flutter - 消息太多 - Web View 被破坏。忽略 Action

Question

将 admob 添加到项目并使用后，当屏幕上没有任何反应且应用程序变得太慢时，我经常在控制台中收到此类消息。

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

W/Ads ( 3001): #004 The webview is destroyed. Ignoring action.

I/chatty ( 3001): uid=10080(com.github.testapp) identical 1 line

我以这种方式在无状态小部件中使用它:

 @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>>(...

如 docs 中所述, dispose() 应在不再需要访问广告时调用。应用变慢的原因很可能是因为广告被多次初始化而没有被释放。
