One running npm run test:flow I got a little more information.

Cannot determine the type of props [1] because it contains a spread of inexact object type [2]. Being inexact, object
type [2] might be missing the types of some properties that are being copied. Perhaps you could make it exact?
(inexact-spread)

Appears four times. Full output to follow.

interesting, I have no idea of how those flow types work. I will try an npm setup myself later today and see if I reproduce it.

[claytron5000]

It looks like the flow document is automatically generated. http://github.com/joarwilk/flowgen. It also looks like the ...getItemProps is the offending spread. There's an issue around spread in the flow repo: facebook/flow#2405.

I'm really not sure if this will require a work-around, or if there's a way I can bypass this step and still contribute. Remember, the goal for me here is contribute back to the project, so whatever aids with that in mind.

[silviuaavram]

I updated our dependencies recently and running setup should work fine. Maybe do npm reinstall, cache clean, remove package lock if you have any, figure out what the flow errors mean. I personally don't have any knowledge of flow, so cannot assist you there.
