보상형 광고는 사용자에게 상호작용에 대한 대가로 인앱 보상을 제공하는 광고입니다. 이 가이드에서는
AdMob의 보상형 광고를 Flutter 앱에 통합하는 방법을 설명합니다.
항상 테스트 광고로 테스트
앱을 제작하고 테스트할 때는 운영 중인 실제 광고 대신 테스트 광고를 사용하세요. 이렇게 하지 않으면 계정이 정지될 수 있습니다.
테스트 광고를 로드하는 가장 쉬운 방법은 보상형 광고 전용 테스트 광고 단위 ID를 사용하는 것입니다.
Android
ca-app-pub-3940256099942544/5224354917
iOS
ca-app-pub-3940256099942544/1712485313
테스트 광고 단위는 모든 요청에 대해 테스트 광고를 반환하도록 구성되며 코딩, 테스트, 디버깅 중에 앱에서 자유롭게 사용할 수 있습니다.
단, 앱을 게시하기 전에 이 테스트 광고 단위 ID를 자체 광고 단위 ID로 바꿔야
합니다.
광고 로드
다음 예에서는 보상형 광고를 로드합니다.
classRewardedExampleStateextendsState<RewardedExample>{RewardedAd?_rewardedAd;//TODO:replacethistestadunitwithyourownadunit.finaladUnitId=Platform.isAndroid?'ca-app-pub-3940256099942544/5224354917':'ca-app-pub-3940256099942544/1712485313';///Loadsarewardedad.voidloadAd(){RewardedAd.load(adUnitId:adUnitId,request:constAdRequest(),adLoadCallback:RewardedAdLoadCallback(//Calledwhenanadissuccessfullyreceived.onAdLoaded:(ad){debugPrint('$ad loaded.');//Keepareferencetotheadsoyoucanshowitlater._rewardedAd=ad;},//Calledwhenanadrequestfailed.onAdFailedToLoad:(LoadAdErrorerror){debugPrint('RewardedAd failed to load: $error');},));}}
보상형 광고 이벤트
FullScreenContentCallback을 사용하면 광고 게재, 광고 닫기와 같은 수명 주기 이벤트를 수신 대기할 수 있습니다. 이러한
이벤트에 대한 알림을 받으려면 광고를 게재하기 전에
RewardedAd.fullScreenContentCallback을 설정하세요. 이 예에서는 각 메서드를 구현하고 콘솔에 메시지를 기록합니다.
classRewardedExampleStateextendsState<RewardedExample>{RewardedAd?_rewardedAd;//TODO:replacethistestadunitwithyourownadunit.finaladUnitId=Platform.isAndroid?'ca-app-pub-3940256099942544/5224354917':'ca-app-pub-3940256099942544/1712485313';///Loadsarewardedad.voidloadAd(){RewardedAd.load(adUnitId:adUnitId,request:constAdRequest(),adLoadCallback:RewardedAdLoadCallback(//Calledwhenanadissuccessfullyreceived.onAdLoaded:(ad){ad.fullScreenContentCallback=FullScreenContentCallback(//Calledwhentheadshowedthefullscreencontent.onAdShowedFullScreenContent:(ad){},//Calledwhenanimpressionoccursonthead.onAdImpression:(ad){},//Calledwhentheadfailedtoshowfullscreencontent.onAdFailedToShowFullScreenContent:(ad,err){//Disposetheadheretofreeresources.ad.dispose();},//Calledwhentheaddismissedfullscreencontent.onAdDismissedFullScreenContent:(ad){//Disposetheadheretofreeresources.ad.dispose();},//Calledwhenaclickisrecordedforanad.onAdClicked:(ad){});debugPrint('$ad loaded.');//Keepareferencetotheadsoyoucanshowitlater._rewardedAd=ad;},//Calledwhenanadrequestfailed.onAdFailedToLoad:(LoadAdErrorerror){debugPrint('RewardedAd failed to load: $error');},));}}
광고 표시
RewardedAd는 모든 앱 콘텐츠 위에 오버레이로 표시되며 정적으로 배치되므로 Flutter 위젯 트리에 추가할 수 없습니다. show()를 호출하여 광고 게재 시점을 선택할 수 있습니다.
RewardedAd.show()는 사용자가 보상을 획득할 때 호출되는 OnUserEarnedRewardCallback을 사용합니다. 이 이벤트를 구현하고 사용자에게 광고 시청에 대한 보상을
제공해야 합니다.
show()가 호출되면 이 방식으로 게재된 Ad는 프로그래매틱 방식으로 삭제할 수 없으며 사용자가
입력해야 삭제할 수 있습니다. RewardedAd는 한 번만 게재될 수
있습니다. 이후 표시되는 호출에서 onAdFailedToShowFullScreenContent를 트리거합니다.
광고에 대한 액세스가 더 이상 필요하지 않으면 광고를 삭제해야 합니다. dispose()를 호출하기 가장 좋은 시점은 FullScreenContentCallback.onAdDismissedFullScreenContent 및 FullScreenContentCallback.onAdFailedToShowFullScreenContent 콜백이 실행될 때입니다.

