If you’re looking for a comprehensive guide to the Flutter Listview class, you’ve come to the right place. In this article, we’ll explore the fundamentals of the Listview class and its various features, including horizontal Listview, Listview with section headers, Listview with sticky headers, Listview with pull to refresh, Listview with infinite scroll, Listview with custom header and footer, and empty state in Listview. We’ll also provide concrete code snippets with documentation to help you get the most out of the Listview.

What Is Listview in Flutter?

Listview is a scrollable, linear list of widgets. It’s a powerful tool for displaying large amounts of data in a concise, organized manner. The Listview widget is used to create lists in Flutter. It’s important to note that Listview is not a replacement for the List widget. While Listview is used for scrolling lists of data, List is used for static lists of data.

How to Use Listview in Flutter?

To use Listview in Flutter, you need to import the Listview class from the material library. You can do this with the following code:

import 'package:flutter/material.dart';

Once you’ve imported the Listview class, you can start building your list. To create a simple Listview, you can use the following code:

ListView(
  children: <Widget>[
    Text('Item 1'),
    Text('Item 2'),
    Text('Item 3'),
  ],
),

Horizontal Listview in Flutter

If you want to create a horizontal Listview instead of a vertical one, you can use the following code:

ListView(
  scrollDirection: Axis.horizontal,
  children: <Widget>[
    Text('Item 1'),
    Text('Item 2'),
    Text('Item 3'),
  ],
),

Listview with Section Headers in Flutter

If you’re looking to add section headers to your Listview, you can use the following code:

ListView.separated(
  itemCount: 10,
  itemBuilder: (context, index) {
    return ListTile(
      title: Text('Item $index'),
    );
  },
  separatorBuilder: (context, index) {
    return Divider(
      color: Colors.black,
    );
  },
),

Listview with Sticky Headers in Flutter

To create a sticky header Listview, you need to use a SliverList and a SliverStickyHeader widget. You can do this with the following code:

SliverList(
  delegate: SliverChildListDelegate([
    SliverStickyHeader(
      header: Container(
        color: Colors.black,
        padding: EdgeInsets.symmetric(vertical: 8.0, horizontal: 16.0),
        child: Text('Header'),
      ),
      sliver: SliverList(
        delegate: SliverChildListDelegate([
          Text('Item 1'),
          Text('Item 2'),
          Text('Item 3'),
        ]),
      ),
    ),
  ]),
),

Listview with Pull to Refresh in Flutter

If you want to add pull to refresh functionality to your Listview, you can use the RefreshIndicator widget. You can do this with the following code:

RefreshIndicator(
  onRefresh: () async {
    // Refresh your data here
  },
  child: ListView(
    children: <Widget>[
      Text('Item 1'),
      Text('Item 2'),
      Text('Item 3'),
    ],
  ),
),

Listview with Infinite Scroll in Flutter

If you want to add infinite scroll functionality to your Listview, you can use the ListView.builder widget. You can do this with the following code:

ListView.builder(
  itemCount: 10,
  itemBuilder: (context, index) {
    return ListTile(
      title: Text('Item $index'),
    );
  },
),

Listview with Custom Header & Footer in Flutter

If you want to add custom header and footer widgets to your Listview, you can use the ListView.builder widget. You can do this with the following code:

ListView.builder(
  itemCount: 10,
  itemBuilder: (context, index) {
    return ListTile(
      title: Text('Item $index'),
    );
  },
  // Add a custom header
  header: Container(
    color: Colors.black,
    padding: EdgeInsets.symmetric(vertical: 8.0, horizontal: 16.0),
    child: Text('Header'),
  ),
  // Add a custom footer
  footer: Container(
    color: Colors.black,
    padding: EdgeInsets.symmetric(vertical: 8.0, horizontal: 16.0),
    child: Text('Footer'),
  ),
),

Empty State in Listview in Flutter

If you want to add an empty state to your Listview, you can use the ListView.builder widget. You can do this with the following code:

ListView.builder(
  itemCount: 10,
  itemBuilder: (context, index) {
    if (index == 0) {
      return Container(
        color: Colors.black,
        padding: EdgeInsets.symmetric(vertical: 8.0, horizontal: 16.0),
        child: Text('Empty State'),
      );
    }
    return ListTile(
      title: Text('Item $index'),
    );
  },
),
