SubcomposeLayout

A layout whose children are produced by calling content with the current SubcomposeScope. The closure is invoked during reconciliation and returns a list of (slot_id, view) pairs. Each slot id is a stable identity used to reconcile the returned view across frames. This is the building block for BoxWithConstraints and other constraints-driven layouts.

Note: any Modifier::key set on a returned view is overwritten by its slot id so the slot’s identity is stable across frames.

Fields

content: Arc<dyn Fn(&SubcomposeScope) -> Vec<(u64, View)>>
