unified_ads_inmobi 📱

InMobi adapter for unified_ads: banner, interstitial and rewarded ads. Adding this package links only the InMobi SDK into your app.

✨ Features

• 🎯 No hardcoding: the Account ID and numeric placement IDs live in your AdConfig (or ads_config.json), and are validated at init.
• 🧩 Three formats, one API: BannerAd + UnifiedBannerWidget, InterstitialAd and RewardedAd. Every ad reports the network that served it (servedBy).
• 🌊 Waterfall fallback: combine InMobi with other networks; if one has no fill, the next is tried.
• ⏱️ 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.
• 🔐 Privacy aware: reads IAB TCF / GPP strings from your CMP, plus explicit GDPR / CCPA / COPPA signals.
• 🪶 Opt-in linking: only the InMobi SDK is added to your APK / IPA.

🚀 Getting Started

1. Add the dependency

dependencies:
  unified_ads: ^1.1.0
  unified_ads_inmobi: ^1.1.0

2. Platform setup

Android

Every dependency (OkHttp, Picasso, media3, coroutines, …) comes through the POM; the AAR ships its ProGuard rules and merges its activities and permissions. Keep android:hardwareAccelerated="true" on <application>.

iOS (ios/Runner/Info.plist)

<key>NSUserTrackingUsageDescription</key>
<string>This identifier will be used to deliver personalized ads to you.</string>
<key>SKAdNetworkItems</key>
<array>
  <dict><key>SKAdNetworkIdentifier</key><string>wzmmz9fp6w.skadnetwork</string></dict>
  <!-- + the full list from InMobi's iOS guidelines -->
</array>

• InMobi requires -ObjC, libz, libsqlite3.0 and WebKit: the adapter's Package.swift links all four, and you should also add -ObjC to Runner → Build Settings → Other Linker Flags (the setting InMobi documents).
• InMobi recommends NSAllowsArbitraryLoads = YES; flag it for App Store review.

📖 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(
    networks: {
      AdNetwork.inmobi: NetworkConfig(
        appId: '<InMobi account ID>',
        bannerAdUnitId: '1234567890',         // placement IDs are NUMERIC (validated at init)
        interstitialAdUnitId: '1234567890',
        rewardedAdUnitId: '1234567890',       // a Rewarded Video placement
      ),
    },
    pacing: {
      AdFormat.interstitial: AdPacing(
        initialDelay: Duration(seconds: 30),
        minInterval: Duration(seconds: 15),
        showEveryActions: 3,
      ),
    },
  ));

  runApp(const MyApp());
}

2. Display a banner ad

final banner = BannerAd(size: BannerSize.standard);   // 320×50, MREC 300×250 or 728×90
// 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) => grant(reward.amount, reward.type),  // from the dashboard reward key/value
);
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 InMobi.

🔑 Getting the IDs

You need: Account ID + numeric placement ID per format.

1. Account: InMobi publisher dashboard → Create Account → verify email. Add an app and a payment method to reach Pending Approval (about 24 working hours).
2. Account ID: top-left corner, under your account name.
3. App: Inventory → Inventory Settings → Add Inventory → Mobile App (store URL) or Unpublished App.
4. Placements: expand the app → + Add a placement → Banner / Interstitial / Rewarded Video (with a reward key/value, e.g. Coins = 1000). The long numeric Placement ID is under the name.
5. Testing: no code-level test flag. Turn test mode on per placement (Global or Device) and register devices under Integration → Integration Testing. With testMode: true the adapter logs at DEBUG so your advertising ID is printed. Turn test mode off before release.

⚙️ Details

Notes

• Test mode (TestModeSupport.none): no code-level test flag. Enable test mode per placement in the InMobi dashboard ("Global ON", or "Selective ON" with your device ID). With testMode on, the adapter switches InMobi logging to DEBUG so the device ID is printed; unified_ads logs a warning at init.
• Rewarded: the reward is the first entry of InMobi's rewards map (name → amount), as configured on the dashboard.
• Banner sizes: no adaptive size. MREC is 300×250, leaderboard 728×90, everything else 320×50.
• Activity: InMobi needs an Activity to show interstitials, so full-screen ads load only while one is attached (otherwise noActivity).

Privacy

IAB TCF / GPP strings from a CMP (e.g. UMP) are read automatically (SDK 10.7.5+). Explicitly: consentGiven / gdprApplies → InMobi's GDPR consent object, ccpaOptOut → InMobiPrivacyCompliance.setDoNotSell, coppa → InMobiSdk.setIsAgeRestricted.

Error mapping (InMobiAdRequestStatus.StatusCode / IMStatusCode)

Status	AdErrorCode
NO_FILL, AD_NO_LONGER_AVAILABLE	noFill
NETWORK_UNREACHABLE, SERVER_ERROR	networkError
REQUEST_TIMED_OUT	timeout
REQUEST_INVALID, CONFIGURATION_ERROR, MONETIZATION_DISABLED, MISSING_REQUIRED_DEPENDENCIES	invalidConfig
AD_ACTIVE	alreadyShowing
other	internal

🛠️ Verification & Tests

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

Android: the SDK initializes and requests round-trip on a device; InMobi's sample placements return NO_FILL for this package, so serving needs your own placements (dashboard test mode). iOS builds in CI and hasn't run on a physical device yet.
