How can I creat endless scrolling in Xamarin - xamarin

Question

So I have this app where im trying to creat circular scrolling, for exemple while scrolling down i get :
... - Item 4 - Item 5 - Item 1 - Item 2 - Item 3 - Item 4 - Item 5 - Item 1 - Item 2 - Item 3 - ...
this a picture of what Im trying
So the scrolling will be endless because the same items will be repeated. Can anyone help me with that ?

you could refer to Infinite Scrolling
here is a simple sample :
install Nuget Xamarin.Forms.Extended.InfiniteScrolling
the page's axml :
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:scroll="clr-namespace:Xamarin.Forms.Extended;assembly=Xamarin.Forms.Extended.InfiniteScrolling"
x:Class="InfiniteScrollingApp.SimplePage">
<!-- a normal list view -->
<ListView CachingStrategy="RecycleElement" ItemsSource="{Binding Items}">
<!-- the behavior that will enable infinite scrolling -->
<ListView.Behaviors>
<scroll:InfiniteScrollBehavior />
</ListView.Behaviors>
<!-- the row definition -->
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<Label Text="{Binding Name}" />
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
the ViewModel :
public class MyViewModel
{
public InfiniteScrollCollection<MyData> Items { get; set; }
public MyViewModel()
{
var items = new InfiniteScrollCollection<MyData>();
MyData data1 = new MyData() { Name = "1" };
MyData data2 = new MyData() { Name = "2" };
MyData data3 = new MyData() { Name = "3" };
MyData data4 = new MyData() { Name = "4" };
MyData data5 = new MyData() { Name = "5" };
MyData data6 = new MyData() { Name = "6" };
MyData data7 = new MyData() { Name = "7" };
MyData data8 = new MyData() { Name = "8" };
MyData data9 = new MyData() { Name = "9" };
MyData data10 = new MyData() { Name = "10" };
MyData data11 = new MyData() { Name = "11" };
MyData data12 = new MyData() { Name = "12" };
items.Add(data1);
items.Add(data2);
items.Add(data3);
items.Add(data4);
items.Add(data5);
items.Add(data6);
items.Add(data7);
items.Add(data8);
items.Add(data9);
items.Add(data10);
items.Add(data11);
items.Add(data12);
Items = items;
//var dataSource = new MyDataSource();
Items = new InfiniteScrollCollection<MyData>
{
OnLoadMore = async () =>
{
return items;
}
};
// load the initial data
Items.LoadMoreAsync();
}
}
the model :
public class MyData
{
public string Name { set; get; }
}
the effect is below :
