【问题描述】：
我已经测试了bannerAds，它工作正常，但是当我尝试加载插页式广告时，应用程序崩溃了。
MinSdkVersion 29 我尝试在 initState 和 build 方法中分别加载广告。
横幅广告运行正常。
InterstitialAd loadInterstitialAd() {
return InterstitialAd(
adUnitId: "ca-app-pub-3940256099942544/1033173712",
listener: AdListener(onAdLoaded: (_) {
setState(() {
_isAdLoaded = true;
});
}, onAdFailedToLoad: (_ad, error) {
_ad.dispose();
print("Ad Exited with error $error");
}, onAdClosed: (_ad) {
Navigator.pop(context);
_ad.dispose();
}),
request: AdRequest());
}
@override
Widget build(BuildContext context) {
InterstitialAd _ad = loadInterstitialAd();
_ad.load();
return Scaffold(
body: Center(
child: MaterialButton(
onPressed: () {},
color: Colors.red,
)
),
);
}
错误日志是这样的
