--- ## Set Injector listener --- This method sets callbacks for an injector module. **Declared In:** lib/modules/injector/injector_impl.dart **Related To:** [InjectorListener](/developers/mobile-sdk/listeners-and-delegates/react-native-listeners#injector-listener) **Class:** [InjectorImpl](/developers/mobile-sdk/class-reference/flutter/modules#injector) **Declaration:** 
void listener(InjectorListenerFunction listenerFunction)
**Discussion:** Learn more about the methods and their purpose of this listener [here](/developers/mobile-sdk/listeners-and-delegates/flutter-listeners#injector-listener). ## Set In-App Message listener --- This method sets callbacks for in-app message campaigns. **Declared In:** lib/modules/injector/injector_impl.dart **Related To:** [InjectorInAppMessageListener](/developers/mobile-sdk/listeners-and-delegates/react-native-listeners#injector-in-app-message-listener) **Class:** [InjectorImpl](/developers/mobile-sdk/class-reference/flutter/modules#injector) **Declaration:** 
void inAppMessageListener(InjectorInAppMessageListenerFunction listenerFunction)
**Discussion:** Learn more about the methods and their purpose of this listener [here](/developers/mobile-sdk/listeners-and-delegates/flutter-listeners#injector-in-app-message-listener). ## Close in-app message --- Closes an in-app message and sends an `inApp.discard` event. Usage examples: - Closing a top bar or bottom bar when the user taps outside the in-app area. - Automatically dismissing messages when navigating away from a screen. - Controlling in-app visibility based on app logic for a smoother user experience. | | **iOS SDK** | **Android SDK** | **React Native SDK** | **Flutter SDK** | | ----------------------------------------------- | ----------- | --------------- | -------------------- | --------------- | | Introduced in: | 5.7.0 | 6.7.0 | 1.5.0 | 2.5.0 | **Declared In:** lib/modules/injector/injector_impl.dart **Declaration:** 
void closeInAppMessage(String campaignHash)
**Parameters:** | Parameter | Type | Mandatory | Default | Description | | ---------------- | ------ | --------- | ------- | ---------------------------------------- | | **campaignHash** | string | yes | - | Unique identifier of the in-app campaign | ## Register for push notifications --- This method passes the Firebase Token to Synerise for notifications.
- You should call this method every time the user changes the system or application consent for notifications. - The API key must have the `API_PERSONAL_DEVICE_CLIENT_UPDATE` permission from the **Client** group. - If the registration fails, the SDK requests a token update again by a listener/delegate method ([Android](/developers/mobile-sdk/listeners-and-delegates/android-listeners#on-register-for-push-listener), [iOS](/developers/mobile-sdk/listeners-and-delegates/ios-delegates#synerise-delegate-register-for-push-notifications-is-needed), [React Native](/developers/mobile-sdk/listeners-and-delegates/react-native-listeners#notifications-listener), [Flutter](/developers/mobile-sdk/listeners-and-delegates/flutter-listeners#notifications-listener)).
**Declared In:** lib/modules/notifications/notifications_impl.dart **Class:** [NotificationsImpl](/developers/mobile-sdk/class-reference/flutter/modules#notifications)
**Declaration:** 
Future<void> registerForNotifications(String registrationToken,
      {bool? mobileAgreement,
      required void Function() onSuccess,
      required void Function(SyneriseError error) onError})
**Parameters:** | Parameter | Type | Mandatory | Default | Description | | --- | --- | --- | --- | --- | | **registrationToken** | String | yes | - | Firebase Token | | **mobileAgreement** | bool | no | null | Agreement (consent) for receiving mobile push campaigns | | **onSuccess** | Function() | yes | - | Function to be executed when the operation is completed successfully | | **onError** | Function([SyneriseError](/developers/mobile-sdk/class-reference/flutter/miscellaneous#syneriseerror) error) | yes | - | Function to be executed when the operation is completed with an error | **Return Value:** No value is returned.
