How to identify when end of the list is reached on scrolling in .NET MAUI ListView (SfListView) ?

public class ListViewBehavior : Behavior<SfListView>
{
    SfListView ListView;
    VisualContainer VisualContainer;
    bool isAlertShown = false;
    int totalItems = 0;
 
    protected override void OnAttachedTo(SfListView bindable)
    {
        ListView = bindable;
 
        ListView.Loaded += ListView_Loaded;
        VisualContainer = ListView.GetVisualContainer();
        VisualContainer.ScrollRows.Changed += ScrollRows_Changed;
 
        base.OnAttachedTo(bindable);
    }
 
    private void ListView_Loaded(object sender, EventArgs e)
    {
        //To include header if used
        var header = (ListView.HeaderTemplate != null && !ListView.IsStickyHeader) ? 1 : 0;
        //To include footer if used
        var footer = (ListView.FooterTemplate != null && !ListView.IsStickyFooter) ? 1 : 0;
        totalItems = ListView.DataSource.DisplayItems.Count + header + footer;
    }
 
    private void ScrollRows_Changed(object sender, ScrollChangedEventArgs e)
    {
        var lastIndex = VisualContainer.ScrollRows.LastBodyVisibleLineIndex;
 
        if (lastIndex != -1 && (lastIndex == totalItems - 1))
        {
            if (!isAlertShown)
            {
                App.Current.MainPage.DisplayAlert("Alert", "End of list reached...", "Ok");
                isAlertShown = true;
            }
        }
        else isAlertShown = false;
    }
}
