NyListView<T> class

The NyListView widget is a wrapper for the ListView widget. It provides a simple way to display a list of items. Example:

NyListView(
 data: () async => [1,2,3,4,5],
 child: (context, data) {
  return Text(data.toString());
 })

The above example will display a list of numbers. The data is fetched from the data function. The child is the widget that will be displayed for each item in the list.
