Below is an Office 365 Message Center Update:
Updated Feature: Flow integration with SharePoint Online list and libraries
Published On : March 13, 2017
Expires On : April 20, 2017
In our next wave of updates to Flow in SharePoint, we’ve added the capability to build a new Flow directly from a document library. We’re also adding the ability to build Flows in lists and libraries which can be launched on demand, for a single item or document, using a button added to the command bar.

How does this affect me?
The new features provide additional Flow integration directly from the modern command bar in lists and libraries. We'll be gradually rolling this out to First Release customers starting March 20, and completing around the end of April. Then, we’ll begin rolling out to the rest of customers.
