Basically, what it does is:

• Use dart's http package to send post/get requests, encapsulated in NetworkUtil class.
• RestDataSource do the login() and return a User instance.

• LoginScreenPresenter defines an interface for LoginScreen view and a presenter that incorporates all business logic specific to login screen itself.

• The view LoginScreen contains the login form.
