Jetpack Compose is an open-source reactive user interface (UI) framework developed by Google for cross-platform software development in Kotlin. The first preview was announced in May 2019, and the framework was made ready for production in July 2021.

In Compose, a user interface is defined using functions that have been annotated with the @Composable annotation, which are known as composable functions and define the screen's state. Jetpack Compose uses a Kotlin compiler plugin to transform composable functions into UI elements. For example, the following code defines a simple UI element:

@Composable
fun Greeting(name: String) {
    Text(text = "Hello $name")
}
