✨ Features

• 🛡️ Zero DI Lock-in: Fully standalone. Works out of the box with Riverpod, BLoC/Cubit, Provider, GetX, or vanilla Flutter without requiring injectable or get_it.
• ⚙️ One-Line Production/Test Switching: Switch seamlessly between official Google test ads and production AdMob units using AdManager.setRealAds(...).
• 💎 Reactive "Remove Ads" (IAP): Instantly hide and dispose all mounted banner and native ads across the widget tree with AdManager.setAdsEnabled(false).
• 🎨 Custom / House Ads & Offline Fallbacks: Render promotional or offline ads (CustomAdModel) with asset/network images, custom badges, and centralized click routing (AdManager.onCustomAdClicked).
• 📊 Unified Analytics Telemetry: Capture all lifecycle events (Loaded, Failed, Showed, Dismissed, Clicked, Impression, Paid / ILRD, Reward Earned) via AdManager.onAdEvent or AdManager.adEventStream for logging to Firebase Analytics, Adjust, AppsFlyer, etc.
• 🤖 Agentic Coding Ready (SKILL.md): Includes official agent skill instructions in .agents/skills/flutter-prakash-ads/SKILL.md for AI pair programmers and autonomous coding assistants.
• 📐 Anchored Adaptive Banners: Built-in SmartBannerAdView.getAnchoredAdaptiveAdSize(context) to maximize fill rates and eCPMs.
• 🌐 Smart Network Awareness: Real-time network detection with seamless fallback widgets when offline or when AdMob fails to fill.
• 👶 COPPA & Google Play Families Policy Ready: Configure child-directed treatment, age of consent, and content rating tags with AdManager.updateRequestConfiguration(...).
• 🔒 GDPR / UMP Consent Ready: Built-in ConsentManager for EEA/UK GDPR compliance and privacy options revocation forms.
• ⏱️ AdMob & Play Policy Guardrails:
  • Anti-Stacking Collision: Prevents App Open, Interstitial, and Rewarded ads from ever presenting simultaneously.
  • 4-Hour Max-Age Expiration: Automatically evicts stale cached impressions.
  • 30s Interstitial Throttling: Prevents rapid ad spam and user fatigue.
  • App Open Cold-Start & Background Guards: 4-second timeout deadline and 15-second background threshold.
  • CLS Prevention: Fixed dimensional bounding prevents Cumulative Layout Shifts and accidental clicks.

2. Display Adaptive / Standard Banner Ads

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

class MyBannerPage extends StatelessWidget {
  const MyBannerPage({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text('Banner Ad Example')),
      body: const Center(child: Text('Content Area')),
      bottomNavigationBar: const SafeArea(
        child: SmartBannerAdView(
          adSize: AdSize.banner, // or use default anchored adaptive
          showOfflineFallback: true,
        ),
      ),
    );
  }
}

---

3. Display Native Ads (Small & Medium Templates)

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

// Small Native Ad (90px height)
const SmartNativeAdView(
  templateType: TemplateType.small,
  cornerRadius: 12.0,
);

const SmartNativeAdView(
  templateType: TemplateType.medium,
  cornerRadius: 12.0,
);

---

4. Full-Screen Interstitial & Rewarded Ads

final adsService = AdsServiceImpl();

// 1. Preload Interstitial
adsService.loadInterstitialAd();

// 2. Show Interstitial (with 30s policy throttling & collision lock)
adsService.showInterstitialAd(
  onAdDismissedFullScreenContent: () {
    // Navigate to next screen
  },
);

// 3. Show Rewarded Video Ad
adsService.showRewardedAd(
  onUserEarnedReward: (ad, reward) {
