Flutter textformfield default value. In this article, I will be discussing and implementing Flutter textformfield default value. I will be discussing the role, usage and importance of Flutter textformfield default value and how can you set a custom value according to your Flutter app requirements. So let’s not waste anymore of your precious time and start implementing custom Flutter textformfield default value.
Why is Flutter Textformfield Default Value Used?
Flutter textformfield default value is used when you want to automatically show a value in the Flutter textformfield, let’s say we have a description and we want to edit this description using the Flutter textformfield, so for that we have to use the Flutter textformfield default value to store the already present text of the description and show it in the Flutter textformfield so user don’t have to write the already present description again, in this way, the user can add to this description or delete it and create a new description.
So this is how Flutter textformfield default value works. Don’t worry I will explain Flutter textformfield default value using a proper example for you to better understand the importance of it.
Custom Flutter Textformfield Default Value
Let’s now give our Flutter textformfield default value default value a custom value to test how it works. For that, you have to use the initial value constructor of the Flutter textformfield. This initial value constructor takes a string only. Let’s implement it using code:
TextFormField( initialValue: 'This is the initial/default value', )
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(
initialValue: 'This is the initial value',
style: TextStyle(color: Colors.green),
cursorColor: Colors.green,
decoration: InputDecoration(
border: InputBorder.none,
filled: true,
fillColor: Colors.green.withOpacity(.08),
prefixIcon: Icon(
Icons.person,
color: Colors.green,
),
suffixIcon: Icon(
Icons.visibility,
color: Colors.green,
),
enabledBorder: OutlineInputBorder(
borderSide: BorderSide(
color: Colors.green.withOpacity(.05)),
borderRadius: BorderRadius.circular(30).copyWith(
bottomRight: Radius.circular(0),
bottomLeft: Radius.circular(0))),
focusedBorder: OutlineInputBorder(
borderSide: BorderSide(
color: Colors.green.withOpacity(.05)),
borderRadius: BorderRadius.circular(30).copyWith(
bottomRight: Radius.circular(0),
bottomLeft: Radius.circular(0)))),
)
],
))),
));
}
}Conclusion
