unified_ads_facebook 📱

Facebook Audience Network (branded Meta Audience Network) adapter for unified_ads: banner, interstitial and rewarded.

✨ Features

• 🎯 No hardcoding: placement IDs live in your AdConfig (or ads_config.json). No App ID is needed in code.
• 🧩 Three formats, one API: BannerAd + UnifiedBannerWidget, InterstitialAd and RewardedAd. Every ad reports the network that served it (servedBy).
• 🌊 Waterfall fallback: keep Audience Network last in the waterfall; earlier networks are tried first.
• 🛡️ Safe test mode: test placements (IMG_16_9_APP_INSTALL#…) or registered test devices.
• ⏱️ Pacing and frequency caps: set a cooldown between interstitials, show one every N user actions, skip the first seconds after launch, and cap shows per time window.
• 👑 Pro users and ad-free mode: UnifiedAds.setAdFree(true) collapses banners and blocks interstitials.
• 🪶 Opt-in linking: apps that don't depend on this package never pull the Audience Network SDK.

	Android	iOS
SDK	com.facebook.android:audience-network-sdk:6.22.0	FBAudienceNetwork 6.22.1
Minimum	minSdk 24 (package)	iOS 15.0 (higher than the other adapters)
Distribution	Gradle	Swift Package Manager (github.com/facebook/FBAudienceNetwork, dynamic xcframework)

Read this first. Audience Network has been bidding-only since 2021. A direct integration like this one serves test ads (test placements IMG_16_9_APP_INSTALL#<placement id> or registered test devices), but it is not expected to fill in production. For Facebook revenue, add Audience Network as a bidder in AdMob, AppLovin MAX or LevelPlay mediation (see Meta bidding); those ads are then served by admob / applovin / ironsource. Keep this adapter last in the waterfall (or out of production builds) unless Meta has enabled direct delivery for your property.

🚀 Getting Started

1. Add the dependency

dependencies:
  unified_ads: ^1.1.0
  unified_ads_facebook: ^1.1.0

2. Platform setup

Android

Cleartext for 127.0.0.1 is required. The SDK plays cached media through a local proxy, which Android 9+ blocks (AdError 7003 CLEAR_TEXT_SUPPORT_NOT_ALLOWED). Allow cleartext for that host only:

android/app/src/main/res/xml/network_security_config.xml

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">127.0.0.1</domain>
    </domain-config>
</network-security-config>

AndroidManifest.xml:

<application android:networkSecurityConfig="@xml/network_security_config" ...>

If your app already has a network security config, add the domain-config to it (the library doesn't ship one, because an app can have only one). No manifest meta-data or App ID is needed; R8 rules ship inside the SDK AAR.

iOS

• Deployment target 15.0 on the Runner target (IPHONEOS_DEPLOYMENT_TARGET). With 13.0 the build fails.

• SKAdNetwork: v9wttpbfk9.skadnetwork and n38lu8286q.skadnetwork (the whole list) in SKAdNetworkItems:

  <key>SKAdNetworkItems</key>
  <array>
    <dict><key>SKAdNetworkIdentifier</key><string>v9wttpbfk9.skadnetwork</string></dict>
    <dict><key>SKAdNetworkIdentifier</key><string>n38lu8286q.skadnetwork</string></dict>
  </array>
  

• ATT: add NSUserTrackingUsageDescription and call UnifiedAds.requestTrackingAuthorization() before init. On iOS 15–16 the adapter sets FBAdSettings.setAdvertiserTrackingEnabled from the ATT status, as Meta requires below iOS 17; on iOS 17+ SDK 6.15+ reads the status itself and the setter is deprecated, so it isn't called.

• loadAd has been deprecated since 6.11 ("use loadAdWithBidPayload") because of bidding. It's still the direct-load path and produces a compiler warning. Meta has said 6.22.x is the last CocoaPods series.

• Pin compatibility: this package pins FBAudienceNetwork exact 6.22.1, like AppLovin's (6220100.0.0) and LevelPlay's (5.6.0) Meta adapters. Google's Meta adapter (6.22.000) pins 6.22.0, so it can't share an iOS app with this version.

