I am trying to use the below code to create a circular border around an image and align an icon on top of the circular border. What I am looking at is as the image below:
And my code is as below but it didn't work out perfectly:
Stack(
children: [
CircleAvatar(
radius: 60,
backgroundColor: Colors.white,
child: Container(
padding: EdgeInsets.all(2),
child: CircleAvatar(
radius: 70,
backgroundImage: AssetImage('assets/person_icon.png'),
backgroundColor: Colors.white,
//
)),
),
Positioned(
bottom: 100,
right: 50,
child: InkWell(
onTap: () {},
child: Container(
child: Padding(
padding: const EdgeInsets.all(2.0),
child: Icon(Icons.add_a_photo, color: colorBlue),
),
decoration: BoxDecoration(
border: Border.all(
width: 3,
color: Colors.white,
),
borderRadius: BorderRadius.all(
Radius.circular(
50,
),
),
color: Colors.white,
boxShadow: [
BoxShadow(
offset: Offset(2, 4),
color: Colors.black.withOpacity(
0.3,
),
blurRadius: 3,
),
]),
),
)),
],
),
As you can above I am trying to use stack to lay each widget on top of each other but couldn't achieve that. I don't if anyone can help out where I missed it or give me a good idea of how to come about this.
Thanks in advance.
CodePudding user response：
Just add to the Stack Widget the Property clipBehavior: Clip.none,.
The clipBehavior will befine how to handle the Clip of the Stack Widget. Standard is hardEdge and cuts your icon off.
So your finished working Code is import 'package:flutter/material.dart';
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: Stack(
clipBehavior: Clip.none,
children: [
CircleAvatar(
radius: 60,
backgroundColor: Colors.white,
child: Container(
padding: EdgeInsets.all(2),
child: CircleAvatar(
radius: 70,
backgroundImage: AssetImage('assets/person_icon.png'),
backgroundColor: Colors.white,
//
),
),
),
Positioned(
bottom: 100,
right: 50,
child: InkWell(
onTap: () {},
child: Container(
child: Padding(
padding: const EdgeInsets.all(2.0),
child: Icon(Icons.add_a_photo, color: Colors.blue),
),
decoration: BoxDecoration(
border: Border.all(
width: 3,
color: Colors.white,
),
borderRadius: BorderRadius.all(
Radius.circular(
50,
),
),
color: Colors.white,
boxShadow: [
BoxShadow(
offset: Offset(2, 4),
color: Colors.black.withOpacity(
0.3,
),
blurRadius: 3,
),
],
),
),
),
),
],
),
),
);
}
}
void main() {
runApp(
const MaterialApp(
home: MyApp(),
),
);
}

Try below code
Stack(
children: <Widget>[
Padding(
padding: EdgeInsets.only(top: 25),
child: Container(
padding: EdgeInsets.all(8),
height: 270,
width: 270,
decoration: BoxDecoration(
color: Colors.green,
shape: BoxShape.circle,
),
child: Container(
padding: EdgeInsets.all(8),
decoration: BoxDecoration(
color: Colors.white,
shape: BoxShape.circle,
),
child: ClipOval(
child: Container(
height: 250,
width: 250,
child: Image.network(
'https://miro.medium.com/max/1400/1*-6WdIcd88w3pfphHOYln3Q.png',
fit: BoxFit.cover,
),
),
),

Positioned(
top: 0,
left: .0,
right: .0,
child: Center(
child: CircleAvatar(
backgroundColor: Colors.green,

Default clipBehavior on Stack is hardEdge.
- Use
clipBehavior: Clip.noneon Stack.
And to have circle shape
use
customBorder: CircleBorder(),onInkWell.use
shape: BoxShape.circleinstead of circular radius on container.
For better alignment use
Positioned(
top: -12,//half of icon size
left: 0,
right: 0,
Also better providing size on Stack like here.
/// fixing top widget size
SizedBox.square(
dimension: squareSize,
child: Stack(
clipBehavior: Clip.none,
children: [
Positioned.fill(
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Container(
clipBehavior: Clip.hardEdge,
decoration: const ShapeDecoration(
shape: CircleBorder(),
),
child: Image.asset(
'assets/images/image01.png',
fit: BoxFit.cover,
),
),
),
),
///background circle, you also do it on image widget
Container(
decoration: BoxDecoration(
shape: BoxShape.circle,
border: Border.all(width: 5, color: Colors.green),
),
),
Positioned(
top: -12, // half of icon size
left: 0,
right: 0,
child: InkWell(
onTap: () {},
customBorder: const CircleBorder(),
child: Container(
width: 24 12, //icon size padding
height: 24 12,
alignment: Alignment.center,
decoration: const ShapeDecoration(
shape: CircleBorder(),
color: Colors.green,
),
child: Icon(
Icons.add_a_photo,
color: Colors.white,
),
),
),
),
],
),
)
