutter混编,鸿蒙工程进入到flutter指定页面如何给flutter页面传参,比如:要进入flutter版的订单详情页,需要给订单详情页传订单ID,要如何实现?下面是我在鸿蒙工程中使用的到代码:
router.pushUrl({ url: 'pages/myFlutter', params: { route: '/orderDetaill' } })
import { FlutterPage } from '@ohos/flutter_ohos'
import Log from '@ohos/flutter_ohos/src/main/ets/util/Log';
import FlutterEntry from '@ohos/flutter_ohos/src/main/ets/embedding/ohos/FlutterEntry';
import { FlutterView } from '@ohos/flutter_ohos/src/main/ets/view/FlutterView';
import router from '@ohos/router';
@Entry
@Component
struct MyFlutter {
private flutterEntry: FlutterEntry | null = null;
private flutterView?: FlutterView
aboutToAppear() {
Log.d("Flutter", "Index aboutToAppear===");
this.flutterEntry = new FlutterEntry(getContext(this), router.getParams() as Record<string, Object>)
this.flutterEntry.aboutToAppear()
this.flutterView = this.flutterEntry.getFlutterView()
this.flutterView.addFirstFrameListener(this)
}
onFirstFrame() {
}
aboutToDisappear() {
Log.d("Flutter", "Index aboutToDisappear===");
this.flutterEntry?.aboutToDisappear()
}
onPageShow() {
Log.d("Flutter", "Index onPageShow===");
this.flutterEntry?.onPageShow()
}
onPageHide() {
Log.d("Flutter", "Index onPageHide===");
this.flutterEntry?.onPageHide()
}
build() {
FlutterPage({ viewId: this.flutterView?.getId() })
}
}

在HarmonyOS鸿蒙Next工程中,如果你希望在Flutter应用中进入指定页面并传递参数,可以通过以下方式进行:
-
路由配置: 首先,在Flutter的路由配置中,你需要为目标页面定义一个路由名称。这通常在
MaterialApp
或CupertinoApp
的routes
属性中进行设置。 -
参数传递: 使用
Navigator.pushNamed
方法时,可以通过arguments
参数传递数据。例如:Navigator.pushNamed( context, 'yourRouteName', arguments: { 'key1': 'value1', 'key2': 123, }, );
-
接收参数: 在目标页面的
onGenerateRoute
或build
方法中,可以通过ModalRoute.of(context).settings.arguments
获取传递的参数。例如:class YourTargetPage extends StatelessWidget { @override Widget build(BuildContext context) { final Map<String, dynamic> args = ModalRoute.of(context).settings.arguments as Map<String, dynamic>; final String value1 = args['key1'] as String; final int value2 = args['key2'] as int; // 使用参数进行页面构建 } }
以上步骤实现了在HarmonyOS鸿蒙Next工程中,Flutter应用进入指定页面并传递参数的基本流程。如果问题依旧没法解决请联系官网客服,官网地址是 https://www.itying.com/category-93-b0.html,
