如何在flutter中加载并显示adx锚定的自适应广告

这很容易

试试这个来加载谷歌广告管理器广告.

1. Use google_mobile_ads: ^3.0.0个

对于加载广告

AdManagerBannerAd? _anchoredAdaptiveAd;
bool _isLoaded = false;

Future<void> _loadAd() async {
    final AnchoredAdaptiveBannerAdSize? size =
        await AdSize.getCurrentOrientationAnchoredAdaptiveBannerAdSize(
            MediaQuery.of(context).size.width.truncate());

    if (size == null) {
      return;
    }

    _anchoredAdaptiveAd = AdManagerBannerAd(
      adUnitId: // your adID,
      request: const AdManagerAdRequest(),
      listener: AdManagerBannerAdListener(
        onAdLoaded: (Ad ad) {
          setState(() {
            _anchoredAdaptiveAd = ad as AdManagerBannerAd?;
            _isLoaded = true;
          });
        },
        onAdFailedToLoad: (Ad ad, LoadAdError error) {
          ad.dispose();
        },
      ),
      sizes: [size],
    );
    return _anchoredAdaptiveAd!.load();
  }

用于显示广告

SafeArea(
              bottom: true,
              child: Center(
                child: _anchoredAdaptiveAd != null && _isLoaded
                    ? SizedBox(
                        width: _anchoredAdaptiveAd!.sizes[0].width.toDouble(),
                        height: _anchoredAdaptiveAd!.sizes[0].height.toDouble(),
                        child: AdWidget(ad: _anchoredAdaptiveAd!),
                      )
                    : Container(),
              ),
            ),

对于处置广告

  @override
  void dispose() {
    super.dispose();
    _anchoredAdaptiveAd?.dispose();
    rewardedAd?.dispose();
  }
