导航至下一页时如何隐藏横幅广告? [英] How to hide banner ad when navigating to next page in flutter?

问题描述

我正在使用 firebase_admob 插件在Flutter应用中设置广告.我尝试了横幅广告，但效果很好，但是当我导航到另一个页面时，它仍然保持在原位置.我希望该广告在导航到另一页时应隐藏.

I am setting ads in flutter app using firebase_admob plugin. I tried banner ad and it is working fine but, when i navigate to another page it still remains at its position. I want that ad should hide when navigating to another page.

代码段如下.

BannerAd myBanner = BannerAd(
  // Replace the testAdUnitId with an ad unit id from the AdMob dash.
  // https://developers.google.com/admob/android/test-ads
  // https://developers.google.com/admob/ios/test-ads
  adUnitId: BannerAd.testAdUnitId,
  size: AdSize.smartBanner,
  targetingInfo: targetingInfo,
  listener: (MobileAdEvent event) {
    print("BannerAd event is $event");
  },
);
myBanner
  // typically this happens well before the ad is shown
  ..load()
  ..show(
    // Positions the banner ad 60 pixels from the bottom of the screen
    anchorOffset: 60.0,
    // Banner Position
    anchorType: AnchorType.bottom,
  );

当页面被破坏时，将调用

推荐答案

dispose().因此，您可以在那里发布横幅广告.

dispose() will be called when a page is destroyed. So you can distroy banner ad there.

  @override
  void dispose() {

    myBanner.dispose();

    super.dispose();
  }
