In this tutorial, we’ll learn how to easily implement Flutter textformfield hint text by using a proper practical Flutter example code.
Introduction: Flutter Textformfield Hint Text
Flutter textformfield hint text is as the name suggests, it shows a hint to the user about the input that the user should input in that Flutter textfield. It is really a good practice to use Flutter textformfield hint text in a Flutter textformfield because the user can have a better idea of what he/she should input in that particular Flutter textfield.
Flutter textformfield hint text is visible when the Flutter textfield is empty and disappears when the user starts inputting and reappears when the Flutter textformfield is empty again. It is shown in the same place where the inputted text is shown in the Flutter textformfield. Let’s now understand it using a proper and easy Flutter example code.
Customize Flutter Textformfield Hint Text
By default, our Flutter textfield won’t show any hint text. So in order to customize and show hint text in Flutter textformfield, we have to use the decoration constructor of the Flutter textformfield. Passing the input decoration class and using the hint text constructor of the input decoration class. Using this hint text constructor, we can now specify our own hint text.
This hint text constructor only takes a string, means only a text can be inputted in it. Let’s now implement it using Flutter code. See the below code for this:
TextFormField( decoration: InputDecoration( hintText: 'This is hint text', ), )
Custom Flutter Textformfield 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 StatefulWidget {
@override
State<Homepage> createState() => _HomepageState();
}
class _HomepageState extends State<Homepage> {
@override
Widget build(BuildContext context) {
return SafeArea(
child: Scaffold(
body: Center(
child: Padding(
padding: EdgeInsets.symmetric(horizontal: 40),
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
TextFormField(
style: TextStyle(color: Colors.white),
cursorColor: Colors.green,
decoration: InputDecoration(
hintText: 'This is hint text',
hintStyle: TextStyle(color: Colors.white70),
prefixIcon: Icon(
Icons.person,
color: Colors.white70,
),
border: InputBorder.none,
filled: true,
fillColor: Colors.green.withOpacity(.6),
contentPadding: EdgeInsets.all(26),
enabledBorder: OutlineInputBorder(
borderSide: BorderSide(color: Colors.transparent),
borderRadius: BorderRadius.circular(30).copyWith(
topRight: Radius.circular(0),
bottomLeft: Radius.circular(0))),
focusedBorder: OutlineInputBorder(
borderSide: BorderSide(color: Colors.transparent),
borderRadius: BorderRadius.circular(30).copyWith(
topRight: Radius.circular(0),
bottomLeft: Radius.circular(0)))),
)
],
))),
));
}
}Conclusion
