Too many messages - The webview is destroyed. Ignoring action

Question

After the admob was added to the project and used I constantly get such messages in console when nothing happens on screen adn the app gets too slow.

I/Ads ( 3001): This request is sent from a test device.

I used it in a Stateless widget this way:

 @override
 Widget build(BuildContext context) {
    BannerAd _currentBannerAd = BannerAd(
      adUnitId: AdManager.bannerAdUnitId,
      size: AdSize.banner,
    );
    
    void _loadBannerAd() {
      _currentBannerAd
        ..load()
        ..show(anchorType: AnchorType.bottom);
    }
    
    _loadBannerAd();

    return FutureBuilder<List<String>>(...

As mentioned in the docs, dispose() should be called when access to the ad is no longer needed. The cause for the app slow down is likely because of the ad being initialized multiple times without being disposed.
