Dart - add a subtitle in flutter code

Adding a subtitle in Flutter can be done using various widgets depending on where you want the subtitle to appear. Here are some common approaches:

1. Using ListTile

If you want to add a subtitle to a ListTile, you can do so directly using the subtitle property.

Example:

import 'package:flutter/material.dart'; void main() { runApp(MyApp()); } class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( home: Scaffold( appBar: AppBar(title: Text('Subtitle Example')), body: ListView( children: <Widget>[ ListTile( leading: Icon(Icons.info), title: Text('Main Title'), subtitle: Text('This is the subtitle'), ), // Add more ListTiles as needed ], ), ), ); } }

2. Using Column Widget

If you want more control over the layout, you can use the Column widget to create a custom layout for your title and subtitle.

Example:

import 'package:flutter/material.dart'; void main() { runApp(MyApp()); } class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( home: Scaffold( appBar: AppBar(title: Text('Custom Subtitle Example')), body: Center( child: Column( mainAxisAlignment: MainAxisAlignment.center, children: <Widget>[ Text( 'Main Title', style: TextStyle(fontSize: 24, fontWeight: FontWeight.bold), ), SizedBox(height: 8), // Add spacing between title and subtitle Text( 'This is the subtitle', style: TextStyle(fontSize: 16, color: Colors.grey), ), ], ), ), ), ); } }

3. Using Card Widget

If you want to add a subtitle in a card format, you can use the Card widget along with Column to structure the title and subtitle.

Example:

import 'package:flutter/material.dart'; void main() { runApp(MyApp()); } class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( home: Scaffold( appBar: AppBar(title: Text('Card with Subtitle')), body: Center( child: Card( margin: EdgeInsets.all(16), child: Padding( padding: const EdgeInsets.all(16.0), child: Column( crossAxisAlignment: CrossAxisAlignment.start, children: <Widget>[ Text( 'Main Title', style: TextStyle(fontSize: 24, fontWeight: FontWeight.bold), ), SizedBox(height: 8), // Add spacing between title and subtitle Text( 'This is the subtitle', style: TextStyle(fontSize: 16, color: Colors.grey), ), ], ), ), ), ), ), ); } }

4. Using AppBar with bottom Property

If you need a subtitle in the AppBar, you can use the bottom property with a PreferredSize widget to include a subtitle.

Example:

import 'package:flutter/material.dart'; void main() { runApp(MyApp()); } class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( home: Scaffold( appBar: AppBar( title: Text('AppBar with Subtitle'), bottom: PreferredSize( preferredSize: Size.fromHeight(40.0), child: Column( crossAxisAlignment: CrossAxisAlignment.start, children: <Widget>[ Text( 'Main Title', style: TextStyle(fontSize: 20, fontWeight: FontWeight.bold), ), Text( 'This is the subtitle', style: TextStyle(fontSize: 14, color: Colors.white70), ), ], ), ), ), body: Center(child: Text('Body Content')), ), ); } }

Summary

  • ListTile: Easy way to add subtitle with built-in properties.
  • Column: Offers flexibility for custom layouts.
  • Card: For a card-like appearance with title and subtitle.
