In this tutorial, we’ll learn how to properly use Flutter textfield outline border color by using a practical Flutter code example.
Introduction: Flutter Textfield Outline Border Color?
Flutter textfield outline border color is as the name suggests, it is the color of the Flutter textfield border, when we use outline border then it covers all the border sides of the textfield. Don’t worry, I will now implement it using proper example so you can have a better idea of what outline border is and how can we change Flutter textfield outline border color.
Default Outline Border Color
Let’s see the default Flutter textfield outline border color. For that we have to use the decoration constructor of the Flutter textfield, then pass it input decoration class and by using the enabled and focused border constructors, we can pass the outline input border class. See the below code:
TextField( decoration: InputDecoration( enabledBorder: OutlineInputBorder(), focusedBorder: OutlineInputBorder(), ), )
Change Flutter Textfield Outline Border Color
Now let’s implement the customization of outline border color of Flutter textfield. For that we have to use the same process mentioned above and after that we have to use the border side constructor of the outline input border class and pass it the border side class. Using the color constructor of the border side class, we can change the color of the outline border of Flutter textfield. See the below code:
OutlineInputBorder( borderSide: BorderSide(color: Colors.green))
Custom Flutter Textfield Design 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(
style: TextStyle(color: Colors.purple),
decoration: InputDecoration(
enabledBorder: OutlineInputBorder(
borderRadius: BorderRadius.circular(50)
.copyWith(bottomRight: Radius.circular(0)),
borderSide: BorderSide(color: Colors.purple)),
focusedBorder: OutlineInputBorder(
borderRadius: BorderRadius.circular(50)
.copyWith(bottomRight: Radius.circular(0)),
borderSide: BorderSide(color: Colors.purple)),
),
))),
));
}
}Conclusion
To conclude this tutorial, now you’ve a detailed and in-depth practical knowledge of how to implement Flutter textfield outline border color. I’d love to have your feedback on this post.
I’d also love to see you visit my other tutorials on Flutter app development and Python programming as well. Thank you for reading this post.
