Is your feature request related to a problem?

I would like to be able to search for attachment metadata for all messages in a channel. I believe only searching for message fields "attachment" and "attachment.type" are supported based on my testing and your documentation here: https://getstream.io/chat/docs/flutter-dart/search/?language=dart

Describe the solution that you'd like

It would be beneficial to have the same query, filtering, and sorting support for attachments. In my app I have a channel "userFiles" and a custom widget that displays all files from this channel. I would like to have the same file searching functionality as a simple OS file explorer or cloud file storage solution such as google drive. I would like the ability for users to search for specific files names, files created after certain dates, etc.

I recognize this may be out of scope for this repository since this is more of a backend feature request. If there is a better place I can submit this feature request please advise.
