Error found in note_form_page.dart and error_note_card_widget.dart.

A possible fix is to change bodyText2 to body2.

Hello, this project was built on the beta/dev versions of Flutter. A new stable version should come out soon and this "error" will be gone, as there are some name changes in the new version.
