When you write a Compose UI component, the Compose compiler uses the Kotlin compiler to generate a bytecode representation of your code. The compiler then analyzes this bytecode and generates a new set of bytecode that represents the Android Views that make up your UI.
Recomposition is the process of updating a Compose UI component's UI when its state changes. When a component's state changes, it needs to be recomposed to reflect the new state.

In this article, we looked at the Compose compiler, runtime, composition local, and recomposition. We explored how these components work together to provide a seamless UI experience.
Jetpack Compose is a modern UI framework for building Android apps. It simplifies the process of building user interfaces and reduces the amount of boilerplate code required. But have you ever wondered what happens under the hood? In this article, we'll take a deep dive into the internals of Jetpack Compose and explore how it works. When you write a Compose UI component, the
The Compose runtime is responsible for managing the lifecycle of Compose UI components. It's what allows your Compose UI components to be recreated, updated, and destroyed as needed.
The Compose runtime uses a mechanism called "snapshot flow" to manage recomposition. Snapshot flow is a way of tracking changes to a component's state and updating the UI accordingly. When a component's state changes, it needs to
Jetpack Compose is a powerful and flexible UI framework that simplifies the process of building Android apps. By understanding how it works internally, you can write more efficient and effective Compose UI code.

The first step in understanding Jetpack Compose internals is to look at the Compose compiler. The Compose compiler is a plugin that runs on top of the Kotlin compiler. Its job is to transform Compose UI code into Android Views.
The composition local is based on a concept called "composition scope". A composition scope is a set of components that are related to each other. When a component is composed, it's added to a composition scope. The composition local allows components to access information about their composition scope.
