enablePreloadMessageAttachment property Null safety

bool? enablePreloadMessageAttachment

Specify whether to automatically pre-load the attachment of a multimedia message. If the option is enabled, after the SDK receives multimedia messages, thumbnails for images and video messages will be downloaded. Audio files will be automatically downloaded. If disabled, the third-party app can only decide whether to download and when to download the attachment content. In most cases, when the message list is swiped for the first time, the app can make the decision. The download is triggered only when this message is loaded when users swipe the screen. By default, the setting is enabled.
