Create a horizontal list

You might want to create a list that scrolls horizontally rather than vertically. The ListView widget supports horizontal lists.

Use the standard ListView constructor, passing in a horizontal scrollDirection, which overrides the default vertical direction.

dart
ListView(
  // This next line does the trick.
  scrollDirection: Axis.horizontal,
  children: <Widget>[
    Container(width: 160, color: Colors.red),
    Container(width: 160, color: Colors.blue),
    Container(width: 160, color: Colors.green),
    Container(width: 160, color: Colors.yellow),
    Container(width: 160, color: Colors.orange),
  ],
),

#
import 'package:flutter/material.dart';

void main() => runApp(const MyApp());

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    const title = 'Horizontal List';

    return MaterialApp(
      title: title,
      home: Scaffold(
        appBar: AppBar(title: const Text(title)),
        body: Container(
          margin: const EdgeInsets.symmetric(vertical: 20),
          height: 200,
          child: ListView(
            // This next line does the trick.
            scrollDirection: Axis.horizontal,
            children: <Widget>[
              Container(width: 160, color: Colors.red),
              Container(width: 160, color: Colors.blue),
              Container(width: 160, color: Colors.green),
              Container(width: 160, color: Colors.yellow),
              Container(width: 160, color: Colors.orange),
            ],
          ),
        ),
      ),
    );
  }
