I have a custom border to draw around a widget. I have attached an image
Can anyone have an idea how to do this in flutter without a custom painter?
Please notice it doesn't have a bottom border.
Container(
height: 100,
width: 200,
alignment: Alignment.center,
decoration: const BoxDecoration(
border: Border(
top: BorderSide(width: 5.0, color: Colors.black),
left: BorderSide(width: 5.0, color: Colors.black),
right: BorderSide(width: 5.0, color: Colors.black),
bottom: BorderSide(width: 0, color: Colors.white),
),
color: Colors.white,
),
child: const Text('OK', textAlign: TextAlign.center, style: TextStyle(color: Color(0xFF000000))),
)
Wrap the widget with Container
Container(
decoration: BoxDecoration(
border: Border.all(width: 5.0, color: Colors.black),
borderRadius: BorderRadius.circular(20.0) )// change value as per your needs
child: //your widget
)
Try below code hope its help to you.
If you want only Top corner are rounded :
Container(
width: double.infinity,
height: 100,
decoration: BoxDecoration(
borderRadius: const BorderRadius.only(
topLeft: Radius.circular(10),
topRight: Radius.circular(10),
),
border: Border.all(
width: 3,
color: Colors.black,
),
),
),
Result top rounded corner:
If you want all container rounded :
Container(
width: double.infinity,
height: 100,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(10),
border: Border.all(
width: 5,
color: Colors.black,
),
),
),
All rounded contaner result:
Please Refer Below code:
Padding(
padding: const EdgeInsets.all(15.0),
child: ClipRRect(
borderRadius:
BorderRadius.all(Radius.circular(7)),
child: Container(
height: 100,
width: double.infinity,
decoration: BoxDecoration(
border: Border(
left: BorderSide(
color: Colors.black,
width: 4.0,
),
top: BorderSide(
color: Colors.black,
width: 4.0,
),
right: BorderSide(
color: Colors.black,
width: 4.0,
),
),
),
child: Center(
child: Text('Custom Border'),
),
),
),
)
How can I add a rounded border for only 3 sides of the box? It's giving me errors if i add an "only" per sides if there is a border radius included.
this is my Code
Container(
padding: const EdgeInsets.all(10.0),
decoration: BoxDecoration(
border: Border.all(color:Colors.grey, width: 2.5),
borderRadius: BorderRadius.circular(13.0),
),
child: child,
)
I didn't quite get the screenshot but to have border for three sides, say for only left, right and bottom, use:
final borderSide = BorderSide(color: Colors.white, width: 2);
Container(
decoration: BoxDecoration(
border: Border(
left: borderSide,
right: borderSide,
bottom: borderSide,
),
),
child: child,
)
simply use .only in place of .circular
Container(
padding: const EdgeInsets.all(10.0),
decoration: BoxDecoration(
border: Border.all(color:Colors.grey, width: 2.5),
borderRadius: BorderRadius.only(topLeft: Radius.circular(13.0),topRight: Radius.circular(13.0)),
),
child: child,
)
Similarly you can add bottomLeft and bottomRight in .only
I want to make a button with two rounded borders inside each other.
It should look like this
But currently it looks like this
I tried to set a BoxDecoration to a Container and tried to expand the Container with Expanded or SizedBox.expand but it just doesn't stretch
return FittedBox(
child: RaisedButton(
padding: EdgeInsets.all(2),
onPressed: () {},
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(10),
side: BorderSide(color: Colors.red, width: 3)
),
child: Padding(
padding: EdgeInsets.all(3),
child: Expanded(
child: Container(
child: Text("Text"),
decoration: BoxDecoration(
border: Border.all(color: Colors.blue, width: 3),
borderRadius: BorderRadius.circular(10),
),
),
)
)
)
);
Is there a better way to do draw a border inside a button?
Use GestureDetector flutter to get the button work, and use
Container()
Center()
to achieve your aforementioned design. Also, read about BoxDecoration class. It will help you in great extent. Rest you will get to know from the below code itself.
