Add Documentation for Prep Flow classes and methods

[thechadd]

Hi!
Update: per comment below, verified FlowItem class and methods already exist. Updating this request for documentation of these items.
Original request:
Currently there is no FlowItem class and methods in TSC. Can we get that on the backlog (similar to DatasourceItem and WorkbookItem)? For now we have done a workaround using metadata api integration, but the code implementation was lengthy.

Cheers!

They do exist (and have for a little while), see: https://github.com/tableau/server-client-python/blob/master/tableauserverclient/models/flow_item.py for the item class, and there are flow endpoints as well

Oooh! Thanks! Can I update my request to get this into the documentation? 😄

We'll use this issue to track adding the docs to match the code changes from #494
