Loading an Interstitial Ad
The following code shows you how to attach listeners and load the first interstitial:
final String _interstitial_ad_unit_ID = Platform.isAndroid ? "android_inter_ad_unit_ID" : "ios_inter_ad_unit_ID"; var _interstitialRetryAttempt = 0; void initializeInterstitialAds() { AppLovinMAX.setInterstitialListener(InterstitialListener( onAdLoadedCallback: (ad) { // Interstitial ad is ready to show. AppLovinMAX.isInterstitialReady(_interstitial_ad_unit_ID) now returns 'true'. print('Interstitial ad loaded from ' + ad.networkName); // Reset retry attempt _interstitialRetryAttempt = 0; }, onAdLoadFailedCallback: (adUnitId, error) { // Interstitial ad failed to load. // AppLovin recommends that you retry with exponentially higher delays up to a maximum delay (in this case 64 seconds). _interstitialRetryAttempt = _interstitialRetryAttempt + 1; int retryDelay = pow(2, min(6, _interstitialRetryAttempt)).toInt(); print('Interstitial ad failed to load with code ' + error.code.toString() + ' - retrying in ' + retryDelay.toString() + 's'); Future.delayed(Duration(milliseconds: retryDelay * 1000), () { AppLovinMAX.loadInterstitial(_interstitial_ad_unit_ID); }); }, onAdDisplayedCallback: (ad) { ⋮ }, onAdDisplayFailedCallback: (ad, error) { ⋮ }, onAdClickedCallback: (ad) { ⋮ }, onAdHiddenCallback: (ad) { ⋮ }, )); // Load the first interstitial. AppLovinMAX.loadInterstitial(_interstitial_ad_unit_ID); }
Showing an Interstitial Ad
To show an interstitial ad, call showInterstitial()
:
bool isReady = (await AppLovinMAX.isInterstitialReady(_interstitial_ad_unit_ID))!; if (isReady) { AppLovinMAX.showInterstitial(_interstitial_ad_unit_ID); }
