方法 \'AdListener\' 没有为类型 \'NavigationCounter\' 定义

Question

更新 google_mobile_ads 13.0 后出现错误。未为类型“NavigationCounter”定义方法“AdListener”。

    listener = AdListener(
  // Called when an ad is successfully received.
  onAdLoaded: (Ad ad) {
    //appLockService.disable();
    googleLoad = true;
  },
  // Called when an ad request failed.
  onAdFailedToLoad: (Ad ad, LoadAdError error) {
    print('Ad failed to load: $error');
    //googleLoad = false;
    myInterstitial.dispose();
    //appLockService.unlockScreen();
    //myInterstitial.load();
  },
  // 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) async {
    await isPurchasedFunc();
    print('Ad closed.');
    _adCount++;
    googleLoad = false;
    myInterstitial.dispose();

    if (_adCount == 1) {
      print("isPurchased: $isPurchased & openCount:$openCount");
      if ((isPurchased == null || isPurchased == false) &&
          (openCount == 2 || openCount == 4)) {
        inAppDialog(context);
      }
    }
 
  },
  // Called when an ad is in the process of leaving the application.
  onApplicationExit: (Ad ad) => print('Left application.'),
);

卡在听众 =广告监听器()

替换为BannerAdListener();

BannerAd(
   size: AdSize.mediumRectangle,
   adUnitId: AdHelper.bannerAdUnitId,
   request: AdRequest(),
   listener: BannerAdListener(
     onAdLoaded: (_) {
       setState(() {
         _isInlineBannerAdLoaded = true;
       });
     },
     onAdFailedToLoad: (ad, error) {
       ad.dispose();
     },
   ),
 )
