In this Flutter post, we are implementing a Flutter text underline and explaining it using a step-by-step approach so we can properly understand how to use it. We will describe the underline in Flutter text in detail so you don’t face any issues related to its customization. So what are we waiting for, let’s just get right into its implementation.
What is Flutter Text Underline?
Flutter text underline as the names already described, it is the underline of the text in Flutter text widget. By default, no underline is given to the Flutter text. We will see how to implement underline in Flutter text using a simple and easy Flutter example.
Implementing Flutter Text Underline
In order to implement the Flutter text underline, we first have to implement a Flutter text widget with some text so we can give underline to that text and then we have to use the style constructor of the Flutter text widget class. We can use the decoration constructor of the text style class and pass it TextDecoration.underline to give our Flutter text an underline. We also have used the font size to make the text look a bit bigger and also we have colored our Flutter text widget. See the below code:
Text( 'Flutter text underline is implemented', style: TextStyle( decoration: TextDecoration.underline, fontSize: 17, color: Colors.green), )

Flutter Text Underline Implementation Source Code
import 'package:flutter/material.dart'; void main() { runApp(const MyApp()); } class MyApp extends StatelessWidget { const MyApp({Key? key}) : super(key: key); @override Widget build(BuildContext context) { return MaterialApp( debugShowCheckedModeBanner: false, home: Homepage(), ); } } class Homepage extends StatelessWidget { @override Widget build(BuildContext context) { return SafeArea( child: Scaffold( body: Center( child: Padding( padding: const EdgeInsets.all(15), child: Text( 'Flutter text underline is implemented', style: TextStyle( decoration: TextDecoration.underline, fontSize: 17, color: Colors.green), )), ))); } }
