Getting Started

To get started with easy_admob_ads_flutter, follow the steps below to integrate AdMob ads into your Flutter app.

1. Install the package

Add the dependency in your pubspec.yaml:

dependencies:
  easy_admob_ads_flutter: ^<latest_version>

Replace <latest_version> with the latest version on pub.dev

OR install it directly via terminal:

flutter pub add easy_admob_ads_flutter

2. Configure platform-specific AdMob setup

Android

• Open your android/app/src/main/AndroidManifest.xml
• Add your AdMob App ID inside the <application> tag:

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

iOS

• Open your ios/Runner/Info.plist and add:

<key>GADApplicationIdentifier</key>
<string>ca-app-pub-xxxxxxxxxxxxxxxx~yyyyyyyyyy</string>

3. Initialize the SDK and pass your Ad Unit IDs

Inside your main.dart:

void main() async {
  // Ensure platform bindings are initialized before any async calls
  WidgetsFlutterBinding.ensureInitialized();

  // Set your actual AdMob App IDs in AndroidManifest.xml and Info.plist:
  // Android: https://developers.google.com/admob/flutter/quick-start#android
  // iOS:    https://developers.google.com/admob/flutter/quick-start#ios

  // Sets up global logging for Easy Admob Ads Flutter Package
  AdHelper.setupAdLogging();

  // Initialize ad unit IDs for Android and/or iOS (required for at least one)
  // Leave any value as an empty string ("") to skip that ad type.
  AdIdRegistry.initialize(
    ios: {
      AdType.banner: 'ca-app-pub-3940256099942544/8388050270', // Test ID
      AdType.interstitial: 'ca-app-pub-3940256099942544/4411468910', // Test ID
      AdType.rewarded: 'ca-app-pub-3940256099942544/1712485313', // Test ID
      AdType.rewardedInterstitial: 'ca-app-pub-3940256099942544/6978759866', // Test ID
      AdType.appOpen: 'ca-app-pub-3940256099942544/5575463023', // Test ID
      AdType.native: 'ca-app-pub-3940256099942544/3986624511', // Test ID
    },
    android: {
      AdType.banner: 'ca-app-pub-3940256099942544/2014213617', // Test ID
      AdType.interstitial: 'ca-app-pub-3940256099942544/1033173712', // Test ID
      AdType.rewarded: 'ca-app-pub-3940256099942544/5224354917', // Test ID
      AdType.rewardedInterstitial: 'ca-app-pub-3940256099942544/5354046379', // Test ID
      AdType.appOpen: 'ca-app-pub-3940256099942544/3419835294', // Test ID
      AdType.native: 'ca-app-pub-3940256099942544/2247696110', // Test ID
    },
  );

  // Global Ad Configuration
  AdHelper.showAds = true; // Set to false to disable all ads globally
  // AdHelper.showAppOpenAds = true; // Set to false to disable App Open Ad on startup

  // AdHelper.showConstentGDPR = true; // Simulate GDPR consent (debug only, false in release)

  // Initialize Google Mobile Ads SDK
  await AdmobService().initialize();

  // Optional: Use during development to test if all ad units load successfully
  // await AdRealIdValidation.validateAdUnits();

  runApp(const MainApp());
}

See the full example in the example/ folder of this repository for complete usage of all ad types with interactive UI.

Usage

After initializing AdMob and registering your ad unit IDs, you can use the following widgets and classes to display ads:

Banner Ad

AdmobBannerAd(collapsible: true, height: 100)

Native Ad

AdmobNativeAd.medium()

Interstitial Ad

final interstitialAd = AdmobInterstitialAd();
interstitialAd.loadAd();
interstitialAd.showAd();

Rewarded Ad

final rewardedAd = AdmobRewardedAd(
  onRewardEarned: (reward) {
    // Grant the user a reward
  },
);
rewardedAd.loadAd();
rewardedAd.showAd();

Rewarded Interstitial Ad

final rewardedInterstitialAd = AdmobRewardedInterstitialAd(
  onRewardEarned: (reward) {
    // Grant reward here
  },
);
rewardedInterstitialAd.loadAd();
rewardedInterstitialAd.showAd();

App Open Ad

final appOpenAd = AdmobAppOpenAd();
appOpenAd.loadAd();
appOpenAd.showAdIfAvailable();

You can also control when App Open ads show automatically using: AdHelper.showAppOpenAds = true;

GDPR Consent (UMP)

final consentManager = ConsentManager();

if (AdHelper.isPrivacyOptionsRequired) ...[
ElevatedButton(
  onPressed: () {
    consentManager.showPrivacyOptionsForm((formError) {
      if (formError != null) {
        debugPrint("${formError.errorCode}: ${formError.message}");
        if (context.mounted) {
          ScaffoldMessenger.of(context).showSnackBar(const SnackBar(content: Text("The privacy options form is unavailable because it is not required.")));
        }
      }
    });
  },
  child: Text("Show GDPR Ad Privacy"),
),

This ensures GDPR compliance using Google’s User Messaging Platform (UMP). Use AdHelper.showConstentGDPR = true in debug builds to simulate consent for testing.
