aorun_ad 是一个用于 Flutter 应用的广告集成插件，它可以帮助开发者在应用中轻松集成广告，如横幅广告、插页式广告、激励视频广告等。以下是如何使用 aorun_ad 插件的基本步骤：

1. 添加依赖

首先，你需要在 pubspec.yaml 文件中添加 aorun_ad 插件的依赖。

dependencies:
  flutter:
    sdk: flutter
  aorun_ad: ^1.0.0  # 请使用最新版本

然后运行 flutter pub get 来获取依赖。

2. 初始化插件

在你的应用启动时，你需要初始化 aorun_ad 插件。通常可以在 main.dart 文件中的 main 函数中进行初始化。

import 'package:aorun_ad/aorun_ad.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  
  // 初始化 aorun_ad
  await AorunAd.initialize(
    appId: 'your_app_id',  // 替换为你的应用ID
  );

  runApp(MyApp());
}

3. 显示横幅广告

横幅广告通常显示在屏幕的顶部或底部。你可以使用 BannerAd 组件来显示横幅广告。

import 'package:aorun_ad/aorun_ad.dart';

class MyHomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter Ad Example'),
      ),
      body: Column(
        children: [
          Expanded(
            child: Center(
              child: Text('Hello, World!'),
            ),
          ),
          BannerAd(
            adUnitId: 'your_banner_ad_unit_id',  // 替换为你的横幅广告单元ID
            size: AdSize.banner,
            listener: (AdEvent event) {
              // 处理广告事件
            },
          ),
        ],
      ),
    );
  }
}

4. 显示插页式广告

插页式广告通常在应用的自然过渡点显示，例如在页面切换时。你可以使用 InterstitialAd 来显示插页式广告。

import 'package:aorun_ad/aorun_ad.dart';

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  InterstitialAd _interstitialAd;

  @override
  void initState() {
    super.initState();
    _loadInterstitialAd();
  }

  void _loadInterstitialAd() {
    InterstitialAd.load(
      adUnitId: 'your_interstitial_ad_unit_id',  // 替换为你的插页式广告单元ID
      request: AdRequest(),
      adLoadCallback: InterstitialAdLoadCallback(
        onAdLoaded: (InterstitialAd ad) {
          setState(() {
            _interstitialAd = ad;
          });
        },
        onAdFailedToLoad: (LoadAdError error) {
          print('InterstitialAd failed to load: $error');
        },
      ),
    );
  }

  void _showInterstitialAd() {
    if (_interstitialAd != null) {
      _interstitialAd.show();
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter Ad Example'),
      ),
      body: Center(
        child: ElevatedButton(
          onPressed: _showInterstitialAd,
          child: Text('Show Interstitial Ad'),
        ),
      ),
    );
  }

  @override
  void dispose() {
    _interstitialAd?.dispose();
    super.dispose();
  }
}

5. 显示激励视频广告

激励视频广告通常用于奖励用户观看广告。你可以使用 RewardedAd 来显示激励视频广告。

import 'package:aorun_ad/aorun_ad.dart';

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  RewardedAd _rewardedAd;

  @override
  void initState() {
    super.initState();
    _loadRewardedAd();
  }

  void _loadRewardedAd() {
    RewardedAd.load(
      adUnitId: 'your_rewarded_ad_unit_id',  // 替换为你的激励视频广告单元ID
      request: AdRequest(),
      rewardedAdLoadCallback: RewardedAdLoadCallback(
        onAdLoaded: (RewardedAd ad) {
          setState(() {
            _rewardedAd = ad;
          });
        },
        onAdFailedToLoad: (LoadAdError error) {
          print('RewardedAd failed to load: $error');
        },
      ),
    );
  }

  void _showRewardedAd() {
    if (_rewardedAd != null) {
      _rewardedAd.show(
        onUserEarnedReward: (RewardedAd ad, RewardItem reward) {
          // 用户获得奖励
          print('User earned reward: ${reward.amount} ${reward.type}');
        },
      );
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter Ad Example'),
      ),
      body: Center(
        child: ElevatedButton(
          onPressed: _showRewardedAd,
          child: Text('Show Rewarded Ad'),
        ),
      ),
    );
  }

  @override
  void dispose() {
    _rewardedAd?.dispose();
    super.dispose();
  }
}

6. 处理广告事件

你可以在广告的 listener 回调中处理广告事件，例如广告加载成功、失败、点击等。

BannerAd(
  adUnitId: 'your_banner_ad_unit_id',
  size: AdSize.banner,
  listener: (AdEvent event) {
    switch (event) {
      case AdEvent.loaded:
        print('Ad loaded.');
        break;
      case AdEvent.failedToLoad:
        print('Ad failed to load.');
        break;
      case AdEvent.opened:
        print('Ad opened.');
        break;
      case AdEvent.clicked:
        print('Ad clicked.');
        break;
      case AdEvent.closed:
        print('Ad closed.');
        break;
    }
  },
);
