# Events

There is a bunch of events which informs you about the placement state. For example you can figure out when placement is loaded by registering function to the `onHaveAd` field of the `AATKitBinding` object, like:

```dart
  @override
  void initState() {
    super.initState();
    _aatKitBinding.onHaveAd = (placementName) {
      print("[Home Page] onHaveAd placementName: $placementName");
    };
  }
```

#### Function(String)? onHaveAd <a href="#markdown-header-functionstring-onhavead" id="markdown-header-functionstring-onhavead"></a>

Notifies that placement has finished loading an ad successfully.

```dart
  @override
  void initState() {
    super.initState();da
    _aatKitBinding.onHaveAd = (placementName) {
      print("[Home Page] onHaveAd placementName: $placementName");
    };
  }
```

#### Function(String)? onNoAd <a href="#markdown-header-functionstring-onnoad" id="markdown-header-functionstring-onnoad"></a>

Notifies that placement has failed to load an ad.

```dart
  @override
  void initState() {
    super.initState();
    _aatKitBinding.onNoAd = (placementName) {
      print("[Home Page] onNoAd placementName: $placementName");
    };
  }
```

#### Function(String)? onPauseForAd <a href="#markdown-header-functionstring-onpauseforad" id="markdown-header-functionstring-onpauseforad"></a>

Notifies that ad went fullscreen and that application should pause.

```dart
  @override
  void initState() {
    super.initState();
    _aatKitBinding.onPauseForAd = (placementName) {
      print("[Home Page] onPauseForAd placementName: $placementName");
    };
  }
```

#### Function(String)? onResumeAfterAd <a href="#markdown-header-functionstring-onresumeafterad" id="markdown-header-functionstring-onresumeafterad"></a>

Notifies that ad came back from fullscreen and that application should resume.

```dart
  @override
  void initState() {
    super.initState();
    _aatKitBinding.onResumeAfterAd = (placementName) {
      print("[Home Page] onResumeAfterAd placementName: $placementName");
    };
  }
```

#### Function(AATKitReward)? onUserEarnedIncentive <a href="#markdown-header-functionaatkitreward-onuserearnedincentive" id="markdown-header-functionaatkitreward-onuserearnedincentive"></a>

Notifies that placement has earned incentive (by rewarded ads)

```dart
  @override
  void initState() {
    super.initState();
    _aatKitBinding.onUserEarnedIncentive = (reward) {
      print("[Home Page] onUserEarnedIncentive "
          "placementName: ${reward.placementName} "
          "rewardName: ${reward.rewardName} "
          "rewardValue: ${reward.rewardValue} ");
    };
  }
```

#### Function(AATKitConsentState)? managedConsentCMPFinished <a href="#markdown-header-functionaatkitconsentstate-managedconsentcmpfinished" id="markdown-header-functionaatkitconsentstate-managedconsentcmpfinished"></a>

Notifies that the used CMP has finished updating consent.

```dart
  @override
  void initState() {
    super.initState();
    _aatKitBinding.managedConsentCMPFinished = (state) {
      print("[Home Page] managedConsentCMPFinished state: $state");
    };
  }
```

#### Function()? managedConsentNeedsUserInterface <a href="#markdown-header-function-managedconsentneedsuserinterface" id="markdown-header-function-managedconsentneedsuserinterface"></a>

Notifies that Managed Consent needs to show a consent dialog.

```dart
  @override
  void initState() {
    super.initState();
    _aatKitBinding.managedConsentNeedsUserInterface = () {
      print("[Home Page] managedConsentNeedsUserInterface");
    };
  }
```

#### Function(String)? managedConsentCMPFailedToShow <a href="#markdown-header-functionstring-managedconsentcmpfailedtoshow" id="markdown-header-functionstring-managedconsentcmpfailedtoshow"></a>

Notifies that the used CMP failed to show.

```dart
  @override
  void initState() {
    super.initState();
    _aatKitBinding.managedConsentCMPFailedToShow = (error) {
      print("[Home Page] managedConsentCMPFailedToShow error: $error");
    };
  }
```

#### Function(String)? managedConsentCMPFailedToLoad <a href="#markdown-header-functionstring-managedconsentcmpfailedtoload" id="markdown-header-functionstring-managedconsentcmpfailedtoload"></a>

Notifies that the used CMP failed to load.

```dart
  @override
  void initState() {
    super.initState();
    _aatKitBinding.managedConsentCMPFailedToLoad = (error) {
      print("[Home Page] managedConsentCMPFailedToLoad error: $error");
    };
  }
```
