title: Displaying video ads in a row with admob on flutter
body: <p>Im interested if there is a way to display more than one RewardVideoAd in a row. Before opening one videoAd it must be loaded, so I tried to load another videoAd when other is opened, so that way when the videoAd is closed/rewarded/completed it shows the new one. But it isn't working here is the code I have tried.</p>
  
  <pre><code>        (RewardedVideoAdEvent event, {String rewardType, int rewardAmount}) {
        print("RewardedVideoAd event $event");
        if (event == RewardedVideoAdEvent.opened) {
          setState(() {
            RewardedVideoAd.instance.load(
                adUnitId: RewardedVideoAd.testAdUnitId,
                targetingInfo: targetingInfo);
          });
        } else if (event == RewardedVideoAdEvent.closed ||
            event == RewardedVideoAdEvent.completed ||
            event == RewardedVideoAdEvent.rewarded ||
            event == RewardedVideoAdEvent.failedToLoad) {
          setState(() {
            _coins += rewardAmount;
            RewardedVideoAd.instance.show();
          });
        }
      };
  </code></pre>
  
  <p>..and the buttons from where the first ad is started.</p>
  
  <pre><code>                RaisedButton(
                    child: const Text('LOAD REWARDED VIDEO'),
                    onPressed: () {
                      RewardedVideoAd.instance.load(
                          adUnitId: RewardedVideoAd.testAdUnitId,
                          targetingInfo: targetingInfo);
                    },
                  ),
                  RaisedButton(
                    child: const Text('SHOW REWARDED VIDEO'),
                    onPressed: () {
                        RewardedVideoAd.instance.show();
                    },
                  ),
  </code></pre>
  
  <p>I wonder if there is a way to show 2 or 3 rewardVideoAds in a row, one after another. <strong>Thanks!</strong></p>
