Banner Ads

Just write the DFPBanner widget in your favorite place.

DFPBanner(
  isDevelop: true,
  testDevices: MyTestDevices(),
  adUnitId: '/XXXXXXXXX/XXXXXXXXX',
  adSize: DFPAdSize.BANNER,
  onAdLoaded: () {
    print('Banner onAdLoaded');
  },
  onAdFailedToLoad: (errorCode) {
    print('Banner onAdFailedToLoad: errorCode:$errorCode');
  },
  onAdOpened: () {
    print('Banner onAdOpened');
  },
  onAdClosed: () {
    print('Banner onAdClosed');
  },
  onAdLeftApplication: () {
    print('Banner onAdLeftApplication');
  },
),

Manual Ad Refresh

You can manually refresh the banner ads on user interaction, use the onAdViewCreated callback to save an instance of the DFPBannerViewController and then call the reload() method to refresh the ad.

DFPBannerViewController _bannerViewController;

_reload() {
  _bannerViewController?.reload();
}

DFPBanner(
  isDevelop: true,
  testDevices: MyTestDevices(),
  adUnitId: '/XXXXXXXXX/XXXXXXXXX',
  adSize: DFPAdSize.BANNER,
  onAdViewCreated: (controller) {
    _bannerViewController = controller;
  },
  onAdLoaded: () {
    print('Banner onAdLoaded');
  },
  onAdFailedToLoad: (errorCode) {
    print('Banner onAdFailedToLoad: errorCode:$errorCode');
  },
  onAdOpened: () {
    print('Banner onAdOpened');
  },
  onAdClosed: () {
    print('Banner onAdClosed');
  },
  onAdLeftApplication: () {
    print('Banner onAdLeftApplication');
  },
),

About testDevices

If you set isDevelop to true, the test adUnitId will be used.
( If set false, the described adUnitId is used.)
Google Ad Manger needs to register testDevices in case of actual devices.

With this plug-in, you can create the following class and set it to testDevices of DFPBanner.

class MyTestDevices extends TestDevices {
  static MyTestDevices _instance;

  factory MyTestDevices() {
    if (_instance == null) _instance = new MyTestDevices._internal();
    return _instance;
  }

  MyTestDevices._internal();

  @override
  List<String> get values => List()..add("XXXXXXXX"); // Set here.
}

DFPBanner(
  testDevices: MyTestDevices(),
)

About adSize

DFPAdSize is available. This is the same size as that of android.

• BANNER
• FULL_BANNER
• LARGE_BANNER
• LEADERBOARD
• MEDIUM_RECTANGLE
• SMART_BANNER (Only Portrait)

Other custom is also available.

const DFPAdSize.custom({double width, double height}).

About EventListener

The following event listeners are available:

• onAdLoaded
• onAdFailedToLoad
• onAdOpened
• onAdClosed
• onAdLeftApplication

Interstitial Ads

Firstly load it and call the show method at the desired timing.

DFPInterstitialAd _interstitialAd;

@override
void initState() {
  super.initState();

  _interstitialAd = DFPInterstitialAd(
    isDevelop: true,
    adUnitId: "XXXXXXXX",
    onAdLoaded: () {
      print('interstitialAd onAdLoaded');
    },
    onAdFailedToLoad: (errorCode) {
      print('interstitialAd onAdFailedToLoad: errorCode:$errorCode');
    },
    onAdOpened: () {
      print('interstitialAd onAdOpened');
    },
    onAdClosed: () {
      print('interstitialAd onAdClosed');
      interstitialAd.load();
    },
    onAdLeftApplication: () {
      print('interstitialAd onAdLeftApplication');
    },
  );
  _interstitialAd.load();
}

@override
void dispose() {
  _interstitialAd.dispose();
  super.dispose();
}

await interstitialAd.show();

About isDevelop

If you set isDevelop to true, the test adUnitId will be used.
( If set false, the described adUnitId is used.)

About EventListener

The following event listeners are available:

• onAdLoaded
• onAdFailedToLoad
• onAdOpened
• onAdClosed
• onAdLeftApplication

Rewarded Ads

firstly load it and call the show method at the desired timing.

DFPRewardedAd _rewardedAd;
LifecycleEventHandler _lifecycle;

@override
void initState() {
  super.initState();
  _rewardedAd = DFPRewardedAd(
    isDevelop: true,
    adUnitId: "XXXXXXX",
    onAdLoaded: () {
      print('rewardedAd onAdLoaded');
    },
    onAdFailedToLoad: (errorCode) {
      print('rewardedAd onAdFailedToLoad: errorCode:$errorCode');
    },
    onAdOpened: () {
      print('rewardedAd onAdOpened');
    },
    onAdClosed: () {
      print('rewardedAd onAdClosed');
      _rewardedAd.load();
    },
    onAdLeftApplication: () {
      print('rewardedAd onAdLeftApplication');
    },
    onRewarded: (String type, int amount) {
      print('rewardedAd onRewarded: type:$type amount:$amount');
    },
    onVideoStarted: () {
      print('rewardedAd onVideoStarted');
    },
    onVideoCompleted: () {
      print('rewardedAd onVideoCompleted');
    },
  );
  _rewardedAd.load();
  _lifecycle = LifecycleEventHandler(_rewardedAd);
  WidgetsBinding.instance.addObserver(_lifecycle);
}

@override
void dispose() {
  WidgetsBinding.instance.removeObserver(_lifecycle);
  _rewardedAd.dispose();
  super.dispose();
}

await _rewardedAd.show();

It is necessary to call it when resumed and paused, respectively. For that, please implement WidgetsBindingObserver.

class LifecycleEventHandler extends WidgetsBindingObserver {
  final DFPRewardedAd rewardedAd;

  LifecycleEventHandler(this.rewardedAd);

  @override
  didChangeAppLifecycleState(AppLifecycleState state) async {
    switch (state) {
      case AppLifecycleState.inactive:
        break;
      case AppLifecycleState.paused:
        await rewardedAd.pause();
        break;
      case AppLifecycleState.suspending:
        break;
      case AppLifecycleState.resumed:
        await rewardedAd.resume();
        break;
    }
  }
}

About isDevelop

If you set isDevelop to true, the test adUnitId will be used.
