How can I add a border to a widget in Flutter?

Question

I'm using Flutter and I'd like to add a border to a widget (in this case, a Text widget).

I tried TextStyle and Text, but I didn't see how to add a border.

Answer 1

You can add the Text as a child to a Container that has a BoxDecoration with border property:

enter image description here

Container(
 margin: const EdgeInsets.all(15.0),
 padding: const EdgeInsets.all(3.0),
 decoration: BoxDecoration(
 border: Border.all(color: Colors.blueAccent)
 ),
 child: Text('My Awesome Border'),
)

Answer 2

Here is an expanded answer. A DecoratedBox is what you need to add a border, but I am using a Container for the convenience of adding margin and padding.

Here is the general setup.

enter image description here

Widget myWidget() {
 return Container(
 margin: const EdgeInsets.all(30.0),
 padding: const EdgeInsets.all(10.0),
 decoration: myBoxDecoration(), // <--- BoxDecoration here
 child: Text(
 "text",
 style: TextStyle(fontSize: 30.0),
 ),
 );
}

where the BoxDecoration is

BoxDecoration myBoxDecoration() {
 return BoxDecoration(
 border: Border.all(),
 );
}

Border width

enter image description here

These have a border width of 1, 3, and 10 respectively.

BoxDecoration myBoxDecoration() {
 return BoxDecoration(
 border: Border.all(
 width: 1, // <--- border width here
 ),
 );
}

Border color

enter image description here

These have a border color of

• Colors.red
• Colors.blue
• Colors.green

Code

BoxDecoration myBoxDecoration() {
 return BoxDecoration(
 border: Border.all(
 color: Colors.red, // <--- border color
 width: 5.0,
 ),
 );
}

Border side

enter image description here

These have a border side of

• left (3.0), top (3.0)
• bottom (13.0)
• left (blue[100], 15.0), top (blue[300], 10.0), right (blue[500], 5.0), bottom (blue[800], 3.0)

Code

BoxDecoration myBoxDecoration() {
 return BoxDecoration(
 border: Border(
 left: BorderSide( // <--- left side
 color: Colors.black,
 width: 3.0,
 ),
 top: BorderSide( // <--- top side
 color: Colors.black,
 width: 3.0,
 ),
 ),
 );
}

Border radius

enter image description here

These have border radii of 5, 10, and 30 respectively.

BoxDecoration myBoxDecoration() {
 return BoxDecoration(
 border: Border.all(
 width: 3.0
 ),
 borderRadius: BorderRadius.all(
 Radius.circular(5.0) // <--- border radius here
 ),
 );
}

Going on

DecoratedBox/BoxDecoration are very flexible. Read Flutter — BoxDecoration Cheat Sheet for many more ideas.

• Robert Williams: @HaSnenTai Did you find any solution? In my design i need to give border bottom with pill like shape. How can i achieve this?
• Suragch: @RobertWilliams, I would use a custom drawing widget.
• Robert Williams: @Suragch The widget is Text which needs a strong (pill shaped) border. The text widget width is not fixed. For using custom drawing widget won't I need to provide fix properties?
• Son Nguyen: U can also use the short-hand BorderRadius.circular(8) instead of BorderRadius.all(Radius.circular(5.0)).

Answer 3

The best way is using BoxDecoration()

Advantage

• You can set the border of a widget
• You can set the border Color or Width
• You can set a Rounded corner of a border
• You can add a Shadow of a widget

Disadvantage

• BoxDecoration only use with Container widget, so you want to wrap your widget in Container()

Example

 Container(
 margin: EdgeInsets.all(10),
 padding: EdgeInsets.all(10),
 alignment: Alignment.center,
 decoration: BoxDecoration(
 color: Colors.orange,
 border: Border.all(
 color: Colors.pink[800], // Set border color
 width: 3.0), // Set border width
 borderRadius: BorderRadius.all(
 Radius.circular(10.0)), // Set rounded corner radius
 boxShadow: [BoxShadow(blurRadius: 10,color: Colors.black,offset: Offset(1,3))] // Make rounded corner of border
 ),
 child: Text("My demo styling"),
 )

Enter image description here

Answer 4

You can wrap the widget with DecoratedBox which provides decoration :

Widget textDecoration(String text){
 return DecoratedBox(
 decoration: BoxDecoration(
 border: Border.all(
 color: Colors.red,
 width: 10,
 ),
 ),
 child: Text(text)
 );
}

Answer 6

As stated in the documentation, Flutter prefers composition over parameters.

