making the circular avatar show at the top of the screen - flutter

How can I make the circleavatar to be placed at the top of the container


you can use Stack for this. like:
...
return Stack(
children: [
Positioned.filled( child:
Scaffold(
appBar: ...
body: Column([
DecoratedBox(
...
)
]),
)),
Positioned(
top: 24,
child:
CircleAvatar( child:
CachedNetworkImage(
...
),
),
),
],
);
something like that.


Try below code hope its helpful to you.refer Stack class here
Stack(
alignment: Alignment.topCenter,
children: <Widget>[
Padding(
padding: EdgeInsets.only(top: 21),
child: Container(
height: 200,
width: double.infinity,
child: Card(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(20),
),
color: Colors.white,
margin: EdgeInsets.all(
16,
),
),
),
),
Container(
width: 100,
height: 90,
decoration: ShapeDecoration(
shape: CircleBorder(),
color: Colors.transparent,
),
child: CircleAvatar(),
)
],
),

Flutter how to create circular border around icon and align an image top of the circular border

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.

Default clipBehavior on Stack is hardEdge.
Use clipBehavior: Clip.none on Stack.
And to have circle shape
use customBorder: CircleBorder(), on InkWell.
use shape: BoxShape.circle instead 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,
),
),
),
),
],
),
)
Play with sizes and decoration

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,

Thanks all for the contribution but here is what works perfectly for what I'm looking at. I added clipBehavior and set Clip to noneclipBehavior: Clip.none, added ClipOval in a Container and set it margin and padding respectively to give the space between the green circular border and the profile image. I also, added another Container inside my ClipOval so as to add my image as a child to it. Find below my final code:
Center(
child: Stack(
clipBehavior: Clip.none,
children: [
CircleAvatar(
radius: 60,
backgroundColor: colorGreen,
child:Container(
padding: EdgeInsets.all(4),
margin: EdgeInsets.all(3),
decoration: BoxDecoration(
color: Colors.white,
shape: BoxShape.circle,
),
child: ClipOval(
child: Container(
height: 250,
width: 250,
child: Image.network(
'my image link',
fit: BoxFit.cover,
),
),
)
)),
Positioned(
bottom: 100,
right: 45,
child: InkWell(
onTap: () {},
child: Center(
child: CircleAvatar(
backgroundColor: colorGreen,
radius: 15.0,
child: Icon(
Icons.check,
color: Colors.white,

how to position an image on top of another "card"?

This is my first time here
I face a little problem which is the image that I wanted to put on top of the card do not work properly, the rest of it didn't display
I used (stack & positioned)
What should I do ??
Note : I'm beginner 👀
this is the code :
SizedBox(
width: 500,
height: 100,
child: Container(
child: Padding(
padding:
EdgeInsets.symmetric(horizontal: 10, vertical: 10),
child: Card(
color: Colors.grey.shade400,
child: Stack(children: [
Positioned(
bottom: 40,
left: 150,
child: CircleAvatar(
child: ClipOval(
child: Image.asset(
"assets/images/guy.jpg",
width: 100,
height: 100,
fit: BoxFit.cover,
),
),
backgroundColor: Colors.transparent,
radius: 50,
),
),
]),
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(15),
),
elevation: 10),
),
)),
and this is the the output :
enter image description here
and i wanted to be like this : enter image description here

if you want like that, then you need to put SizedBox and add size (height and or width) on it it acts as invicible widget to put space on it.
Stack
--Positioned (top 0)
----Column
------SizedBox (add height here around 50x50 px)
------Image (100x100 px)
--Card

Try below code hope its helpful to you. refer for thar Stack class here

you can use following code sample...change height according to your need...or use mediaquery for better result:
Container(
height: 275,
child: Stack(
children: [
Container(//container with background color
height: 250,
child: //other widgets
),
Positioned(

As you can see, i'm using a lot of repeated Stack widget manually.
Can I make that automated? like creating a Stack widget or something similar once, and then call it where it should be with different Title.
Regards, Slim

It is indeed possible, this is what we call a reusable widget.
You can create it in the same file or in a separate one. I would suggest creating a widgets folder containing a dart file (whatever you want to name it) that'll contain your reusable widget.
1- If you only want the title to be different each time it should be something like this:
class SpecialStack extends StatelessWidget{
final String title;
SpecialStack({this.title});
#override
Widget build(BuildContext context){
return Stack(
children: <Widget>[
Container(
height: double.infinity,
width: double.infinity,
child: ClipRRect(
borderRadius: BorderRadius.circular(10),
child: Hero(
tag: 'Image2',
child: Image.asset(
"assets/images/gallery/Image2.jpg",
fit: BoxFit.fitHeight),
),
),
),
Container(
padding: const EdgeInsets.all(5),
child: ClipRRect(
borderRadius: BorderRadius.circular(10),
child: Text(title,
style: TextStyle(
backgroundColor: Colors.deepOrange,
color: Colors.white)),
),
)
],
),
}
}
2- If you want the image to be different whenever you use your reusable widget, it should be something like this. (I provided this case because I saw you were using different image for each Stack):
class SpecialStack extends StatelessWidget{
final String title, image;
SpecialStack({this.title, this.image});
#override
Widget build(BuildContext context){
return Stack(
children: <Widget>[
Container(
height: double.infinity,
width: double.infinity,
child: ClipRRect(
borderRadius: BorderRadius.circular(10),
child: Hero(
tag: image,
child: Image.asset(
"assets/images/gallery/$image.jpg",
fit: BoxFit.fitHeight),
),
),
),
Container(
padding: const EdgeInsets.all(5),
child: ClipRRect(
borderRadius: BorderRadius.circular(10),
child: Text(title,
style: TextStyle(
backgroundColor: Colors.deepOrange,
color: Colors.white)),
),
)
],
),
}
}
For the first case (only title is different),
You can just replace wherever you're using the Stack by this:
SpecialStack(title: "Your desired title")
For the second case (image and title are different):
SpecialStack(title: "Your desired title", image: "your_image_name")
I hope this helps. I tried to be as clear as possible.

keep your images in a list then map the list. and inside map define a Stack widget. it will automatically create the stacks of your list of images.

You should write one function return widget type. Every time you want to show image you can call it.
Ex
Widget showImage(String url, String text){
return Stack(
children: <Widget>[
Container(
height: double.infinity,
width: double.infinity,
child: ClipRRect(
borderRadius: BorderRadius.circular(10),
child: Hero(
tag: 'Image8',
child: Image.asset(
"url,
fit: BoxFit.fitHeight),
),
),
),
Container(
padding: const EdgeInsets.all(5),
child: ClipRRect(
borderRadius: BorderRadius.circular(10),
child: Text(text,
style: TextStyle(
backgroundColor: Colors.deepOrange,
color: Colors.white)),
),
)
],
),
}
