Attachment

@Immutable

data class Attachment(val authorName: String? = null, val authorLink: String? = null, val titleLink: String? = null, val thumbUrl: String? = null, val imageUrl: String? = null, val assetUrl: String? = null, val ogUrl: String? = null, val mimeType: String? = null, val fileSize: Int = 0, val title: String? = null, val text: String? = null, val type: String? = null, val image: String? = null, val name: String? = null, val fallback: String? = null, val originalHeight: Int? = null, val originalWidth: Int? = null, val upload: File? = null, val uploadState: Attachment.UploadState? = null, val extraData: Map<String, Any> = mapOf()) : CustomObject

Represents an attachment. Most commonly these are files, images, videos and audio recordings, but the class is flexible enough that it can represent other things as well such as a date, a given location or other things.

If you want to create a custom attachment we suggest you use extraData to store the information you need.