Most of the time you're not looking for a property, but instead a wrapper (and sometimes a few helpers/"builder").

For borders, you want DecoratedBox, which has a decoration property that defines borders; but also background images or shadows.

Alternatively, like Aziza said, you can use Container. Which is the combination of DecoratedBox, SizedBox and a few other useful widgets.

Answer 7

Here, as the Text widget does not have a property that allows us to define a border, we should wrap it with a widget that allows us to define a border. There are several solutions. But the best solution is the use of BoxDecoration in the Container widget.

Why choose to use BoxDecoration?

Because BoxDecoration offers more customization like the possibility to define:

First, the border and also define:

• border Color
• border width
• border radius
• shape
• and more ...

An example:

 Container(
 child:Text(' Hello Word '),
 decoration: BoxDecoration(
 color: Colors.yellow,
 border: Border.all(
 color: Colors.red ,
 width: 2.0 ,
 ),
 borderRadius: BorderRadius.circular(15),
 ),
 ),

Output:

Enter image description here

Answer 8

Wrap that widget with the container

Container(
 margin: const EdgeInsets.all(30.0),
 padding: const EdgeInsets.all(10.0),
 decoration: BoxDecoration(border: Border.all(
 color: Colors.black,
 width: 1,
 ),
 ), 
 child: Text(
 "text",
 style: TextStyle(fontSize: 30.0),
 ),
 );

Answer 9

The above answers are also correct, but in case you want to add multiple borders at the same widget, then you can set this

Container(
 child: const Center(
 child: Text(
 'This is your Container',
 ),
 ),
 decoration: BoxDecoration(
 borderRadius: BorderRadius.circular(10),
 color: Colors.white,
 boxShadow: const [
 BoxShadow(color: Colors.green, spreadRadius: 8),
 BoxShadow(color: Colors.yellow, spreadRadius: 5),
 ],
 ),
 height: 50,
 )

enter image description here

Answer 10

You can use Container to contain your widget:

Container(
 decoration: BoxDecoration(
 border: Border.all(
 color: Color(0xff000000),
 width: 1,
 )),
 child: Text()
),

Answer 11

Use a container with Boxdercoration.

 BoxDecoration(
 border: Border.all(
 width: 3.0
 ),
 borderRadius: BorderRadius.circular(10.0)
 );

Answer 13

You can use this method for adding border colour for a container.

Container(
 height: height * 0.06,
 width: width,
 alignment: Alignment.center,
 decoration: BoxDecoration(
 border: Border.all(
 color: primaryColor,
 ),
 borderRadius: BorderRadius.circular(10),
 ),
 child: Text(
 "data",
 style: const TextStyle(
 fontWeight: FontWeight.bold
 ),
 ),
 );

Answer 14

You can achieve bottom rounded corner with three side borders.

Stack(
children: [
 Container(
 decoration: BoxDecoration(
 border: Border.all(color: Colors.red, width: 2),
 borderRadius: const BorderRadius.only(
 topLeft: Radius.zero,
 topRight: Radius.zero,
 bottomLeft: Radius.circular(20),
 bottomRight: Radius.circular(20),
 ),
 ),
 child: Padding(
 padding: const EdgeInsets.all(20.0),
 child: Column(
 crossAxisAlignment: CrossAxisAlignment.start,
 children: [
 const SizedBox(
 height: 1,
 ),
 Text("Dummy text"),
 const SizedBox(
 height: 10,
 ),
 ],
 ),
 ),
 ),
 Padding(
 padding: const EdgeInsets.only(left: 2, right: 2),
 child: Container(
 color: AppColors.highLighterBg,
 width: size.width,
 height: 10,
 ),
 )
],

);