📖 Usage

1. Initialize at app launch

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

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

  await UnifiedAds.setAdFree(await isProUser());    // optional, see step 5
  await UnifiedAds.requestTrackingAuthorization();  // iOS prompt; Android: notApplicable
  await UnifiedAds.init(AdConfig(
    waterfall: [AdNetwork.facebook],                 // keep it last next to other networks
    networks: {
      AdNetwork.facebook: NetworkConfig(
        // Audience Network needs no app ID in code.
        bannerAdUnitId: 'IMG_16_9_APP_INSTALL#YOUR_BANNER_PLACEMENT_ID',
        interstitialAdUnitId: 'IMG_16_9_APP_INSTALL#YOUR_INTERSTITIAL_PLACEMENT_ID',
        rewardedAdUnitId: 'IMG_16_9_APP_INSTALL#YOUR_REWARDED_PLACEMENT_ID',
        testMode: true,
        testDeviceIds: ['<hashed id printed by the SDK in logcat / Xcode console>'],
        extras: {'rewardAmount': 1, 'rewardType': 'coins'}, // reward reported to Dart
      ),
    },
    pacing: {
      AdFormat.interstitial: AdPacing(
        minInterval: Duration(seconds: 15),
        showEveryActions: 3,
      ),
    },
  ));

  runApp(const MyApp());
}

2. Display a banner ad

final banner = BannerAd(size: BannerSize.standard);   // use a banner-format placement
// build():   UnifiedBannerWidget(ad: banner, anchored: true)
// dispose(): banner.dispose();

3. Show paced interstitial ads

final interstitial = InterstitialAd(onClosed: (ad) => goToNextScreen());
await interstitial.load();

await UnifiedAds.recordAction();                 // after each user action
if (await interstitial.canShow()) {
  await interstitial.show();
} else {
  goToNextScreen();                              // paced, capped or ad-free: skip
}

4. Show rewarded video ads

final rewarded = RewardedAd(
  onEarnedReward: (ad, reward) => grantCoins(reward.amount),   // from extras['rewardAmount']
);
if ((await rewarded.load()).isSuccess) await rewarded.show();

5. Pro users / ad-free mode

await UnifiedAds.setAdFree(true);                      // banners + interstitials off
await UnifiedAds.setAdFree(true, blockRewarded: true); // rewarded off too

Blocked calls return AdErrorCode.adsBlocked without contacting Audience Network.

🔑 Getting the IDs

You need: placement IDs only.

1. Sign in to Monetization Manager → Create Property (Business Manager required) → add the Android and/or iOS platform.
2. Create placement per format (Banner, Interstitial, Rewarded video). The Placement ID (<number>_<number>) is in the Placements table. A placement only serves its own format (a mismatch fails with 1011/1203 → invalidConfig).
3. Testing: prefix the placement ID with IMG_16_9_APP_INSTALL# for a test creative, or add the device hash the SDK logs (Test mode device hash: …) to testDeviceIds with testMode: true. Drop the prefix in release builds.
4. Production: Audience Network is bidding-only; direct requests aren't expected to fill. Add it as a bidder in AdMob, MAX or LevelPlay (Meta bidding).

⚙️ Details

Notes

• Placements must match their display format (banner placement for BannerAd, and so on). A mismatch fails with native 1011/1203 → invalidConfig.
• Test mode (TestModeSupport.testDevices): the SDK logs Test mode device hash: … on the first request. Put it in testDeviceIds with testMode: true (→ AdSettings.addTestDevices). The IMG_16_9_APP_INSTALL# prefix forces a test creative without registering a device. On iOS (since 1.0.1), testMode: true with empty testDeviceIds registers the current device, because iOS serves no test ads to an unregistered device, even on the simulator.
• Rewards: "video completed" has no amount; onEarnedReward uses extras['rewardAmount'] / extras['rewardType'] (default 1 / 'reward'). Server-side reward verification is not implemented yet.

Credits

The SDK call shapes were cross-checked against the (abandoned, MIT-licensed) facebook_audience_network plugin and Google's official Meta mediation adapters. No code was copied. Every API name was verified against the 6.22.0 SDK binaries/headers.

🛠️ Verification & Tests

flutter test                        # adapter unit tests (mocked host API)
cd example && flutter run           # the shared example app: enable Facebook in Settings

Android verified on a physical device with public test placements: init, banner (+ impression), interstitial load + show. Rewarded needs your own rewarded-format placement (no public one exists). iOS builds in CI and hasn't run on a physical device yet.
