Introduction

In modern Android development, Jetpack Compose has revolutionized how we build user interfaces. One of its standout features is its ability to manage UI state effortlessly. Compose takes a state-driven approach to UI, ensuring that changes in state automatically update the UI.

In this article, we’ll dive into best practices for managing UI state in Jetpack Compose, supported by code examples to get you started.

Understanding State in Jetpack Compose

State represents data that dictates how your UI appears and behaves at any moment. In Compose, state is critical because it follows the Unidirectional Data Flow (UDF) pattern, where state flows from a source (e.g., ViewModel) to composables, and user events flow back to the source.

Why does this matter?
With UDF, you avoid common bugs caused by two-way data binding and keep your UI consistent.

State Management Techniques

There are two primary ways to manage state in Jetpack Compose:

  1. State Hoisting
  2. ViewModel as a State Holder
