Flutter BorderRadius of Card doesn't apply for child: Container? - flutter

I have the follwing code and I wonder how to make Container take the Cards BorderRadius? The only way I know is to add BorderRadius to BoxDecoration of Container, but is this the right way? How could I do better?
Align(
child: Card(
elevation: 10,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(20),
),
child: Container(
width: 200,
height: 200,
decoration: BoxDecoration(
gradient: LinearGradient(
colors: [Color(0xff232526),Color(0xff414345) ],
begin: Alignment.bottomCenter,
// stops: [0.1,1],
end: Alignment.topCenter,
),
),
child: RadialGauge(
counter: snapshot.data['Strom'].toDouble(),
).buildGauge(),
),
),
),

you can use Clip.hardEdge, will cut out the excess
Card(
clipBehavior: Clip.hardEdge,
elevation: 10,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(20),
),
child:...

in your boxDeocration of the containner add this
borderRadius: BorderRadius.circular(radius),

How do you give a CircleAvatar multiple border colors in Flutter?

I'm wondering if there is a simple way to give a circle avatar multiple border colors in Flutter.
Bonus if you could set the % you want each color to fill.
Here is an image of what I mean, but note it wasn't that easy to do in Figma, hence the blurring of the colors. Color blending actually would not be the preferred behavior.
This is what came to my mind. You can change the color list to match the Figma gradient.
Container(
height: 80,
width: 80,
decoration: const BoxDecoration(
gradient: LinearGradient(colors: [
Colors.green,
Colors.yellow,
Colors.red,
Colors.purple
]),
shape: BoxShape.circle),
child: Padding(
//this padding will be you border size
padding: const EdgeInsets.all(3.0),
child: Container(
decoration: const BoxDecoration(
color: Colors.white, shape: BoxShape.circle),
child: const CircleAvatar(
backgroundColor: Colors.white,
foregroundImage: NetworkImage("https://i.ibb.co/rkG8cCs/112921315-gettyimages-876284806.jpg"),
),
),
),
),
Here is your solution,
Container(
decoration: BoxDecoration(
gradient: LinearGradient(
begin: Alignment.topRight,
end: Alignment.bottomLeft,
colors: [
Color(0XFF8134AF),
Color(0XFFDD2A7B),
Color(0XFFFEDA77),
Color(0XFFF58529),
],
),
shape: BoxShape.circle
),
child: Container(
decoration: BoxDecoration(
color: Colors.white,
shape: BoxShape.circle
),
margin: EdgeInsets.all(2),
child: Padding(
padding: const EdgeInsets.all(3.0),
child: CircleAvatar(
radius: 25,
backgroundColor: Colors.grey,
backgroundImage: NetworkImage(reels[i].image)
),
),
),
),

How to add gradient color in card?

How to add gradient color in the background of a card ? Should I reproduce this card with a container and a box decoration or is there another simple way ?
Try below code hope it help to you in below answer change Color your need.

height: 50,
width: 150,
decoration: BoxDecoration(
gradient: LinearGradient(
colors: [
Colors.yellow,
Colors.orangeAccent,
Colors.yellow.shade300,

I know it's a bit late, but you can try this to achieve a card gradient with border radius
return Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(12),
boxShadow: [
BoxShadow(
color: Colors.black38,
blurRadius: 3.0,
spreadRadius: 0.0,
offset: Offset(1.0, 1.0),
)
],
gradient: LinearGradient(
colors: [startColor, endColor],
begin: Alignment.bottomLeft,
end: Alignment.topRight,
),
),
child: Padding(
padding: const EdgeInsets.all(12),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
const SizedBox(height: 6),
TextWidget(
title,
typographyToken: TypographyToken.text14SemiBold,
color: Colors.white,

const SizedBox(height: 8),
TextWidget(
"$pendingCount Pending Request",
typographyToken: TypographyToken.text10,
color: Colors.white,
),
const SizedBox(height: 6),
],
),
),
);

This is a sample that I tried just now. Works fine for me.
Container(
decoration: BoxDecoration(
gradient: LinearGradient(
colors: [Colors.black, Colors.white],
begin: Alignment.topLeft,
end: Alignment.bottomRight)),
)
Another way and probably the best in my opinion:
Container(
decoration: BoxDecoration(
gradient: LinearGradient(
begin: Alignment.centerRight,
end: Alignment.center,
colors: [Colors.deepOrangeAccent, Colors.orange],
),
),
width: 300,
height: 300,
child: Card(
color: Colors.transparent,
),
),
Output:

Card(
shadowColor: tabColorAmber,

Is there a way to put a gradient colored border around a container?

What I have:
Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(35),
border: Border.all(
color: const Color(0xFFE800E8),//<---- Insert Gradient Here
width: 1.5,
)
),
),
This a visual representation of the border, which is currently pink, this is what I want to make gradient:
I'm not sure if there is a simpler way. But you could construct it using a couple of containers like this:
Container(
decoration: BoxDecoration(
gradient: LinearGradient(
colors: [
Colors.black,
Colors.pinkAccent,
],
),
borderRadius: BorderRadius.circular(35),
),
height: 100,
child: Padding(
padding: const EdgeInsets.all(1.5),
child: Container(
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.circular(35),
),
child: Center(
child: Text('Enter further widgets here'),
),
),
),
),

border radius not apply inside container widget

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.
