Flutter textfield hint text customization. In this article, I will be implementing Flutter textfield hint text in Flutter app and also discuss it’s usage and role in Flutter textfield. I will be using a proper easy Flutter example code so you can have a better understanding of how to use and customize Flutter textfield hint text in Flutter textfield.
What is Flutter Textfield Hint Text?
Flutter textfield 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 textfield hint text in a Flutter textfield because the user can have a better idea of what he/she should input in that particular Flutter textfield.
Flutter textfield hint text is visible when the Flutter textfield is empty and disappears when the user starts inputting and reappears when the Flutter textfield is empty again. It is shown in the same place where the inputted text is shown in the Flutter textfield. Let’s now understand it using a proper and easy Flutter example code.
Custom Flutter Textfield Hint Text
By default, our Flutter textfield won’t show any hint text. So in order to customize and show hint text in Flutter textfield, we have to use the decoration constructor of the Flutter textfield. 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:
TextField( decoration: InputDecoration( hintText: 'This is hint text', ), )
Custom Flutter Textfield 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: [
TextField(
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
In conclusion, now you have a detailed understanding of what Flutter textfield hint text is and how to customize it in your Flutter textfield. I would love to have your feedback on this post and also I would encourage you to visit my other articles on Flutter app development, Flutter widgets, Flutter animations, Flutter templates and many more.
