admob_flutter包是一个用于在Flutter应用中集成AdMob广告的插件。该插件本身并不直接支持广告中介,但可以通过使用其他插件或自定义代码来实现广告中介功能。
以下是一个示例代码,演示如何使用admob_flutter和flutter_inappwebview插件来实现广告中介功能:
dependencies:
admob_flutter: ^2.0.0
flutter_inappwebview: ^5.3.2
import 'package:admob_flutter/admob_flutter.dart';
import 'package:flutter_inappwebview/flutter_inappwebview.dart';
class AdMobMediation {
static final AdMobMediation _instance = AdMobMediation._internal();
factory AdMobMediation() {
return _instance;
}
AdMobMediation._internal();
String _currentAdUnitId = "";
// 初始化AdMob
void initialize() {
Admob.initialize();
}
// 设置当前广告单元ID
void setCurrentAdUnitId(String adUnitId) {
_currentAdUnitId = adUnitId;
}
// 请求广告
void requestAd() {
if (_currentAdUnitId.isNotEmpty) {
Admob.requestTrackingAuthorization();
AdmobInterstitial interstitialAd = AdmobInterstitial(
adUnitId: _currentAdUnitId,
);
interstitialAd.load();
}
}
// 展示广告
void showAd() {
if (_currentAdUnitId.isNotEmpty) {
AdmobInterstitial interstitialAd = AdmobInterstitial(
adUnitId: _currentAdUnitId,
);
interstitialAd.show();
}
}
}
AdMobMediation adMediation = AdMobMediation();
void main() {
adMediation.initialize();
adMediation.setCurrentAdUnitId("YOUR_AD_UNIT_ID");
adMediation.requestAd();
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'AdMob Mediation Demo',
home: Scaffold(
appBar: AppBar(
title: Text('AdMob Mediation Demo'),
),
body: Center(
child: RaisedButton(
child: Text('Show Ad'),
onPressed: () {
adMediation.showAd();
},
),
),
),
);
}
}
请注意,该示例中使用的是flutter_inappwebview插件来展示广告,您可以根据需要选择其他插件或自定义代码来实现广告中介功能。
