flutter_ads_manager 0.0.4

Drop-in AdMob ads for Flutter: banner, interstitial, rewarded, rewarded interstitial and app open ads with auto-reload, retry, and built-in GDPR consent.

flutter_ads_manager

Drop-in AdMob ads for Flutter. Call init() once, then use AdBannerWidget and AdsManager.instance for every ad type — banner, interstitial, rewarded, rewarded interstitial, and app open — without writing ad-loading code yourself.

Built on google_mobile_ads. It handles:

• Loading, retrying, and reloading ads automatically
• Google's test ad IDs in debug builds, so you never show real ads by accident
• GDPR/UK/US consent (shown automatically before ads load)
• "Show an interstitial every 3rd time" style frequency capping
• Keywords for better ad targeting

AdMob still requires a native App ID in AndroidManifest.xml / Info.plist for every app — that's a Google requirement, not something any package can remove. Everything else is handled for you.

Setup

1. Add the dependency

dependencies:
  flutter_ads_manager: ^0.0.1

2. Add your AdMob App ID

Android — android/app/src/main/AndroidManifest.xml, inside <application>:

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

iOS — ios/Runner/Info.plist:

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

3. Initialize once, at startup

import 'package:flutter/material.dart';
import 'package:flutter_ads_manager/flutter_ads_manager.dart';

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();

  await AdsManager.instance.init(
    adUnitIds: const AdUnitIdSet(
      android: AdUnitIds(
        banner: 'ca-app-pub-xxxxxxxxxxxxxxxx/1111111111',
        interstitial: 'ca-app-pub-xxxxxxxxxxxxxxxx/2222222222',
        rewarded: 'ca-app-pub-xxxxxxxxxxxxxxxx/3333333333',
        rewardedInterstitial: 'ca-app-pub-xxxxxxxxxxxxxxxx/4444444444',
        appOpen: 'ca-app-pub-xxxxxxxxxxxxxxxx/5555555555',
      ),
      ios: AdUnitIds(
        banner: 'ca-app-pub-xxxxxxxxxxxxxxxx/6666666666',
        interstitial: 'ca-app-pub-xxxxxxxxxxxxxxxx/7777777777',
        rewarded: 'ca-app-pub-xxxxxxxxxxxxxxxx/8888888888',
        rewardedInterstitial: 'ca-app-pub-xxxxxxxxxxxxxxxx/9999999999',
        appOpen: 'ca-app-pub-xxxxxxxxxxxxxxxx/0000000000',
      ),
    ),
    showAppOpenOnResume: true, // auto-shows an app open ad on resume
  );

  runApp(const MyApp());
}

That's it — every ad type is now ready to use anywhere in your app.

Usage

Banner

const AdBannerWidget(variant: BannerAdVariant.adaptive)     // full-width, recommended
const AdBannerWidget(variant: BannerAdVariant.standard)     // 320x50
const AdBannerWidget(variant: BannerAdVariant.largeBanner)  // 320x100
const AdBannerWidget(variant: BannerAdVariant.mediumRectangle) // 300x250

Just place it in your layout — it loads itself and shows nothing while loading or if it fails, so it never leaves a gap.

Interstitial

await AdsManager.instance.interstitial.show();

Counted interstitial (every Nth time)

// Shows an interstitial only on the 3rd, 6th, 9th... call for this trigger.
await AdsManager.instance.countedInterstitial.registerEventAndMaybeShow(
  'level_complete',
  every: 3,
);

Rewarded

AdsManager.instance.rewarded.load(); // call ahead of time

if (AdsManager.instance.rewarded.isReady) {
  await AdsManager.instance.rewarded.show(
    onUserEarnedReward: (ad, reward) => grantCoins(reward.amount.toInt()),
  );
}

Rewarded interstitial

Same as rewarded:

await AdsManager.instance.rewardedInterstitial.show(
  onUserEarnedReward: (ad, reward) => grantCoins(reward.amount.toInt()),
);

App open

// Automatic: pass showAppOpenOnResume: true to init().

// Or manually:
await AdsManager.instance.appOpen.show();

Consent (GDPR/UMP)

Handled automatically. If you need a "Privacy options" button in your settings screen:

if (await AdsManager.instance.consent.isPrivacyOptionsRequired) {
  await AdsManager.instance.consent.showPrivacyOptionsForm();
}

Keywords (better ad targeting)

Describe your app or its current content so AdMob can pick more relevant ads:

AdsManager.instance.keywords = ['sports', 'basketball'];

Testing on a real device with real ad unit IDs

await AdsManager.instance.init(
  adUnitIds: ...,
  testDeviceIds: ['33BE2250B43518CCDA7DE426D04EE231'], // printed to console on first request
);

Troubleshooting

An ad shows behind my app's UI (e.g. AppBar visible over an interstitial). This is a known issue on some Android devices, unrelated to this package — the ad's Activity doesn't cover the status bar area the way yours does. Fix it by keeping your app in immersive mode (already done in this repo's example/android/.../MainActivity.kt):

class MainActivity : FlutterActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        WindowCompat.setDecorFitsSystemWindows(window, false)
        WindowInsetsControllerCompat(window, window.decorView)
            .hide(WindowInsetsCompat.Type.systemBars())
    }
}
