> **Requires Opt-in** This FlexBox API is experimental and is likely to change or be removed in the future.\nThis API is experimental because it introduces a new category of layout concepts to the Compose Foundation library. \nIt requires a period of user validation to ensure the API surface is intuitive and flexible enough to cover the intended use cases before being stabilized.
