[FIXED] Focus the bottom of a ListView ? Flutter

Issue

If I add items dynamically to a listView with a listView.builder, how do I keep the bottom of the list focus ? Like if the list is full, and I add an Item, how do I do to make the other go up and focus the last item without deleting anything ?

Solution

Hi you can take help of ScrollController using method jumpTo() or animateTo() like bellow,

First create instance of

ScrollController controller = new ScrollController();

Then after registering it with your listview like bellow example

ListView.builder(
              itemBuilder: (context, index) => ListTile(
                title: Text("Item List"),
              ),
              controller: controller,
              itemCount: 50,
            ),

And finally call jumTo() or animateTo() method when new item added or whenever you want to go at bottom like bellow

controller.jumpTo(controller.position.maxScrollExtent);
