final myList = ['Apples','Cheese','Bread','Milk'].forListbox().toList();

// Create the listbox widget
return Listbox(
items: myList,
itemTemplate: (context, eventManager, index, item, onSelect) {
// Define the template used for each listitem
return SimpleListboxItem(
key: Key('$index'), // Key is required for reordering
item: item,
label: item.data,
eventManager: eventManager,
onSelect: onSelect,

onSelect: (itemsSelected) {
// React to items selected
// Note: (value of isSelected is not set automatically by Listbox,
// due to not knowing how your state is handled)

item.isSelected = itemsSelected.contains(item);
}
