avatar_file
Description:
File to the latest cached avatar image, or null
if this contact has no
avatar, or if the avatar data is not yet retrieved.
When avatar_token changes, this property is not updated immediately, but will be updated when the new avatar data is retrieved and stored in cache. Until then, the file will keep its old value of the latest cached avatar image.
This is set to null
if AVATAR_DATA
is not set on this contact. Note that setting
AVATAR_DATA will also implicitly set
AVATAR_TOKEN.
