示例代码

以下是一个完整的示例代码，展示了如何在 Flutter 应用中使用 flutter_whip 插件。

import 'dart:core';

import 'package:flutter/material.dart';
import 'package:flutter_webrtc/flutter_webrtc.dart';

import 'route_item.dart';
import 'pages/publish_sample.dart';
import 'pages/subscribe_sample.dart';

void main() {
  // 如果不是在 Web 环境中运行，则初始化 Flutter 绑定
  if (!WebRTC.platformIsWeb) {
    WidgetsFlutterBinding.ensureInitialized();
  }
  runApp(MyApp());
}

// 定义 MyApp 类，继承自 StatefulWidget
class MyApp extends StatefulWidget {
  [@override](/user/override)
  _MyAppState createState() => _MyAppState();
}

// 定义 _MyAppState 类，继承自 State<MyApp>
class _MyAppState extends State<MyApp> {
  // 定义一个列表来存储路由项
  late List<RouteItem> items;

  // 初始化路由项
  void initState() {
    super.initState();
    _initItems();
  }

  // 构建行
  ListBody _buildRow(context, item) {
    return ListBody(children: <Widget>[
      ListTile(
        title: Text(item.title), // 显示标题
        onTap: () => item.push(context), // 处理点击事件
        trailing: Icon(Icons.arrow_right), // 添加箭头图标
      ),
      Divider() // 添加分隔符
    ]);
  }

  // 构建应用主界面
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
          appBar: AppBar(
            title: Text('Flutter WHIP example'), // 设置标题
          ),
          body: ListView.builder(
              shrinkWrap: true,
              padding: const EdgeInsets.all(0.0),
              itemCount: items.length,
              itemBuilder: (context, i) {
                return _buildRow(context, items[i]); // 构建列表项
              })),
    );
  }

  // 初始化路由项
  void _initItems() {
    items = <RouteItem>[
      RouteItem(
          title: 'Publish Sample', // 发布示例
          push: (BuildContext context) {
            Navigator.push(
                context,
                MaterialPageRoute(
                    builder: (BuildContext context) => WhipPublishSample())); // 导航到发布页面
          }),
      RouteItem(
          title: 'Subscribe Sample', // 订阅示例
          push: (BuildContext context) {
            Navigator.push(
                context,
                MaterialPageRoute(
                    builder: (BuildContext context) => WhipSubscribeSample())); // 导航到订阅页面
          }),
    ];
  }
}

route_item.dart 文件

class RouteItem {
  final String title;
  final Function(BuildContext) push;

  RouteItem({required this.title, required this.push});
}

publish_sample.dart 文件

import 'package:flutter/material.dart';
import 'package:flutter_webrtc/flutter_webrtc.dart';

class WhipPublishSample extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Publish Sample'),
      ),
      body: Center(
        child: Text('Publish Sample Page'),
      ),
    );
  }
}

subscribe_sample.dart 文件

import 'package:flutter/material.dart';
import 'package:flutter_webrtc/flutter_webrtc.dart';

class WhipSubscribeSample extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Subscribe Sample'),
      ),
      body: Center(
        child: Text('Subscribe Sample Page'),
      ),
    );
  }
