[smkhalsa]

moving this from gql-dart/ferry#7

Any update regarding this?

There is no active work going on related to this. Contributions are very welcome.

The plan is to adopt https://github.com/zino-app/graphql-flutter/blob/master/packages/graphql/lib/src/link/web_socket/link_web_socket.dart

If graphql-flutter switches to gql_link, I imagine many others will be looking for a WebSocket link.

[klavs]

Yes, that would indeed be a prerequisite. See also #57

Thanks to @iscriptology this is now implemented and published as https://pub.dev/packages/gql_websocket_link

Note that it's an alpha release.
