enableInjection method
Allows the DevTools panel to push values into the wrapped subject.
parse converts the raw text from the panel's input into the subject's
value type; returning null causes the panel to surface a parse error
without changing the subject. No-op in release builds.
Implementation
TrackedSubject<T, S> enableInjection({
required T? Function(String raw) parse,
}) {
final id = identifier;
if (id == null) return this;
getIt.get<RegistryService>().enableInjection<T>(_subject, parse, id);
return this;
}
