Flutter Basic Material Widgets


The Text widget displays a string of text with single style. Multiple line texts are allowed.
To style the entire text in one way, specify a ‘style’ property in the constructor of the Text Widget.
To style sections of the text, use child TextSpans (see example below).

Example – ‘text’

Every time you hit the ‘+’ a new word comes out in a different color.

Source Code

import 'package:flutter/material.dart';
void main() => runApp(new MyApp());
class MyApp extends StatelessWidget {
// This widget is the root of your application.
Widget build(BuildContext context) {
return new MaterialApp(
title: 'Flutter Styled Text Demo',
theme: new ThemeData(
home: new MyHomePage(),
class TextBlock {
final Color _color;
final String _text;
TextBlock(this._color, this._text);
String get text => _text;
Color get color => _color;
class MyHomePage extends StatefulWidget {
MyHomePage({Key key}) : super(key: key);
_MyHomePageState createState() => new _MyHomePageState();
class _MyHomePageState extends State<MyHomePage> {
int _index = 0;
final List<TextBlock> textBlocks = [
TextBlock(, 'every'),
TextBlock(Colors.redAccent, ' schoolboy'),
TextBlock(, '\nknows'),
TextBlock(Colors.greenAccent, ' who'),
TextBlock(, '\nimprisoned'),
TextBlock(Colors.blueAccent, '\nMontezuma')
void _incrementCounter() {
setState(() {
if (_index < textBlocks.length) {
Widget build(BuildContext context) {
final List<TextSpan> textSpans = List<TextSpan>();
for (var i = 0; i < _index; i++) {
TextBlock textBlock = textBlocks[i];
text: textBlock.text,
style: TextStyle(color: textBlock.color, fontSize: 32.0)));
return new Scaffold(
body: new Center(
child: new Column(
children: <Widget>[ textSpans))],
floatingActionButton: new FloatingActionButton(
onPressed: _incrementCounter,
tooltip: 'Increment',
child: new Icon(Icons.note_add),
), // This trailing comma makes auto-formatting nicer for build methods.
