firebase - Flutter firebase-admob 检查奖励视频是否正在加载

Question

使用 flutter 和这个插件( https://pub.dartlang.org/packages/firebase_admob )，

如何检查奖励视频是否已加载？

我收到此异常:

PlatformException(ad_not_loaded, show failed for rewarded video, no ad was loaded, null)

但我无法捕捉它。

谢谢你。

您需要使用 await 关键字

 void showRewardedAd() async {
    try {
      await RewardedVideoAd.instance.load(
          adUnitId: RewardedVideoAd.testAdUnitId, targetingInfo: targetingInfo);

      await RewardedVideoAd.instance.show();
    } on PlatformException catch (e) {
      print(e.message);
    }
  }

并在您的监听器方法上添加以下行

 if (event == RewardedVideoAdEvent.loaded) {
        setState(() {
         isRewardADLoaded = true;
        });
      }
