RewardedVideoAd is not loading in Android

Hi, I am trying load rewarded video ads in Android, but simply nothing happens, no logs are shown at console. I have already implemented successfully NativeAds.

This is my code, I tried execute it in initState() and also at a button click.

void loadAd(){
    print('Try load ad rewarded: ' + videoId;
    FacebookRewardedVideoAd.loadRewardedVideoAd(
      placementId: videoId,
      listener: (result, value) {
        print('Rewarded video: ' + result.toString() + ' => ' + value);
      },
    );
  }

The console:

...
I/flutter (30596): Try load ad rewarded: CCCCCCCCCCCCC_XXXXXXXXXXXXXX
(nothing more)

I already checked the ad id on facebook, it is all right.
