data class Animation(val fileId: String, val fileUniqueId: String, val width: Int, val height: Int, val duration: Int, val thumbnail: PhotoSize? = null, val fileName: String? = null, val mimeType: String? = null, val fileSize: Long? = null)
This object represents an animation file (GIF or H.264/MPEG-4 AVC video without sound).
Optional. File size in bytes. It can be bigger than 2^31 and some programming languages may have difficulty/silent defects in interpreting it. But it has at most 52 significant bits, so a signed 64-bit integer or double-precision float type are safe for storing this value.
