I am new to flutter and have successfully gotten it installed and working on one machine, but when working on this one I am having some issues. It is a fresh install of android studio, flutter, and gradle. The machine is running an updated Windows 10.
The Flutter doctor statement returns an error while retrieving device properties.

When trying to run the flutter app on an emulated android instance or a real device I get the same error:
Error retrieving device properties for ro.product.cpu.abi:

Another mistake possible is that for a physical device you need to have the file transfer mode enabled (not charging) as well as debugging enabled.
