Introduction

In this section, we will learn about the NyListView widget.

The NyListView widget is a helpful widget for handling List Views in your Flutter projects.

It works in the same way as the regular ListView widget, but it has some extra features that make it easier to use.

Let's take a look at some code.

Usage

Here's how you can start using the NyListView.

@override
Widget build(BuildContext context) {
return NyListView(child: (BuildContext context, dynamic data) {
    return ListTile(
        title: Text(data['title'])
    );
}, data: () async {
    return [
    {"title": "Clean Room"},
    {"title": "Go to the airport"},
    {"title": "Buy new shoes"},
    {"title": "Go shopping"},
    {"title": "Find my keys"}
    ];
});
}

The NyListView widget requires two parameters:

• child - This is the widget that will be displayed for each item in the list.
• data - This is the data that will be displayed in the list.

Tip: You can use the NyListView.separated widget to add a divider between each item in the list.

Parameters

Here are some important parameters you should know about before using the NyPullToRefresh widget.

Updating the State

You can update the state of a NyListView widget by referencing the stateName parameter.

// e.g.
@override
  Widget build(BuildContext context) {
    return NyListView(
        child: (BuildContext context, dynamic data) {
          return ListTile(title: Text(data['title']));
          }, 
        data: () async {
          return  [
            {"title": "Clean Room"}, 
            {"title": "Go to the airport"}, 
            {"title": "Buy new shoes"}, 
            {"title": "Go shopping"},
          ];
        },
      stateName: "my_list_of_todos",
    );
  }


_updateListView() {
    updateState("my_list_of_todos");
}

This will trigger the State to reboot and load fresh data from the data parameter.
