FTP + metadata

Hello,

Before launching a FlutterFlow project, I'd like some information about the capabilities of the Flutter application.

I need to be able to send media (images jpg, videos mp4 or other) via FTP or SFTP.

I also need to write metadata (XML, IPTC) to the smartphone's files (jpg, mp4).

I need to make API requests to my server and have Flutter process the returned JSON.

Is this possible?

Thanks.
