## AI overview

This tutorial introduces FlexBox, a new Jetpack Compose layout system inspired by CSS Flexbox. It explains how FlexBox arranges children dynamically and covers FlexBoxConfig parameters for direction, wrapping, alignment, spacing, and item distribution, along with Modifier.flex controls and code samples.

## Source excerpt

Header image Jetpack Compose continues to evolve, and with the introduction of the new FlexBox layout, we finally have a powerful, flexible way to design adaptive UIs -- inspired by the CSS Flexbox model. https://developer.android.com/develop/ui/compose/layouts/adaptive/flexbox If you've ever used Row, Column, or FlowRowYou'll feel right at home. FlexBox acts as a superset, combining their capabilities while providing granular control over alignment, wrapping, and item distribution. Until now, we had to choose between rigid layouts (Row/Column) or more dynamic ones (FlowRow/FlowColumn). FlexBox merges the best of both worlds -- flexibility and simplicity. What Is FlexBox? Composable brings the concept of flexible layouts from the web into Jetpack Compose. Arranges its children dynamically, allowing them to grow, shrink, or wrap based on available space and configuration.

Key parameters: direction: Controls the main axis (Row, Column). wrap: Determines if items flow onto new lines. Here we have 3 options: Wrap, NoWrap, WrapReverse justifyContent: Distributes space along the main axis(start, end, etc). alignItems: Defines how items align on the cross-axis(start, end, etc). alignContent: Controls how multiple lines are distributed along the cross-axis. This applies only when the wrap is FlexWrap.Wrap or FlexWr