This guide shows\nhow to integrate rewarded ads from AdMob into a Flutter app.\n\nAlways test with test ads\n\nWhen building and testing your apps, make sure you use test ads rather than\nlive, production ads. Failure to do so can lead to suspension of your account.\n\nThe easiest way to load test ads is to use our dedicated test ad unit ID for\nrewarded ads: \n\nAndroid \n\n ca-app-pub-3940256099942544/5224354917\n\niOS \n\n ca-app-pub-3940256099942544/1712485313\n\nThe test ad units are configured to return test ads for every request, and\nyou're free to use them in your own apps while coding, testing, and debugging.\nJust make sure you replace them with your own ad unit IDs before publishing your\napp.\n\nLoad an ad\n\nThe following example loads a rewarded ad: \n\n RewardedAd.load(\n adUnitId: \"\u003cvar translate=\"no\"\u003e_adUnitId\u003c/var\u003e\",\n request: const AdRequest(),\n rewardedAdLoadCallback: RewardedAdLoadCallback(\n onAdLoaded: (RewardedAd ad) {\n // Called when an ad is successfully received.\n debugPrint('Ad was loaded.');\n // Keep a reference to the ad so you can show it later.\n _rewardedAd = ad;\n },\n onAdFailedToLoad: (LoadAdError error) {\n // Called when an ad request failed.\n debugPrint('Ad failed to load with error: $error');\n },\n ),\n ); \n https://github.com/googleads/googleads-mobile-flutter/blob/82c58b3202d8b9391e4d3ec39b045032e90cf331/packages/google_mobile_ads/example/lib/snippets/rewarded_ad_snippets.dart#L32-L50\n\nReplace \u003cvar translate=\"no\"\u003e_adUnitId\u003c/var\u003e with your own ad unit ID.\n\nRewarded ad events\n\nThrough the use of `FullScreenContentCallback`, you can listen for lifecycle\nevents, such as when the ad is shown or dismissed. Set\n`RewardedAd.fullScreenContentCallback` before showing the ad to receive\nnotifications for these events. This example implements each method and logs a\nmessage to the console: \n\n ad.fullScreenContentCallback = FullScreenContentCallback(\n onAdShowedFullScreenContent: (ad) {\n // Called when the ad showed the full screen content.\n debugPrint('Ad showed full screen content.');\n },\n onAdFailedToShowFullScreenContent: (ad, err) {\n // Called when the ad failed to show full screen content.\n debugPrint('Ad failed to show full screen content with error: $err');\n // Dispose the ad here to free resources.\n ad.dispose();\n },\n onAdDismissedFullScreenContent: (ad) {\n // Called when the ad dismissed full screen content.\n debugPrint('Ad was dismissed.');\n // Dispose the ad here to free resources.\n ad.dispose();\n },\n onAdImpression: (ad) {\n // Called when an impression occurs on the ad.\n debugPrint('Ad recorded an impression.');\n },\n onAdClicked: (ad) {\n // Called when a click is recorded for an ad.\n debugPrint('Ad was clicked.');\n },\n ); \n https://github.com/googleads/googleads-mobile-flutter/blob/82c58b3202d8b9391e4d3ec39b045032e90cf331/packages/google_mobile_ads/example/lib/snippets/rewarded_ad_snippets.dart#L56-L81\n\n| **Key Point:** Make sure to implement the `onRewardedAdUserEarnedReward` event to reward the user for watching an ad.\n\nDisplay ad\n\nA `RewardedAd` is displayed as an Overlay on top of all app content and is\nstatically placed; thus, it can't be added to the Flutter widget tree. You can\nchoose when to show the ad by calling `show()`.\n`RewardedAd.show()` takes an `OnUserEarnedRewardCallback`, which is invoked when\nthe user earns a reward. Be sure to implement this and reward the user for\nwatching an ad. \n\n _rewardedAd?.show(\n onUserEarnedReward:\n (AdWithoutView ad, RewardItem rewardItem) {\n debugPrint(\n 'Reward amount: ${rewardItem.amount}',\n );\n },\n ); \n https://github.com/googleads/googleads-mobile-flutter/blob/82c58b3202d8b9391e4d3ec39b045032e90cf331/samples/admob/rewarded_example/lib/main.dart#L146-L158\n\nOnce `show()` is called, an `Ad` displayed this way can't be removed\nprogrammatically and requires user input. A `RewardedAd` can only be shown\nonce. Subsequent calls to show will trigger `onAdFailedToShowFullScreenContent`.\n\nAn ad must be disposed when access to it is no longer needed. The best practice\nfor when to call `dispose()` is in the\n`FullScreenContentCallback.onAdDismissedFullScreenContent` and\n`FullScreenContentCallback.onAdFailedToShowFullScreenContent` callbacks.\n\n\\[Optional\\] Validate server-side verification (SSV) callbacks\n\nApps that require extra data in [server-side verification](/admob/flutter/ssv)\ncallbacks should use the custom data feature of rewarded ads. Any string value\nset on a rewarded ad object is passed to the `custom_data` query parameter of\nthe SSV callback. If no custom data value is set, the `custom_data` query\nparameter value won't be present in the SSV callback.\n\nThe following code sample demonstrates how to set the SSV options after the\nrewarded ad is loaded: \n\n RewardedAd.load(\n adUnitId: \"\u003cvar translate=\"no\"\u003e_adUnitId\u003c/var\u003e\",\n request: AdRequest(),\n rewardedAdLoadCallback: RewardedAdLoadCallback(\n onAdLoaded: (ad) {\n ServerSideVerificationOptions _options =\n ServerSideVerificationOptions(\n customData: '\u003cvar translate=\"no\"\u003eSAMPLE_CUSTOM_DATA_STRING\u003c/var\u003e');\n ad.setServerSideOptions(_options);\n _rewardedAd = ad;\n },\n onAdFailedToLoad: (error) {},\n ),\n ); \n https://github.com/googleads/googleads-mobile-flutter/blob/82c58b3202d8b9391e4d3ec39b045032e90cf331/packages/google_mobile_ads/example/lib/snippets/rewarded_ad_snippets.dart#L87-L100\n\nReplace \u003cvar translate=\"no\"\u003eSAMPLE_CUSTOM_DATA_STRING\u003c/var\u003e with your custom data.\n\nComplete example on GitHub\n\n[Rewarded](//github.com/googleads/googleads-mobile-flutter/tree/main/samples/admob/rewarded_example)"]]
