FlexBoxConfig

Represents a configuration for a FlexBox container.

FlexBoxConfig is implemented as a functional interface where the lambda is executed on FlexBoxConfigScope during the layout phase. This means that reading state inside the lambda will only trigger relayout, not recomposition.

Note: Configuration properties are not additive. If a property is assigned multiple times within the configuration block, the last assignment overrides previous values.

Reusable Config

For better performance, define configs as top-level constants:

private val RowWrap = FlexBoxConfig {
    direction = FlexDirection.Row
    wrap = FlexWrap.Wrap
    gap = 8.dp
}
