Right now, if I understand correctly the query is a widget so it's building the UI with the result of the query.

Is it possible to run a query outside of a widget and just fet the result ?

For now, you can import the client.dart and call the method execute().
client.execute( query: '<YOUR_QUERY_STRING>', variables: variables, ); which returns Future<Map<String, dynamic>>

We will try to add a more elegant solution in the near future.
