Flutter AWS IVS集成插件flutter_aws_ivs的使用

Flutter AWS IVS 集成插件 flutter_aws_ivs 的使用

flutter_aws_ivs 是一个用于 Amazon Interactive Video Service (IVS) 的 Flutter 平台集成插件（适用于 iOS 和 Android）。Amazon IVS 是一种托管式的直播流解决方案，为移动和网页应用快速搭建直播功能。该服务包括自己的视频播放器 SDK，并且非常适合创建交互式视频体验。

示例代码

import 'dart:io';

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

import 'package:flutter_aws_ivs/flutter_aws_ivs.dart';
import 'package:http_proxy/http_proxy.dart';

// 请替换以下变量值为您的实际 AWS 凭证和区域
const region = ''; // 例如：'us-west-2'
const accessKeyId = ''; // 例如：'AKIAIOSFODNN7EXAMPLE'
const secretAccessKey = ''; // 例如：'wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY'

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  
  // 设置 HTTP 代理
  HttpProxy httpProxy = await HttpProxy.createHttpProxy();
  HttpOverrides.global = httpProxy;
  
  // 初始化 AWS IVS 服务
  AwsIvsService.init(
      accessKeyId: accessKeyId,
      region: region,
      secretAccessKey: secretAccessKey);

  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  [@override](/user/override)
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String _platformVersion = 'Unknown';
  FlutterAwsIvsController? _controller;
  
  [@override](/user/override)
  void initState() {
    super.initState();
    initPlatformState();
  }

  // 异步初始化平台状态
  Future<void> initPlatformState() async {
    if (!mounted) return;

    // 如果需要获取平台版本信息，可以取消注释以下部分
    // try {
    //   String platformVersion = await _flutterAwsIvsPlugin.getPlatformVersion() ?? 'Unknown platform version';
    //   setState(() {
    //     _platformVersion = platformVersion;
    //   });
    // } on PlatformException {
    //   setState(() {
    //     _platformVersion = 'Failed to get platform version.';
    //   });
    // }
  }

  // 当 FlutterAwsIvsView 创建时调用此方法
  void _onFlutterAwsIvsViewCreated(FlutterAwsIvsController controller) {
    _controller = controller;
    controller.initView();
  }
