How to animate the items appearing in .NET MAUI ListView (SfListView)?

The .NET MAUI ListView allows you to animate items as they come into view by overriding the OnItemAppearing method of ListViewItem. This method is raised when an item appears in the view, allowing for animation customization.

This can be achieved by extending the ItemsGenerator class, applying animation for the listview items using the OnItemAppearing method and aborting animation for the collapsed item using the PropertyChanged event.

public class Behaviours: Behavior<SfListView>
{
   private SfListView listView;

   protected override void OnAttachedTo(BindableObject bindable)
   {

      listView = bindable as SfListView;

      listView.ItemsGenerator = new ItemGeneratorExt(listView);

      base.OnAttachedTo(bindable);
   }
}

Extending the ItemsGenerator class:

public class ItemGeneratorExt: ItemsGenerator
{
   public SfListView ListView { get; set; }

   public ItemGeneratorExt(SfListView listview): base(listview)
   {
      ListView = listview;
   }

   protected override ListViewItem OnCreateListViewItem(int itemIndex, ItemType type, object data = null)
   {

      if (type == ItemType.Record)

         return new ListViewItemExt(ListView);

      return base.OnCreateListViewItem(itemIndex, type, data);
   }
}

Customize ListViewItem to apply animations when an item appears.

public class ListViewItemExt: ListViewItem
{

   private SfListView _listView;

        

   public ListViewItemExt(SfListView listView)
   {

      _listView = listView;
   }

   protected override void OnItemAppearing()
   {

      this.Opacity = 0;

      this.FadeTo(1, 400, Easing.SinInOut);              

      base.OnItemAppearing();
   }

}
