I have collections Routes and Places of Interests (POIs). The collection Places of Interests hold the LatLng information and are separate documents. In Routes collections, I have this linked as a List<Doc References (PlacesofInterest)>. The Routes list appear on Home page in list view. It leads to the Map page after couple of bottom sheet are displayed. On map, I currently have all the Places of Interest visible. What I want is when a user clicks on a particular route on home and triggers the bottomsheet, and leads to the Map page, the Map page needs to display only the markers based on the List<Doc References (PlacesofInterest)>. How can I implement this?
