Is There a Difference Between a Widget and an Elements Tree?

Frey: I don't think there's a big a push in flutter about how and why everything works the way it does. He went over so many different topics at one over another, but all of them were very interesting. Frey what i'm talking about is basically the two types of trees, the widget tree and then the element tree. The biggest thing is when you have form data with to link that up, every time the widge treeis rebuilt, you've got to use key so the element tree c match up.
