I have a scrollable ListView where the number of items can change dynamically. Whenever a new item is added to the end of the list, I would like to programmatically scroll the ListView to the end. (e.g., something like a chat message list where new messages can be added at the end)
My guess is that I would need to create a ScrollController in my State object and pass it manually to the ListView constructor, so I can later call animateTo() / jumpTo() method on the controller. However, since I cannot easily determine the maximum scroll offset, it seems impossible to simply perform a scrollToEnd() type of operation (whereas I can easily pass 0.0 to make it scroll to the initial position).
Is there an easy way to achieve this?
Using reverse: true is not a perfect solution for me, because I would like the items to be aligned at the top when there are only a small number of items that fit within the ListView viewport.
