primitives library

Behavioural building blocks that are not catalogued components.

The main flutter_flowin.dart barrel is the design system's catalogued surface: every widget it exports is expected to have a look of its own and a card in the showcase. The widgets here are a tier below that — shared primitives with behaviour but no visual identity, consumed by the catalogued components and available to consumers building their own — so they live behind this separate entry point instead of earning exclusion entries in the catalogue sweep.

Classes

FlowinFadePage

Cross-fades one page in place against a scrolling position.

FlowinKeepAlivePage

Keeps a lazily-built page alive when its scroller would otherwise dispose it.
