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');
  },
),

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


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

Other custom is also available.

About EventListener

Event listeners are also available.
However, ios does not work. (I am conducting an investigation, but I do not know yet.) If you really want to use it, you can use listener by bringing Plugin source to your application.

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

It is similar to the above Banner.
It does not work on ios.

Because of this, it can not be reloaded after closing, so it can not be displayed twice on the same screen.

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.
( If set false, the described adUnitId is used.)

About EventListener

Event listeners are also available.
This also works with ios and android.

Native Ads

Not implemented.
I am glad if someone will give me a pull request.
