Hey everyone, I am trying to build a Flutter app that will use Neo4j as database. I am new to programming and new to Neo4j. The plugin [graphql\_flutter](https://pub.dev/packages/graphql_flutter) should allow me to communicate with the database through using GraphQL. I created a test app that fetches data from a freely available database and that works, so the code should be good. Here is the code : [graphql\_app/main.dart at master · louisdeveseleer/graphql\_app · GitHub](https://github.com/louisdeveseleer/graphql_app/blob/master/main.dart) Here are the steps I followed on the Neo4j side: -Create a local database on Neo4j desktop -Install the GraphQL plugin -Remove authentication for this database (to make things easier to start with) with the setting `dbms.security.auth_enabled=false` -Populate this database with the sample movie data `:play movie` -Automatically generate the graphql schema (`CALL graphql.idl(null);`) -Launch GraphiQL and connect to [http://localhost:7474/graphql/](http://localhost:7474/graphql/) -Test a query: ```auto {Movie{ title } } ``` which returned a list of movies, so everything seems to be set up right. Here is the issue: When in the Flutter app I replace the line for the HttpLink `uri: 'https://countries.trevorblades.com/'` (used for testing) by `uri: 'http://localhost:7474/graphql/'` then i get this error on the app screen: **`ClientException: Failed to connect to http://localhost:7474/graphql/:`** And since it is working with GraphiQL, I don't know what to do here. ---

Hi Louis, Some questions: • Which version of neo4j are you using? • Were you able to connect at some point with some other code? • Did you test the connection directly via neo4j desktop | browser? ---

Hi! - Neo4j 4.0.1 - It's the first time I am trying to connect to my local database with a code - I can access the database by going into a browser and typing [http://localhost:7474/browser/](http://localhost:7474/browser/) (or through the desktop) ---

I never used the flutter connection, but have you tried the bolt connection? ---

How can I do that? Typing bolt://localhost:7687 in the browser does not work. ---

I am now trying Google cloud platform to host and access my database through GraphQL. The hosting of the database is up and running but I struggle to find exactly how to install a graphql plugin on it. ---

Were you able to figure anything out? I'm about to try Flutter - Neo4j too ---

No. I switched to Firebase and everything is much easier to setup and manage. I still like the idea of a graph database, but the implementation is just too technically difficult to be worth it in my case. ---
