A walkthrough on how to implement Jetpack's paging library 3 in a real-world application. Using pagination is a very common practice in many apps, and Jetpack's paging library can help reduce the burden by a lot. But most of the guides out there are focused on the most simple yet not so common use of it. In my talk, I want to show how we used it in viz.ai in an app that requires different filters/tabs, synching server with local cache (using room), and responding to user actions. Plus, I'm going to give my review of this library and what I think its pros and cons are.
