// Handle the selection here
},
itemBuilder: (BuildContext context) {
// Define the menu items in a function
return <PopupMenuEntry<T>>[
// Add PopupMenuItem or PopupMenuItemBuilder entries here
PopupMenuItem<T>(

This allows you to display a popup menu when the user taps a specific area of the ListView. In this article, we are going to create a ListView and apply the Options menu to it.
