Neo4j user trying to implement it with GraphQl and use it in a Flutter app

That's the kind of help I was missing :) I posted a link to your answer in my original post for reference.

Another issue I was facing was to install GraphQl on a server hosting the database (Difficulties installing neo4j-graphql on Google cloud server). It was easy on the desktop version, as there was simply a plugin to install, but I couldn't find exactly how to configure it for the server version.
