구글지도 - 플랫폼뷰 관련 에러

안녕하세요 강사님, 구글지도 사용해보기 수업을 듣는데 지도가 나타나지 않아 질문드립니다.
PlatformView, registerViewFactory가 호출되었는지 확인하라는 메세지로 파악했으나 해결 방법을 찾지 못하고 있습니다.

에러 메세지는 아래와 같습니다.

[VERBOSE-2:dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(unregistered_view_type, A UIKitView widget is trying to create a PlatformView with an unregistered type: < plugins.flutter.io/google_maps >, If you are the author of the PlatformView, make sure registerViewFactory is invoked.

See: https://docs.flutter.dev/development/platform-integration/platform-views#on-the-platform-side-1 for more details.

If you are not the author of the PlatformView, make sure to call GeneratedPluginRegistrant.register., null)
