You do have a scaffold, but not above the context of MyHomePage. Your Scaffold is a child of MyHomePage, while doing Scaffold.of(context) is trying to access the closest parent Scaffold. And since you have none, it crash.

You should probably wrap your BottomNavigationBar into a new class. And use that widget's context to do Scaffold.of(context).
