Xamarin forms, how to add new item to listview dynamically when the button is clicked

Hello guys

I couldn't find a solution on the internet of how to add a new item to listview dynamically in Xamarin forms project when the button is clicked. The only things I got on the internet is how to delete an item from listview dynamically.

So please how I can write a code in Xamarin forms to add a new item to the listview dynamically when the button is clicked?
