The Optimizely Configured Commerce Mobile SDK relies on GetIt for the service locator. To add a new service, follow these steps:

1. Define your interface with the new methods.
2. Implement your interface.
3. Add your class to the GetIt Service Locator in `lib/core/injection/injection_container.dart`.
4. (Optional) Add your class to the `CoreServiceProvider`: `lib/features/domain/service/interfaces/core_service_provider_interface.dart` and `lib/features/domain/service/core_service_provider.dart`

When added in `injection_container.dart`, you can access your service from anywhere using `CoreServiceProvider` or with `sl<YourInterfaceName>().yourProperty`.
