Jetpack Compose provides a number of APIs for managing state. The most common way to manage state is to use the and mutableStateOf APIs.
The API allows you to store a value in the composition context. The mutableStateOf API allows you to create a mutable state object that can be updated.
The layout system in Jetpack Compose is responsible for measuring and laying out the UI. It's based on a and layout phase.
When the state of the composition changes, the recomposer schedules a . During recomposition, the framework re-executes the composable functions to produce a new composition. The recomposer then updates the UI to reflect the changes.
For those who want to dive deeper into the internals of Jetpack Compose, we've prepared a PDF guide that covers the topics discussed in this blog post.
