I'm creating a travel app in flutter for people to create trips and share with other users that can modify its contents. I'm currently using firebase authentication so each user has an unique id. I'm having trouble understanding what concept I should use to share trip1 with user2. I found out documentReferences allow you to share the specific path of the trip with other users but it doesn't necessarily add the trip to user2 so they can see it on their dashboard. Is documentReferences the correct way to share data with other users?
