How to Create a Horizontal Line in Flutter

Sometimes, you may need to add a horizontal line in your UI. This divider line can help you to separate other components visually. In this flutter tutorial, let’s see how to show a horizontal divider line in Flutter.

There are multiple ways to create a horizontal line. Here, we are using the Divider class. A divider is a thin horizontal line with padding on either side. There are properties such as color, indent, endIndent, height, etc to customize the horizontal line.

const Divider(
            color: Colors.black,
            height: 25,
            thickness: 2,
            indent: 5,
            endIndent: 5,
          ),

Following is the complete example where two Expanded widgets are separated by a horizontal line provided by the Divider class.

import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

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

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(),
    );
  }
}

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

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text(
          'Flutter horizontal line tutorial',
        ),
      ),
      body: Column(
        children: <Widget>[
          Expanded(
            child: Container(
              color: Colors.red,
            ),
          ),
          const Divider(
            color: Colors.black,
            height: 25,
            thickness: 2,
            indent: 5,
            endIndent: 5,
          ),
          Expanded(
            child: Container(
              color: Colors.blue,
            ),
          ),
        ],
      ),
    );
  }
}

Following is the output of the flutter example.