Answer 15

 In Flutter, you can add a border to a widget using the Container widget and its decoration property. The BoxDecoration class allows you to define various visual elements, including borders.
 import 'package:flutter/material.dart';
void main() {
 runApp(MyApp());
}
class MyApp extends StatelessWidget {
 @override
 Widget build(BuildContext context) {
 return MaterialApp(
 home: Scaffold(
 appBar: AppBar(
 title: Text('Border Example'),
 ),
 body: Center(
 child: Container(
 width: 200,
 height: 100,
 decoration: BoxDecoration(
 border: Border.all(
 color: Colors.blue, // Set border color
 width: 2.0, // Set border width
 ),
 borderRadius: BorderRadius.circular(8.0), // Set border radius
 ),
 child: Center(
 child: Text(
 'Hello, Border!',
 style: TextStyle(fontSize: 16),
 ),
 ),
 ),
 ),
 ),
 );
 }
}

Answer 16

In Flutter, the Text widget itself does not have a direct property for adding a border. However, you can achieve this effect in multiple ways, and this an a way:

Using Container with BoxDecoration

Container(
 decoration: BoxDecoration(
 border: Border.all(color: Colors.blue, width: 2), 
 ),
 padding: EdgeInsets.all(8), // Optional padding
 child: Text(
 'Hello, Flutter!',
 style: TextStyle(fontSize: 20),
 ),
)

Answer 17

If you want to add border to some text of container then you can easily to do it by applying BoxDecoration to Container.

code :

Container(
 decoration: BoxDecoration(
 border: Border.all(
 color: Colors.redAccent,
 width: 1,
 ),
 ),
 child: Text('Some Text'),
);

Answer 18

Rounded corner/border with bottom shadow

Container(
 // child it's depend on your requirement
 child: const Center(
 child: Text(
 'This is your Container',
 ),
 ),
 decoration: BoxDecoration(
 borderRadius: BorderRadius.circular(10),
 color: Colors.white,
 boxShadow: <BoxShadow>[
 // shadow color and radius
 BoxShadow(
 color: Colors.black54,
 blurRadius: 15.0,
 offset: Offset(0.0, 0.75)
 )
 ],
 ),
 // according your height ex. 50
 height: 50,
);

Answer 19

Try the following code:

Container(
 margin: margin,
 padding: padding,
 decoration: BoxDecoration(
 border: Border.all(
 color: color,
 width: width,
 ),
 ),
 child: Text(
 data,
 style: TextStyle(fontSize: 30.0),
 ),
),

Answer 20

Text border style:

Stack(
 children: <Widget>[
 // Stroked text as border.
 Text(
 'Greetings, planet!',
 style: TextStyle(
 fontSize: 40,
 foreground: Paint()
 ..style = PaintingStyle.stroke
 ..strokeWidth = 6
 ..color = Colors.blue[700]!,
 ),
 ),
 // Solid text as fill.
 Text(
 'Greetings, planet!',
 style: TextStyle(
 fontSize: 40,
 color: Colors.grey[300],
 ),
 ),
 ],
)

Answer 21

Yes, there's different approaches for that. One of them is: Wrap it in a container. And use box decoration like this.

Container(
 padding: const EdgeInsets.all(16.0),
 decoration: BoxDecoration(
 border: Border.all(width: 5, color: Colors.red),
 borderRadius: BorderRadius.all(Radius.circular(50)),
 ), 
 child: const Text(
 "Box decoration",
 style: TextStyle(fontSize: 34.0),
 ),
)

Answer 22

Container is expensive, if you only want to add a border to a widget use DecoratedBox instead:

DecoratedBox(
 decoration: BoxDecoration(
 border: Border.all(color: appColorScheme(context).secondary),
 borderRadius: BorderRadius.circular(CupertinoContextMenu.kOpenBorderRadius),
 ),
 child: //Your Widget,
)

Answer 23

use the Text widget inside a container and use decoration to border the text:

decoration: BoxDecoration(
 border: Border.all(
 color: Color(0xff000000),
 width: 1,
)),

Answer 24

Just wrap the widget with container and decorate the container as you want.

Answer 25

To add a border to your Text widget in Flutter, wrap it with a Container and use BoxDecoration for decoration:

Container(
 decoration: BoxDecoration(
 border: Border.all(
 color: Colors.black, // Adjust color as needed
 width: 2.0, // Adjust width as needed
 ),
 ),
 child: Text(
 'Your Text Here',
 ),
)

This creates a black border around your text. Adjust color and width as needed.
