mc_sdk 1.1.0

A multi-mediation advertising SDK for Flutter, bridging MAX, AdMob, GroMore and TopOn, with banner, MREC, interstitial, rewarded, app-open and native ad formats.

MCSDK Flutter Plugin

A multi-mediation advertising SDK for Flutter. mc_sdk bridges the native MCSDK on Android and iOS, giving you a single Dart API across mediation networks such as MAX, AdMob, GroMore and TopOn.

Features

• Ad formats: Banner, MREC, Interstitial, Rewarded, App-Open and Native ads.
• Smart Cache: built-in preloading APIs for interstitial, rewarded and app-open ads.
• Privacy controls: user consent, age-restricted user, and do-not-sell flags.
• Mediation debugger and runtime mediation-switch callbacks.

Platform support

Platform	Minimum version
Android	minSdkVersion 16
iOS	13.0

Installation

Add the dependency to your app's pubspec.yaml:

dependencies:
  mc_sdk: ^1.1.0

Then run:

flutter pub get

Native SDK setup is required. This plugin is a bridge to the native MCSDK. Your host app must also integrate the native MCSDK dependencies (Android and iOS) and configure the platform App ID / App Key. Follow the HyperBid Flutter integration guide before using the APIs below.

Usage

Initialize

Call initialize once, early in your app's lifecycle:

import 'package:mc_sdk/mc_sdk.dart';

final config = await McSdk.initialize(appId, appKey);

Interstitial

McSdk.setInterstitialListener(McInterstitialListener(
  onAdLoadedCallback: (ad) => print('loaded'),
  onAdLoadFailedCallback: (adUnitId, error) => print('failed: ${error.code}'),
  onAdDisplayedCallback: (ad) {},
  onAdHiddenCallback: (ad) {},
  onAdClickedCallback: (ad) {},
));

McSdk.loadInterstitial(interstitialAdUnitId);

if (await McSdk.isInterstitialReady(interstitialAdUnitId) ?? false) {
  McSdk.showInterstitial(interstitialAdUnitId);
}

Rewarded

McSdk.setRewardedAdListener(McRewardedAdListener(
  onAdLoadedCallback: (ad) {},
  onAdLoadFailedCallback: (adUnitId, error) {},
  onAdDisplayedCallback: (ad) {},
  onAdClickedCallback: (ad) {},
  onAdHiddenCallback: (ad) {},
  onAdReceivedRewardCallback: (ad, reward) {},
  onAdFailedToReceivedRewardCallback: (ad) {},
));

McSdk.loadRewardedAd(rewardedAdUnitId);
McSdk.showRewardedAd(rewardedAdUnitId);

Banner

McSdk.setBannerListener(McAdViewAdListener(
  onAdLoadedCallback: (ad) {},
  onAdLoadFailedCallback: (adUnitId, error) {},
  onAdClickedCallback: (ad) {},
));

McSdk.createBanner(bannerAdUnitId, AdViewPosition.bottomCenter);
McSdk.showBanner(bannerAdUnitId);
// ...
McSdk.hideBanner(bannerAdUnitId);
McSdk.destroyBanner(bannerAdUnitId);

Smart Cache

For automatically preloaded fullscreen ads:

McSdk.setSmartCacheInterstitialListener(/* ... */);
McSdk.smartLoadInterstitial();

if (await McSdk.smartIsInterstitialReady() ?? false) {
  McSdk.smartShowInterstitial();
}

Native ads

Use the McNativeAdView widget exported by the package to render native ads inside your layout. See the example/ app for a complete integration.

Privacy

McSdk.setHasUserConsent(true);
McSdk.setIsAgeRestrictedUser(false);
McSdk.setDoNotSell(false);

Example

A full sample app is available under example/, covering every ad format and the Smart Cache APIs.
