Describe the problem

On step 4- "Create structure for a 3-tab app", AppStateModel is used as a type for the Consumer, and appears to be imported from import 'model/app_state_model.dart';, but this does not seem to be a default library, and there is no mention in the guide up to this point that explains what the file is or where it comes from or what it contains.

It appears this is introduced in the next step, but this does not help for users following along.

Expected fix

A simple note that "this will be introduced in the next step" or something to that effect would be really useful to include.

I would like to fix this problem.
