Many properties created as dynamic, whilst definition exists in Swagger

[HEBOS]

Describe the bug
Many properties created as dynamic, despite type being described in swagger.json
An example is BlobFile model, with a few properties created as dynamic:

To Reproduce
Generate clients using supplied swagger definition, and try creating create BlobFile object using:

final blobFile = BlobFile(
          documentType: DocumentType.cashdocument,
          date: DateTime.now(),
          description: null,
          name: 'test',
          blobFormatType: BlobFormatType.pdf,
          blobFileType: BlobFileType.document,
          blobFileId: 'test',
          lastChange: (
            userId: 'test',
            date: DateTime.now(),
          ),
          owner: UserOwned(
            userId: 'test',
            name: 'test',
          ).toJson(),
          team: TeamOwned(
            teamId: 'test',
            name: 'test',
          ),
        );

Expected behavior
To get properties having strong types.
