get_it seems to be closing http Client connection!

After switching to get_it (get_it: ^4.0.2), my flutter app starts failing with this error:

flutter: SchedulerBloc LoadUserReservations err ===>>> NoSuchMethodError: The method 'openUrl' was called on null.
Receiver: null
Tried calling: openUrl("GET", Instance of '_Uri')
SchedulerBloc LoadUserReservations stack ===>>> #0      Object.noSuchMethod (dart:core-patch/object_patch.dart:51:5)
#1      IOClient.send (package:http/src/io_client.dart:31:37)
#2      BaseClient._sendUnstreamed (package:http/src/base_client.dart:176:38)
#3      BaseClient.get (package:http/src/base_client.dart:35:7)
<... trimmed ...>

NOTE that one call goes through the HTTP client, after that calls through the client error out with the above.

Here is what my setup looks like (trimmed for brevity):

...
import 'package:http/http.dart' as http;

// "service locator" shortcut.
final sl = GetIt.instance;

Future<void> initServiceLocators() async {
  // Facility chain
  sl.registerFactory(() => FacilityBloc(sl()));
  sl.registerLazySingleton(() => FacilityRepository(sl()));
  sl.registerLazySingleton(() => FacilityAPIClient(sl())); // need http.Client()

  // Scheduler chain
  sl.registerFactory(() => SchedulerBloc(sl()));
  sl.registerLazySingleton(() => SchedulerRepository(sl()));
  sl.registerLazySingleton(() => SchedulerApiClient(sl())); // need http.Client()

  // Auth chain <... trimmed ...>

  // Register system services
  final SharedPreferences sharedPreferences = await SharedPreferences.getInstance();
  sl.registerLazySingleton(() => sharedPreferences);
  sl.registerLazySingleton(() => http.Client());
}

Let me know if I am doing anything wrong.

Sorry! My bad!
I started setting breakpoints and noticed a close() call in my SchedulerApiClient - this was being called by the hot reload process.
Removed it.
get_it works as expected.
