Question

我试图让横幅广告出现在我的主屏幕上，但它不会出现。我使用了 firebase_admob 0.11.0+1 包。我创建了 firebase 和 google admob 帐户，将它们链接在一起并获取了 appId 和横幅 ID，并添加了代码，但它不起作用。

我还在包中给出的清单文件中添加了 appID

const String testDevice = 'YOUR_DEVICE_ID';
const testAppId = "ca-app-pub-6340236221743124~6413606161";
const testAdUnitId = "ca-app-pub-6340236221743124~6413606161";

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  runApp(MyApp());
}

class MyApp extends StatelessWidget {


  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      theme: ThemeData.light(),
      title: "Start of the app",
      debugShowCheckedModeBanner: false,
      home: MyHomePage(),
    );
  }
}

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

class _MyHomePageState extends State<MyHomePage> {

  static const MobileAdTargetingInfo targetingInfo = MobileAdTargetingInfo(
    testDevices: testDevice != null ? <String>[testDevice] : null,
    keywords: <String>['foo', 'bar'],
    contentUrl: 'http://example.com',
    childDirected: true,
    nonPersonalizedAds: true,
  );

  BannerAd _bannerAd;

  BannerAd createBannerAd() {
    return BannerAd(
      adUnitId: BannerAd.testAdUnitId,
      size: AdSize.banner,
      targetingInfo: targetingInfo,
      listener: (MobileAdEvent event) {
        print("BannerAd event $event");
      },
    );
  }

  @override
  void initState() {
    super.initState();
    FirebaseAdMob.instance.initialize(appId: FirebaseAdMob.testAppId);
    _bannerAd = createBannerAd()..load();
  }

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('AdMob Plugin example app'),
        ),
        body: SingleChildScrollView(
          child: Center(
            child: Column(
              crossAxisAlignment: CrossAxisAlignment.center,
              mainAxisSize: MainAxisSize.min,
              children: <Widget>[

                RaisedButton(
                    child: const Text('SHOW BANNER WITH OFFSET'),
                    onPressed: () {
                      _bannerAd ??= createBannerAd();
                      _bannerAd
                        ..load()
                        ..show(horizontalCenterOffset: -50, anchorOffset: 100);
                    }),]),),),),);}}

嗯，在我看来，你的代码没有问题。构建错误表明您的 build.gradle abd AndroidX 存在问题。

你能用你的 build.gradle 回复我或者把它添加到你的原始帖子中吗？

顺便说一句- 请看一下这个 github 问题 - https://github.com/FirebaseExtended/flutterfire/issues/2511
