i'm looking for a way to show what portal item are in a group.
i have found the PortalGroup object https://developers.arcgis.com/flutter/api-reference/reference/arcgis_maps/PortalGroup-class.html, but can't see a way to use this to find items in a group.
if there are no way to do it in the sdk i think i can use the rest api https://developers.arcgis.com/rest/users-groups-and-items/groups/. But would be easier if i could let the maps sdk for flutter handle it.
