Twitch with supplied data

I came across the post that provided the data that the Twitch API would return. I’m using that in my project but I dont see any field that indicates whether the user is streaming or not (online or offline). How do we make that determination?

Yes, I saw all that. In the sample application that we are reverse engineering, there were 2 users showing as offline but they both showed icons. In the case where stream = null, there is no icon element so that threw me off. I guess I’ll just force a default icon along with the user name and an “offline” indication in this case. Thanks.
