tapsell_mediation_fyber 是一个用于 Flutter 的广告中介插件，它允许开发者在应用中集成来自 Tapsell 和 Fyber 的广告。通过使用这个插件，开发者可以轻松地在应用中展示横幅广告、插页式广告、激励视频广告等。

以下是如何使用 tapsell_mediation_fyber 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 tapsell_mediation_fyber 插件的依赖。

dependencies:
  flutter:
    sdk: flutter
  tapsell_mediation_fyber: ^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 Flutter 应用中初始化插件。通常，你可以在 main.dart 文件中进行初始化。

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

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  
  // 初始化 Tapsell Mediation Fyber 插件
  await TapsellMediationFyber.initialize(
    tapsellAppKey: 'YOUR_TAPSELL_APP_KEY',
    fyberAppId: 'YOUR_FYBER_APP_ID',
    fyberSecurityToken: 'YOUR_FYBER_SECURITY_TOKEN',
  );

  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Tapsell Fyber Demo',
      home: HomeScreen(),
    );
  }
}

3. 展示广告

你可以使用插件提供的 API 来展示不同类型的广告。以下是一些常见的广告类型示例：

横幅广告

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

class BannerAdScreen extends StatefulWidget {
  [@override](/user/override)
  _BannerAdScreenState createState() => _BannerAdScreenState();
}

class _BannerAdScreenState extends State<BannerAdScreen> {
  late BannerAd _bannerAd;

  [@override](/user/override)
  void initState() {
    super.initState();
    _bannerAd = BannerAd(
      adUnitId: 'YOUR_BANNER_AD_UNIT_ID',
      size: AdSize.banner,
      listener: BannerAdListener(
        onAdLoaded: (Ad ad) => print('Ad loaded.'),
        onAdFailedToLoad: (Ad ad, LoadAdError error) {
          ad.dispose();
          print('Ad failed to load: $error');
        },
        onAdOpened: (Ad ad) => print('Ad opened.'),
        onAdClosed: (Ad ad) => print('Ad closed.'),
      ),
    );

    _bannerAd.load();
  }

  [@override](/user/override)
  void dispose() {
    _bannerAd.dispose();
    super.dispose();
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Banner Ad'),
      ),
      body: Center(
        child: AdWidget(ad: _bannerAd),
      ),
    );
  }
}

插页式广告

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

class InterstitialAdScreen extends StatefulWidget {
  [@override](/user/override)
  _InterstitialAdScreenState createState() => _InterstitialAdScreenState();
}

class _InterstitialAdScreenState extends State<InterstitialAdScreen> {
  InterstitialAd? _interstitialAd;

  [@override](/user/override)
  void initState() {
    super.initState();
    _loadInterstitialAd();
  }

  void _loadInterstitialAd() {
    InterstitialAd.load(
      adUnitId: 'YOUR_INTERSTITIAL_AD_UNIT_ID',
      request: AdRequest(),
      adLoadCallback: InterstitialAdLoadCallback(
        onAdLoaded: (InterstitialAd ad) {
          _interstitialAd = ad;
          _interstitialAd?.setFullScreenContentCallback(
            FullScreenContentCallback(
              onAdDismissedFullScreenContent: (InterstitialAd ad) {
                ad.dispose();
                _loadInterstitialAd();
              },
              onAdFailedToShowFullScreenContent: (InterstitialAd ad, AdError error) {
                ad.dispose();
                _loadInterstitialAd();
              },
            ),
          );
        },
        onAdFailedToLoad: (LoadAdError error) {
          print('InterstitialAd failed to load: $error');
        },
      ),
    );
  }

  void _showInterstitialAd() {
    if (_interstitialAd != null) {
      _interstitialAd?.show();
    } else {
      print('InterstitialAd is not ready yet.');
    }
  }

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

激励视频广告

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

class RewardedAdScreen extends StatefulWidget {
  [@override](/user/override)
  _RewardedAdScreenState createState() => _RewardedAdScreenState();
}

class _RewardedAdScreenState extends State<RewardedAdScreen> {
  RewardedAd? _rewardedAd;

  [@override](/user/override)
  void initState() {
    super.initState();
    _loadRewardedAd();
  }

  void _loadRewardedAd() {
    RewardedAd.load(
      adUnitId: 'YOUR_REWARDED_AD_UNIT_ID',
      request: AdRequest(),
      rewardedAdLoadCallback: RewardedAdLoadCallback(
        onAdLoaded: (RewardedAd ad) {
          _rewardedAd = ad;
          _rewardedAd?.setFullScreenContentCallback(
            FullScreenContentCallback(
              onAdDismissedFullScreenContent: (RewardedAd ad) {
                ad.dispose();
                _loadRewardedAd();
              },
              onAdFailedToShowFullScreenContent: (RewardedAd ad, AdError error) {
                ad.dispose();
                _loadRewardedAd();
              },
            ),
          );
        },
        onAdFailedToLoad: (LoadAdError error) {
          print('RewardedAd failed to load: $error');
        },
      ),
    );
  }

  void _showRewardedAd() {
    if (_rewardedAd != null) {
      _rewardedAd?.show(
        onUserEarnedReward: (RewardedAd ad, RewardItem reward) {
          print('User earned reward: ${reward.amount} ${reward.type}');
        },
      );
    } else {
      print('RewardedAd is not ready yet.');
    }
  }

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