PreviewRegistryBuilder class
Generates a $previews registry for a library that declares a
@PreviewRegistry() variable, by scanning every library under the package's
lib/ for @Preview / @MultiPreview targets.
The output is a standalone library (not a part) so it can declare the
prefixed imports needed to reference previews defined across many files. The
trigger library imports it and assigns the generated symbol, whose name
mirrors the annotated variable (myPreviews → $myPreviews):
import 'previews.preview_registry.g.dart';
@PreviewRegistry()
const myPreviews = $myPreviews;
