In our app, we follow the MVP pattern, separating the internal data model, from a passive view through a presenter that handles the logic of our application and acts as the conduit between the model and the view. The v
In the project, the code is structured by feature. In IntelliJ IDEA project navigator, your can view the project structure
view: This is where all the view logic resides. For example, the
FlightSearchControlleris responsible for the view where one searches for flights.
Presenters: Despite the name, files labelled as

Views get their presenters via Dependency Injection, as per standard MVP architecture.

Throughout this tutorial, we will walkthrough the code in the various presenters to showcase different features of the Couchbase Lite 2.0 API:
