Dream Monet Flutter SDK

---

1. Install

Trong pubspec.yaml:

  dependencies:
    dream_monet_flutter_sdk: ^0.0.9-alpha

---

2. Setup Application ID KEY

Android

1. Đảm bảo minSdkVersion >= 21, compileSdkVersion mới nhất và MainActivity đã khai báo android:exported.
2. Thêm App ID của Google Mobile Ads vào android/app/src/main/AndroidManifest.xml:

<application>

    <meta-data
        android:name="com.google.android.gms.ads.APPLICATION_ID"
        android:value="ca-app-pub-3940256099942544~3347511713" />

    <!-- MainActivity -->
</application>

iOS (Chưa test)

• Thêm GADApplicationIdentifier vào ios/Runner/Info.plist.
• Bổ sung SKAdNetworkItems theo hướng dẫn của Google nếu cần attribution.

---

3. Khởi tạo SDK & Consent

In your splash screen

final DreamMonetSDK sdk = DreamMonetSDK();

Future<void> bootstrap() async {
  WidgetsFlutterBinding.ensureInitialized();
  await MobileAds.instance.initialize();

  final config = SDKConfig(
    appId: SampleAdUnits.admobAppId,
    isDebugMode: true,
    testMode: true
  );
  await sdk.initialize(config);

  final result = await sdk.consentManager.gatherConsent(
    testDeviceHashedId: SampleAdUnits.testDeviceId,
    debugGeography: DebugGeography.debugGeographyEea,
  );

  if (!result.isSuccess) throw result.message ?? 'Consent error';
  if (!await sdk.consentManager.canRequestAds()) {
    throw 'Consent chưa sẵn sàng để request ads';
  }
}

---

4. Tích hợp

Interstitial

late final CommonInterstitialAd _interstitialAd = CommonInterstitialAd(
  key: 'demo-interstitial-key',
  defaultUnitId: SampleAdUnits.interstitialAdUnit,
);

Future<void> _loadInterstitial() async {
  final result = await _interstitialAd.load(context);
}

void _showInterstitial() {
  _interstitialAd.show(
    context,
    _InterstitialCallback(
      onShowed: () { /* do something */ },
      onFailed: (error) {  }
    ),
    timeoutMs: 5000,
  );
}

• CommonInterstitialAd.load trả về DreamLoadResult để bạn quyết định flow.

Rewarded

late final CommonRewardedAd _rewardedAd = CommonRewardedAd(
  key: 'demo-rewarded-key',
  defaultUnitId: SampleAdUnits.rewardedAdUnit,
);


//optional for reward ad
_rewardedAd.setServerSideVerificationOptions(ServerSideVerificationOptions(userId: "hello my feng"));

//load
Future<void> _loadRewarded() async {
  final result = await _rewardedAd.load(context);
}

//show
void _showRewarded() {
  _rewardedAd.show(
    context,
    _RewardedCallback(
      onShowed: () { /* do something */ },
      onFailed: (error) {  },
      onRewarded: (amount, type) => _log('Rewarded user (+$amount $type)'),
    ),
    timeoutMs: 5000,
  );
}

5. In App Purchase

• Cấu hình trong SDKConfig khi khởi tạo SDK:

final config = SDKConfig(
  appId: 'your_app_id',
  purchaseConfig: DreamPurchaseConfig(
    android: PlatformPurchaseConfig(
      consumableIds: ['coin_pack_1', 'coin_pack_2'],
      oneTimeProductIds: ['remove_ads'],
      subscriptionIds: ['premium_monthly'],
      removeAdIds: ['remove_ads'],
    ),
    ios: PlatformPurchaseConfig(
      consumableIds: ['coin_pack_1'],
      oneTimeProductIds: ['remove_ads'],
      subscriptionIds: ['premium_monthly'],
      removeAdIds: ['remove_ads'],
    ),
  ),
);

final purchase = DreamMonetSDK().purchase;

final price = await purchase.getPrice('product_id');
final currency = await purchase.getCurrency('product_id');

//buy
final result = await purchase.buy('product_id');
if (result == null) {

} else if (result.status == DreamPurchaseStatus.error) {
print('Lỗi: ${result.error?.message}');
} else if (result.isPurchased()){
print('Mua hàng thành công!');
}

// check if remove ad by purchase:
purchase.isRemoveAd // a bool value
purchase.isRemoveAdStream.listen((isRemoveAd) => _log("removed ad")); //stream

6. Ad Revenue Listener

To listen for ad revenue events (e.g., to send data to MMPs like AppsFlyer or Adjust), implement the AdRevenueListener interface and register it with the SDK before initialization.

1. Create a Listener Class

import 'package:dream_monet_flutter_sdk/dream_monet_flutter_sdk.dart';

class MyAppRevenueListener extends AdRevenueListener {
  @override
  void onAdRevenue(
    String adId,
    int valueMicros,
    String currencyCode,
    String precision,
  ) {
    print('Ad Revenue: $valueMicros $currencyCode (Precision: $precision) for Ad Unit: $adId');

    // Example: Log to AppsFlyer
    // final revenue = valueMicros / 1000000.0;
    // Map<String, dynamic> additionalParams = {
    //   'adUnitId': adId,
    //   'precision': precision,
    // };
    // appsFlyerSdk.logAdRevenue(revenue, currencyCode, additionalParams);
  }
}

2. Register the Listener

Call setAdRevenueListener before initializing the SDK.

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  
  // Register revenue listener
  DreamMonetSDK().setAdRevenueListener(MyAppRevenueListener());

  // Initialize SDK
  final config = SDKConfig(
    // ... your config
  );
  await DreamMonetSDK().initialize(config);
  
  // ... rest of your app initialization
}
