找不到带有以下内容的广告。原生广告 Flutter google_mobile_ads

Question

原生广告显示错误。我使用来自 google.
的测试广告 ID “此广告可能尚未加载或已被处理。具有以下 ID 的广告不能 found:1”

谁能帮帮我？

编辑 #1 我的代码原生广告有不同的示例代码吗？我使用 google_mobile_ads: ^0.13.2

...

   class _GameState extends State<Game> {
  static const AdRequest targetingInfo = AdRequest(
  );

  static const int maxFailedLoadAttempts = 3;



  static const _adUnitIDNative = "ca-app-pub-3940256099942544/2247696110";

  late StreamSubscription _subscription;
  bool? _deutsch;

  final NativeAd myNative = NativeAd(
    adUnitId: _adUnitIDNative,
    factoryId: 'listTile',
    request: AdRequest(),
    listener: NativeAdListener(),
  );

  final NativeAdListener listener = NativeAdListener(
    // Called when an ad is successfully received.
    onAdLoaded: (Ad ad) => print('Ad loaded.'),
    // Called when an ad request failed.
    onAdFailedToLoad: (Ad ad, LoadAdError error) {
      // Dispose the ad here to free resources.
      ad.dispose();
      print('NativeAd failed to load: $error');
    },
    // Called when an ad opens an overlay that covers the screen.
    onAdOpened: (Ad ad) => print('Ad opened.'),
    // Called when an ad removes an overlay that covers the screen.
    onAdClosed: (Ad ad) => print('Ad closed.'),
    // Called when an impression occurs on the ad.
    onAdImpression: (Ad ad) => print('Ad impression.'),
    // Called when a click is recorded for a NativeAd.
    onNativeAdClicked: (NativeAd ad) => print('Ad clicked.'),
  );

  get adContainer => null;

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

    _createInterstitialAd();
   
    myNative.load();
  }

...

Container(
                      alignment: Alignment.center,
                      child: AdWidget(ad: myNative),
                      padding: EdgeInsets.all(10),
                      margin: EdgeInsets.only(bottom: 20.0),
                      height: 70,                      
                    ),

谢谢

您的 AdWidget 在广告加载完成之前正在构建；你需要实现三件事：

布尔标志：表示广告已完成加载；
侦听事件：加载广告时，将标志设置为 true 并触发重建；和
触发小部件：如果为真，则构建广告小部件。

  // 1. Create bool
  bool isAdLoaded = false;

  // 2. Add listener event
  final NativeAdListener listener = NativeAdListener(
    // Called when an ad is successfully received.
    onAdLoaded: (Ad ad) => {
      setState(() {
        isAdLoaded = true;
      });

  ...

  // 3. Wrap the AdWidget inside a switch
  isAdLoaded ? Container(
    alignment: Alignment.center,
    child: AdWidget(ad: myNative),
    padding: EdgeInsets.all(10),
    margin: EdgeInsets.only(bottom: 20.0),
    height: 70,                      
  ) : CircularProgressIndicator(),
