removeDocument method
Remove a single document by ID. No-op if the ID is absent.
Call after initialize. Before the store is initialized, behavior is
backend-specific (the SQLite store throws a StateError; the Qdrant
store logs and no-ops) — don't rely on either.
Implementation
Future<void> removeDocument({required String id}) =>
FlutterGemmaPlugin.instance.removeDocument(id: id);
