By default, the TextField widget of Flutter has an underline. Sometimes, you may want to get rid of this line. In this Flutter tutorial, let’s check how to remove underlining in TextField.
You can remove the underline by using InputBorder class as given below.
TextField(
controller: _controller,
decoration: const InputDecoration(
border: InputBorder.none, hintText: "TextInput without Underline"),
onSubmitted: (String value) {
debugPrint(value);
},
),Following is the complete code for reference.
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(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: const MyHomePage(),
);
}
}
class MyHomePage extends StatelessWidget {
const MyHomePage({super.key});
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('Flutter TextField Multiple Lines'),
),
body: const MyStatefulWidget());
}
}
class MyStatefulWidget extends StatefulWidget {
const MyStatefulWidget({super.key});
@override
State<MyStatefulWidget> createState() => _MyStatefulWidgetState();
}
class _MyStatefulWidgetState extends State<MyStatefulWidget> {
late TextEditingController _controller;
@override
void initState() {
super.initState();
_controller = TextEditingController();
}
@override
void dispose() {
_controller.dispose();
super.dispose();
}
@override
Widget build(BuildContext context) {
return Center(
child: Padding(
padding: const EdgeInsets.all(16.0),
child: TextField(
controller: _controller,
decoration: const InputDecoration(
border: InputBorder.none, hintText: "TextInput without Underline"),
onSubmitted: (String value) {
debugPrint(value);
},
),
));
}
}
