插屏广告

1. 插屏广告

插屏广告SDK的导入：

import 'package:anythink_sdk/at_index.dart';

1.1 加载插屏广告

使用以下代码加载Interstitial广告

loadInterstitialAd() async {
    await ATinterstitialManager
        .loadInterstitialAd(placementID: 'you placementId', extraMap: {});
  }

只针对Sigmob平台，Sigmob的激励视频广告源当做插屏使用（可选，注意：开启后Taku后台Sigmob插屏广告源需配置成Sigmob的激励视频参数）

loadInterstitialAd() async {
    await ATinterstitialManager
        .loadInterstitialAd(placementID: 'you placementId', extraMap: {
            ATinterstitialManager.UseRewardedVideoAsInterstitialKey(): true
        });
  }

1.2 判断是否有广告缓存以及获取广告状态

使用以下代码判断是否有广告缓存：

 _hasInterAdReady() async {
    await ATinterstitialManager
        .hasInterstitialAdReady(
      placementID: 'you placementId',
    )
        .then((value) {
      print('flutter插屏广告视频缓存$value');
    });
  }

使用以下代码获取广告状态（返回值类型为Map） key-value如下：

1、isLoading：是否正在加载

2、isReady：是否有广告缓存

3、adInfo：当前优先级最高的广告缓存信息

 _checkInterAdStatus() async {
    await ATinterstitialManager
        .CheckInterstitialLoadStatus(
      placementID: 'b5bacad80a0fb1',
    )
        .then((value) {
      print('flutter插屏广告广告视频状态$value');
    });
  }

获取当前广告位下所有可用广告的信息

getInterstitialValidAds() async {
    await ATinterstitialManager
        .getInterstitialValidAds(
      placementID: Configuration.interstitialPlacementID,
    )
        .then((value) {
      print('flutter插屏广告广告视频状态$value');
    });
  }

1.3 展示插屏广告

插屏广告只要调用展示api并传递展示广告位ID

_showInterAd() async {
    await ATinterstitialManager
        .showInterstitialAd(
      placementID: 'you placementId',
    );
  }

当使用场景功能时，通过此api展示广告,参数为:广告位ID+场景ID(场景ID可通过Taku后台创建）

showSceneInterstitialAd() async {
    await ATinterstitialManager
        .showSceneInterstitialAd(
      placementID: 'you placementId',
      sceneID: 'you sceneID',
    );
  }

1.4 实现插屏的监听器

ATInterstitialResponse属性介绍:

InterstitialStatus: 插屏广告状态

placementID: placementID

requestMessage: 请求信息（错误信息）

extraMap: 回调信息

isDeeplinkSuccess: isDeeplinkSuccess

有关插屏广告事件的通知示例如下:

_interListen() {

    ATListenerManager.interstitialEventHandler.listen((value) {

      switch (value.interstatus) {
        //广告加载失败
        case InterstitialStatus.interstitialAdFailToLoadAD:
          print("flutter interstitialAdFailToLoadAD ---- placementID: ${value.placementID} ---- errStr:${value.requestMessage}");
          break;
        //广告加载成功  
        case InterstitialStatus.interstitialAdDidFinishLoading:
          print("flutter interstitialAdDidFinishLoading ---- placementID: ${value.placementID}");
          break;
        //广告视频开始播放，部分平台有此回调  
        case InterstitialStatus.interstitialAdDidStartPlaying:
          print("flutter interstitialAdDidStartPlaying ---- placementID: ${value.placementID} ---- extra:${value.extraMap}");
          break;
        //广告视频播放结束，部分广告平台有此回调  
        case InterstitialStatus.interstitialAdDidEndPlaying:
          print("flutter interstitialAdDidEndPlaying ---- placementID: ${value.placementID} ---- extra:${value.extraMap}");
          break;
        //广告视频播放失败，部分广告平台有此回调  
        case InterstitialStatus.interstitialDidFailToPlayVideo:
          print("flutter interstitialDidFailToPlayVideo ---- placementID: ${value.placementID} ---- errStr:${value.requestMessage}");
          break;
        //广告展示成功  
        case InterstitialStatus.interstitialDidShowSucceed:
          print("flutter interstitialDidShowSucceed ---- placementID: ${value.placementID} ---- extra:${value.extraMap}");
          break;
        //广告展示失败  
        case InterstitialStatus.interstitialFailedToShow:
          print("flutter interstitialFailedToShow ---- placementID: ${value.placementID} ---- errStr:${value.requestMessage}");
          break;
        //广告被点击  
        case InterstitialStatus.interstitialAdDidClick:
          print("flutter interstitialAdDidClick ---- placementID: ${value.placementID} ---- extra:${value.extraMap}");
          break;
        //Deeplink  
        case InterstitialStatus.interstitialAdDidDeepLink:
          print("flutter interstitialAdDidDeepLink ---- placementID: ${value.placementID} ---- extra:${value.extraMap}");
          break;
        //广告被关闭  
        case InterstitialStatus.interstitialAdDidClose:
          print("flutter interstitialAdDidClose ---- placementID: ${value.placementID} ---- extra:${value.extraMap}");
          break;

        case InterstitialStatus.interstitialUnknown:
          print("flutter interstitialUnknown");
          break;
      }
    });
}
