Hi Guys welcome to Proto Coders Point, In the Tutorial, we will learn about the Flutter widget class i.e Rich Text.

Introduction to Flutter RichText widget

In Flutter, RichText is used to display multiply text styles.

Here, the text to be displayed is done using TextSpan objects.

The text which is displayed in the rich text widget should be styled explicitly. you can set a DefaultTextStyle using the current BuildContext to provide defaults. To learn more on how to style text in RichText Widget. see the documentation for TextStyle.

Implementation of Flutter Rich Text Example

ok, So we now know the basic of the above Flutter Text Widget. It’s time to implement the widget in our project. For that, we need to first create a new Flutter Project or you can continue with your existing one.

File > New > New Flutter Project

If you can’t find any option to create a flutter project that might be because you have not installed the flutter plugin into your android studio.

Example of Flutter RichText with Code.

Code

import 'package:flutter/material.dart';

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

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

class HomePage extends StatefulWidget {
  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("Rich Text Demo"),
      ),
      body: Padding(
        padding: const EdgeInsets.all(8.0),
        child: RichText(
          text: TextSpan(
            text: 'The harder you work for something,',
            style: TextStyle(fontSize: 15.0, color: Colors.lightBlue),
            children: <TextSpan>[
              TextSpan(
                text: ' The greater you\'ll feel when you achieve it',
                style: TextStyle(
                    fontWeight: FontWeight.w600,
                    fontSize: 20,
                    color: Colors.red),
              ),
            ],
          ),
        ),
      ),
    );

class HomePage extends StatefulWidget {
  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
