Passing UIState from viewmodel to activity using kotlin sealed classes

Passing UIState from ViewModel to Activity with Kotlin Sealed Classes

This project is used for tutorials on U4Universe Youtube channel.

Introduction

As our android app uses MVVM architecture, often times we need to send Commands to our View(Activity) from ViewModel.

We can do this using kotlin enums but there is a limitation with enums. We cannot pass any custom data to View with enums.

Kotlin provide another solution for this ---> SealedClasses

We'll learn

• Create UIState with Sealed Classes
• Send States from ViewModel to Activity
• Update the View according to Ui States