Code
GestureDetector(
onTap: () => print('Hello'),
child: Container(
height: MediaQuery.of(context).size.height * 0.1,
width: MediaQuery.of(context).size.width * 0.2,
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.circular(12.0),
// play with width to get the width of the border
border: Border.all(color: Colors.red, width: 5.0),
// play with blurRadius, and offset for the shadow
boxShadow: [BoxShadow(color: Colors.grey, blurRadius: 9.0, offset: Offset(5.0, 5.0))]
),
child: Container(
// play with margin for inside border
margin: EdgeInsets.all(6.0),
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(12.0),
// play with width to get the width of the border
border: Border.all(color: Colors.blue, width: 5.0)
),
child: Center(
child: Text('Text', textAlign: TextAlign.center)
)
)
)
)
Result
Remove the FittedBox and wrap the inner Container with a SizedBox.expand:
RaisedButton(
padding: EdgeInsets.all(2),
onPressed: () {},
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(10),
side: BorderSide(color: Colors.red, width: 3)),
child: Padding(
padding: EdgeInsets.all(3),
child: SizedBox.expand(
child: Container(
child: Center(child: Text("Text")),
decoration: BoxDecoration(
border: Border.all(color: Colors.blue, width: 3),
borderRadius: BorderRadius.circular(10),
),
),
)))
Result:
Border radius not apply inside child Container.
Tried with SizedBox & Stack widget.
I need border view inside container.
Scaffold(
appBar: AppBar(
title: new Text("ListView"),
),
body: Center(
child: Padding(
padding: EdgeInsets.all(15.0),
child: Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(15.0),
border: Border.all(
color: Colors.green,
width: 2.0
)
),
child: Container(
color: Colors.red,
)
),
)
)
)
Try this,
Use ClipRRect and nest inside another Container and now you can add non-uniform borders
Container(
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.circular(10),
boxShadow: [BoxShadow(color: Colors.black12, blurRadius: 5)],
),
child: ClipRRect(
borderRadius: BorderRadius.circular(10),
child: Container(
padding: EdgeInsets.all(20),
decoration: BoxDecoration(
border: Border(
left: BorderSide(color: Colors.indigo, width: 5),
),
),
child: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Icon(Icons.home),
Text("Home"),
],
),
),
),
)
Other answers already state that you need to use ClipRRect to apply the border radius to the child widget of Container.
However, Container widget now has its clipBehaviour property to clip its child:
Container(
// Add the line below
clipBehavior: Clip.hardEdge,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(15.0),
border: Border.all(color: Colors.green, width: 2.0)),
child: Container(
color: Colors.red,
),
);
It's a good pratice to use this property rather than nest the widgets for a clean code.
decoration is painted behind the child. If you want the decoration to be applied in front of the container's child, use foregroundDecoration
Scaffold(
appBar: AppBar(
title: new Text("ListView"),
),
body: Center(
child: Padding(
padding: EdgeInsets.all(15.0),
child: Container(
foregroundDecoration: BoxDecoration(
borderRadius: BorderRadius.circular(15.0),
border: Border.all(
color: Colors.green,
width: 2.0
)
),
child: Container(
color: Colors.red,
)
),
)
)
)
above code paints border in front of the child container. Please note that, even with foregroundDecoration child container would still have sharp corners.
If you want the child container to have rounded corners, either you need apply borderRadius to the child container or use ClipRRect with same border radius as the parent container
Instead of
Container
widget use
ClipRRect
Before (not working):
Center(
child: Container(
decoration: BoxDecoration(
borderRadius: _getAllRoundedBorderRadius(),
),
child: Hero(
tag: "CossackHero",
child: TweenImage(
last: AssetImage("images/background/cossack_0.jpg"),
first: AssetImage("images/background/c_cossack_0.jpg"),
duration: 2,
height: height,
),
),
),
),
After:
Center(
child: ClipRRect(
borderRadius: getAllRoundedBorderRadius(),
child: Hero(
tag: "CossackHero",
child: TweenImage(
last: AssetImage("images/background/cossack_0.jpg"),
first: AssetImage("images/background/c_cossack_0.jpg"),
duration: 2,
height: height,
),
),
),
),
Screenshot:
With ClipRRect (Using 2 Container)
ClipRRect(
borderRadius: BorderRadius.circular(16),
child: Container(
width: 100,
height: 100,
color: Colors.black,
child: Container(
margin: EdgeInsets.all(8),
color: Colors.blue,
),
),
)
Without ClipRRect (Using 1 Container)
Container(
width: 100,
height: 100,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(16),
border: Border.all(
color: Colors.black,
width: 4,
),
color: Colors.blue,
),
)
Replace your code with this
Scaffold(
appBar: AppBar(
title: new Text("ListView"),
),
body: Center(
child: Padding(
padding: EdgeInsets.all(15.0),
child: Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(15.0),
border: Border.all(
color: Colors.green,
width: 2.0
)
),
child: Container(
decoration: new BoxDecoration(borderRadius:
BorderRadius.circular(15.0),
color: Colors.red,),
)
),
)
)
)
const innerRadius = 15.0;
const borderWidth = 2.0;
const borderColor = Colors.green;
const color = Colors.red;
const size = 100.0;
Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(innerRadius + borderWidth),
color: borderColor,
),
padding: EdgeInsets.all(borderWidth),
child: ClipRRect(
borderRadius: BorderRadius.circular(innerRadius),
