There is not field which represents file size. @filipedelimabrito, is that implemented in server side?

Please follow our coding style (there are indentation issues here.)

@filipedelimabrito, I search docs but not found anything. Is there any field which represents attached file size.
In kotlin SDK, I found Attachment data class, I think it's missed to add fileSize field.
