问题 I've heard that you have to disable the lazy loading feature of EF in web applications. (ASP.NET). Here and here, for instance.

问题 I would like to have a ListView in flutter which provides lazy loading in both directions (up, down). Example: There are 60000 items in the backend database which can be theoretically displayed. First I want to display the items 100..120 From these indices I want to be able to scroll up and down while lazy loading the new items Things to consider: The top and bottom edge (current index < 0 or > 60000) should be bouncing if reached while scrolling What I've tried: Most of the approaches in