child: Container(
color: color,
width: size,
height: size,
),
),
);
This is how it looks:
And how it works: https://codepen.io/mshibanami/pen/LYyQJXa
By the way, some answers suggest you using one Container that has decoration including border and color like this:
Container(
width: size,
height: size,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(innerRadius),
border: Border.all(
color: borderColor,
width: borderWidth,
),
color: color,
),
)
It's OK but not ideal because the inner color appears slightly outside the border. So when the border is close to the background color, it may stand out like this:
try
decoration: BoxDecoration(
gradient: new LinearGradient(
begin: Alignment.topCenter,
end: Alignment.bottomCenter,
stops: [0.02, 0.02],
colors: [Colors.red, Colors.white],
),
borderRadius: BorderRadius.all(Radius.circular(10)),
color: Colors.white,
boxShadow: [
BoxShadow(color: Colors.grey, blurRadius: 5.0),
],
),
you have to just add these line of code clipBehavior:Clip.hardEdge,
Scaffold(
appBar: AppBar(
title: new Text("ListView"),
),
body: Center(
child: Padding(
padding: EdgeInsets.all(15.0),
child: Container(
clipBehavior:Clip.hardEdge,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(15.0),
border: Border.all(
color: Colors.green,
width: 2.0
)
),
child: Container(
color: Colors.red,
)
),
)
)
)
I guess your container might just not be visible because it has no child/height/width.
Try adding some Text as a child or if you want it to expand, you can force with SizedBox.expand.
See this answer for example on borders.
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.
You can add the Text as a child to a Container that has a BoxDecoration with border property:
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'),
)
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.
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
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
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
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
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.
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"),
)
you can wrap that widget to DecoratedBox that provide decoration to that widget in that case
Widget textDecoration(String text){
return DecoratedBox(
decoration: BoxDecoration(
border: Border.all(
color: Colors.red,
width: 10,
),
),
child: Text(text)
);
}
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.
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:
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),
),
);
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,
)
Summary
I have tried to summarize all the important posibilities when using border in BoxDecoration.
Outcomes of the below explained borders:
Explaination
Basic
Container(
decoration: BoxDecoration(border: Border.all()),
child: const Text("Text"),
),
BorderColor, width and strokeAlign
Container(
decoration: BoxDecoration(
border: Border.all(
width: 4,
color: Colors.green,
strokeAlign: BorderSide.strokeAlignCenter)),
child: const Text("Text"),
),
Border only on specific side
Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
Container(
decoration: const BoxDecoration(
border: Border(top: BorderSide(width: 2))),
child: const Text("Text"),
),
Container(
decoration: const BoxDecoration(
border: Border(bottom: BorderSide(width: 2))),
child: const Text("Text"),
),
Container(
decoration: const BoxDecoration(
border: Border(
top: BorderSide(width: 2),
bottom: BorderSide(width: 4))),
child: const Text("Text"),
),
],
),
Different Shapes
Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
Container(
padding: const EdgeInsets.all(10),
decoration: BoxDecoration(
border: Border.all(),
shape: BoxShape.circle),
child: const Text("Text"),
),
Container(
padding: const EdgeInsets.all(10),
decoration: BoxDecoration(
border: Border.all(),
borderRadius: BorderRadius.circular(10),
),
child: const Text("Text"),
),
],
),
Curved Border Radius
Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
Container(
padding: const EdgeInsets.all(10),
decoration: BoxDecoration(
border: Border.all(),
borderRadius: const BorderRadius.horizontal(
left: Radius.circular(5), right: Radius.circular(20))
),
child: const Text("Text"),
),
Container(
padding: const EdgeInsets.all(10),
decoration: BoxDecoration(
border: Border.all(),
borderRadius: const BorderRadius.only(
topLeft: Radius.circular(10),
bottomRight: Radius.circular(20))),
child: const Text("Text"),
),
],
),
You can use Container to contain your widget:
Container(
decoration: BoxDecoration(
border: Border.all(
color: Color(0xff000000),
width: 1,
)),
child: Text()
),
Use a container with Boxdercoration.
BoxDecoration(
border: Border.all(
width: 3.0
),
borderRadius: BorderRadius.circular(10.0)
);
In case someone would like a outlined/bordered text or apply multiple borders.
You could try this:
https://pub.dev/packages/outlined_text
DEMO
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'),
);
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,
);
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),
),
),
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],
),
),
],
)
use the Text widget inside a container and use decoration to border the text
decoration: BoxDecoration(
border: Border.all(
color: Color(0xff000000),
width: 1,
)),
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),
),
)
