In this tutorial, we’ll learn how to properly use and customize Flutter textfield autoFocus by using a practical Flutter code example.
Introduction: Flutter Textfield AutoFocus
As the name suggests, it automatically drives the focus on a specific Flutter textfield.
For instance, a user navigates from a splash screen to login screen and you want the app to automatically drive the focus on email field. This is where Flutter textfield autoFocus comes into play.
Let’s now understand and implement it using a proper Flutter code example.
Customizing Flutter Textfield AutoFocus
For that, we’ve to use the autofocus constructor of Flutter textfield widget. This constructor takes a Boolean(true/false) value.
By default, the value is false. Let’s change it to true and see the results. See below code:
TextField( autofocus: true )
So this is how you can customize Flutter textfield autofocus in your own Flutter apps as well.
The complete source code of customized Flutter textfield autofocus is given in the below section.
Custom Flutter Textfield Autofocus Complete 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: TextField(
autofocus: true,
))),
));
}
}Conclusion
