Flow variables in R

Mali

I checked the R functions here : https://doc.dataiku.com/dss/api/11/R/dataiku/reference/ and it has only dkuFlowVariable where we need to specify the name of the variable. I was wondering if we could get a list of all flow variables in the newer versions of Dataiku. In an earlier version we used to use 'fromJSON(Sys.getenv("DKUFLOW_VARIABLES"))' but that no longer works. Any inputs on this would be appreciated. Thanks!
