It's telling you what the problem is. There is no widget called "milk" to route to.

Would be helpful to see "milk.dart". I guess it's where you want to define the next screen.
You need a class called "milk" (personally preferring capital letters for class names) in there which extends either StatelessWidget or StatefulWidget.
