keyed_form_core 0.2.0

Shared vocabulary for the keyed_form family: FieldRef / StrictFieldRef / VariantFieldRef field references over keyed_lens optics, DelegatingFieldRef, FieldErrors, and the @keyedSchema annotation.

keyed_form_core

Shared vocabulary for the keyed_form family. It sits on keyed_lens and below keyed_form_schema / keyed_form — you normally reach it transitively, not by importing it directly.

What it gives the form layers

Name	Is	For
FieldRef<R, V>	extension type wrapping AffineLens<R, V>	a typed handle to a field that may not resolve (removed row, null sub-struct, wrong union variant)
StrictFieldRef<R, V>	extension type wrapping Lens<R, V>	a field that always resolves — get is non-null
VariantFieldRef<S, V>	extension type wrapping Prism<S, V>	narrowing to one variant of a sum type
DelegatingFieldRef<R, V>	extends AffineLens	base the generated <X>FieldRefs wrappers extend — holds an inner ref and forwards key/find/set
.whenPresent() / .narrow() / .at()	extensions on FieldRef	refine a nullable field · narrow a union · descend into a list row by id
FieldErrors<E>	FieldKey-keyed sidecar map	validation messages (or any per-field E)
@keyedSchema / KeyedSchema	annotation	marks a library for keyed_form_gen

The raw optic names (Lens / AffineLens / Prism / ListItemLens) are not re-exported here — these extension types are form-layer wrappers, not typedef aliases. Import package:keyed_lens/keyed_lens.dart directly only for standalone optics work.
