typedef struct {...} ArkUI_AnimateCompleteCallback Defines the callback type for when the animation playback is complete, which is used to notify you that the animation playback is complete. You can use the type field to specify a callback trigger mode, use the callback field to set a custom callback function, and use the userData field to pass user-defined data to the callback function.

| Name | Description |

| ArkUI_FinishCallbackType type | Callback type for when the animation playback is complete, used to specify how the callback is triggered. The value options are as follows: ARKUI_FINISH_CALLBACK_REMOVED(0) indicates that the callback is triggered when the animation ends and is removed immediately, and ARKUI_FINISH_CALLBACK_LOGICALLY(1) indicates that the callback is triggered when the animation playback is logically complete (it may still be in the tailing state). Different callback types are triggered at different times. Select an appropriate type based on the service scenario. If type is not explicitly set, ARKUI_FINISH_CALLBACK_REMOVED is used. |
| void* userData | Pointer to the user-defined data passed upon the animation playback completion callback. Ensure that userData is still valid when the animation playback completion callback is triggered to avoid undefined behavior caused by a dangling pointer. If this parameter is set to NULL, the callback function will not receive the userData parameter. |

| void (*callback)(void* userData) | Pointer to the callback for when the animation playback is complete. It can be used to perform custom operations after the animation playback ends, such as starting a transition animation, updating the UI element state, or clearing resources. |
void (*callback)(void* userData)
Description
Invoked when the animation playback is complete. It is used together with type and userData. The type parameter determines the timing type for triggering the callback, and the callback function receives userData as an input parameter. After this callback is set, it is automatically invoked when the animation playback ends. You can execute custom logic in the callback through the userData parameter, such as updating the UI state or handling subsequent operations after the animation playback is complete.
