Dividers Between Rows

Part of the Lists and Screens section of Coddy's Flutter journey. Lesson 5 of 33.

Rows that sit right against each other are hard to tell apart. A Divider draws a thin grey line across the list:

ListView(
  children: [
    ListTile(title: Text('Wi-Fi')),
    Divider(),
    ListTile(title: Text('Bluetooth')),
  ],
)

It goes between two rows, so a list of four rows needs three dividers, and none after the last row.

Divider takes a few settings when you want it different: thickness: for the line, color:, and indent: to start it further from the left edge.

Challenge

Easy

The settings list has a line between Wi-Fi and Bluetooth only. Add a Divider between every two rows, so there are three lines and none after Sound.

Try it yourself

import 'package:flutter/material.dart';

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

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Scaffold(
        appBar: AppBar(title: const Text('Settings')),
        body: ListView(
          children: const [
            ListTile(leading: Icon(Icons.wifi), title: Text('Wi-Fi')),
            Divider(),
            ListTile(leading: Icon(Icons.bluetooth), title: Text('Bluetooth')),
            ListTile(leading: Icon(Icons.battery_full), title: Text('Battery')),
            ListTile(leading: Icon(Icons.volume_up), title: Text('Sound')),
          ],
        ),
      ),
    );
  }
}
