Flutter广告管理插件one_admax_flutter的使用

one_admax_flutter 是一个用于在 Flutter 应用中集成和管理广告的插件。它支持多种广告格式，如横幅广告、插页广告、激励视频广告等。以下是如何使用 one_admax_flutter 插件的基本步骤：

1. 添加依赖

首先，在 pubspec.yaml 文件中添加 one_admax_flutter 插件的依赖：

dependencies:
  flutter:
    sdk: flutter
  one_admax_flutter: ^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 应用启动时，初始化 one_admax_flutter 插件。通常可以在 main.dart 文件中的 main 函数中进行初始化：

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

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  
  // 初始化 OneAdMax
  await OneAdMax.init(
    appKey: 'YOUR_APP_KEY', // 替换为你的 App Key
  );

  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

3. 加载和显示广告

one_admax_flutter 支持多种广告类型，以下是加载和显示横幅广告和插页广告的示例。

横幅广告

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

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

class _BannerAdExampleState extends State<BannerAdExample> {
  BannerAd? _bannerAd;

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

  void _loadBannerAd() {
    _bannerAd = BannerAd(
      adUnitId: 'YOUR_BANNER_AD_UNIT_ID', // 替换为你的 Banner Ad Unit ID
      size: BannerSize.BANNER,
      listener: BannerAdListener(
        onAdLoaded: (ad) {
          print('Banner Ad loaded');
        },
        onAdFailedToLoad: (ad, error) {
          print('Banner Ad failed to load: $error');
        },
        onAdClicked: (ad) {
          print('Banner Ad clicked');
        },
      ),
    );
    _bannerAd?.load();
  }

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

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

插页广告

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

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

class _InterstitialAdExampleState extends State<InterstitialAdExample> {
  InterstitialAd? _interstitialAd;

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

  void _loadInterstitialAd() {
    InterstitialAd.load(
      adUnitId: 'YOUR_INTERSTITIAL_AD_UNIT_ID', // 替换为你的 Interstitial Ad Unit ID
      request: AdRequest(),
      adLoadCallback: InterstitialAdLoadCallback(
        onAdLoaded: (ad) {
          setState(() {
            _interstitialAd = ad;
          });
          print('Interstitial Ad loaded');
        },
        onAdFailedToLoad: (error) {
          print('Interstitial Ad failed to load: $error');
        },
      ),
    );
  }

  void _showInterstitialAd() {
    if (_interstitialAd != null) {
      _interstitialAd?.show();
    } else {
      print('Interstitial Ad not loaded yet');
    }
  }

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

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