void main() {
  UnityAds.init(
    gameId: 'YOUR_GAME_ID',
    testMode: true,

Getting Started

1. Initialization

UnityAds.init(
  gameId: 'PROJECT_GAME_ID',
  onComplete: () => print('Initialization Complete'),
  onFailed: (error, message) => print('Initialization Failed: $error $message'),
);

Set your Game ID. For testing purposes, set testMode to true.

UnityAds.isInitialized() can be used to check if the SDK has initialized successfully.

---

Android only: To change ad behavior in Firebase Test Lab, use the firebaseTestLabMode parameter. Possible values:

Mode	Description
disableAds	Ads are not displayed in Firebase Test Lab (default)
showAdsInTestMode	Ads are displayed in test mode.
showAds	Real ads are displayed if testMode is false.

2. Show Rewarded/Interstitial Video Ad

Load a video ad before showing it.

UnityAds.load(
  placementId: 'PLACEMENT_ID',
  onComplete: (placementId) => print('Load Complete $placementId'),
  onFailed: (placementId, error, message) => print('Load Failed $placementId: $error $message'),
);

Show a loaded ad.

UnityAds.showVideoAd(
  placementId: 'PLACEMENT_ID',
  onStart: (placementId) => print('Video Ad $placementId started'),
  onClick: (placementId) => print('Video Ad $placementId click'),
  onSkipped: (placementId) => print('Video Ad $placementId skipped'),
  onComplete: (placementId) => print('Video Ad $placementId completed'),
  onFailed: (placementId, error, message) => print('Video Ad $placementId failed: $error $message'),
);

Server-to-server Redeem Callbacks

UnityAds.showVideoAd has a serverId parameter. To use server-to-server callbacks, set this parameter. Read more at docs.unity.com.

3. Show Banner Ad

Place the UnityBannerAd widget in your app.

UnityBannerAd(
  placementId: 'PLACEMENT_ID',
  onLoad: (placementId) => print('Banner loaded: $placementId'),
  onClick: (placementId) => print('Banner clicked: $placementId'),
  onShown: (placementId) => print('Banner shown: $placementId'),
  onFailed: (placementId, error, message) => print('Banner Ad $placementId failed: $error $message'),
)
