List View in Flutter
ListView In Flutter
ListView is a type of widget in Flutter used to display a list of items in a scrollable column or row. It’s similar to how you scroll through your contacts on a phone or through posts on a social media app. ListView is flexible and can be used for simple lists as well as more complex ones with different types of items.
Example 1: To Do List App
In this example below, you will learn how to create a simple to-do list app using ListView. Here’s how you can make a list with titles and subtitles for each task.
ListView(
children: [
ListTile(
title: Text('Go to Gym'),
subtitle: Text('Go to Gym at 6:00 AM'),
),
ListTile(
title: Text('Go to College'),
subtitle: Text('Go to College at 8:00 AM'),
),
ListTile(
title: Text('Go to Office'),
subtitle: Text('Go to Office at 11:00 AM'),
),
// Add more ListTiles as needed
],
)
Note: ListTiles are a convenient way to create lists of items. They provide a leading icon, a title, and a subtitle. You can also add trailing icons if needed.
Example 2: Contact List App
In this example below, you will learn how to create a simple contact list using ListView with icons, names, numbers, and a call icon.
ListView(
children: [
ListTile(
leading: Icon(Icons.person),
title: Text('John Doe'),
subtitle: Text('555-555-5555'),
trailing: Icon(Icons.call),
),
ListTile(
leading: Icon(Icons.person),
title: Text('Jane Doe'),
subtitle: Text('555-555-5555'),
trailing: Icon(Icons.call),
),
ListTile(
leading: Icon(Icons.person),
title: Text('John Smith'),
subtitle: Text('555-555-5555'),
trailing: Icon(Icons.call),
),
],
)
Example 3: Image Gallery App
In this example below, you will learn how to create a photo gallery app using ListView. You can change the scroll direction to horizontal to create a horizontal photo gallery.
ListView(
// try changing to `scrollDirection: Axis.horizontal` to see horizontal list
scrollDirection: Axis.horizontal,
children: [
Image.network('https://picsum.photos/250?image=9'),
Image.network('https://picsum.photos/250?image=10'),
Image.network('https://picsum.photos/250?image=11'),
Image.network('https://picsum.photos/250?image=12'),
Image.network('https://picsum.photos/250?image=13'),
Image.network('https://picsum.photos/250?image=14'),
Image.network('https://picsum.photos/250?image=15'),
],
)
Example 4: Reverse List
In this example below, you will learn how to reverse a list using ListView. You can use the reverse property to reverse the order of the list.
ListView(
reverse: true,
children: [
ListTile(
title: Text('Go to Gym'),
subtitle: Text('Go to Gym at 6:00 AM'),
),
ListTile(
title: Text('Go to College'),
subtitle: Text('Go to College at 8:00 AM'),
),
ListTile(
title: Text('Go to Office'),
subtitle: Text('Go to Office at 11:00 AM'),
),
// Add more ListTiles as needed
],
)
