Flutter Network Image does not fit in Circular Avatar

I am trying to retrieve bunch of images from an api. I want the images to be displayed in Circular form so I am using CircleAvatar Widget, but I keep getting images in square format. Here is a screenshot of images

enter image description here

Here is the code I am using

ListTile(leading: CircleAvatar(child: Image.network("${snapshot.data.hitsList[index].previewUrl}",fit: BoxFit.scaleDown,)),),

I tryied using all the properties of BoxFit like cover, contain,fitWidth,fitHeight etc but none of them works.

This Will Work : You need to use backgroundImage:property in order to fit it in Circle.

CircleAvatar(
radius: 30.0,
backgroundImage:
NetworkImage("${snapshot.data.hitsList[index].previewUrl}"),
backgroundColor: Colors.transparent,
)

To Check with Dummy Placeholder:

CircleAvatar(
radius: 30.0,
backgroundImage:
NetworkImage('https://via.placeholder.com/150'),
backgroundColor: Colors.transparent,
)

Had a similar problem in the AppBar actions widget list.

This worked for me:

CircleAvatar(
radius: 18,
child: ClipOval(
child: Image.network(
'image-url',
),
),
),

If you don't want to use CircleAvatar, here is how you can do it. 

ClipOval(
child: Image.network(
'https://via.placeholder.com/150',
width: 100,
height: 100,
fit: BoxFit.cover,
),
),

Here is a round picture with a shadow:

child: AspectRatio(
aspectRatio: 1/1,
child: Container(
margin: EdgeInsets.all(
10.0
),
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(100.0),
boxShadow:[
BoxShadow(
color: Color.fromARGB(60, 0, 0, 0),
blurRadius: 5.0,
offset: Offset(5.0, 5.0)
)
],
image: DecorationImage(
fit: BoxFit.cover,
image: NetworkImage(user.image)
)
)
)
)

  ClipOval(
child: Image.asset(
'assets/dummy.jpg',
fit: BoxFit.contain,
matchTextDirection: true,
height: 50,
))

Use combination of width/height, fit and wrap image in ClipOval like below:

CircleAvatar(
child: ClipOval(
child: Image.network(
_photo,
width: 120,
fit: BoxFit.fill
),
),
radius: 50,
),

I had the same problem

CircleAvatar(
radius: 30.0,
backgroundImage: NetworkImage(imageURL),
backgroundColor: Colors.transparent,
));

fixed my issue.

Came here as I also had the issue with CirclAvatar and AppBar, where the image would stretch in height. Instead of a radius, as I'm not able to provide it with the component I'm using, I just wrapped the image with a colum when used in appbar. This makes the image not stretch in height. This way I can always control size from the outside too

Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
SizedBox(height: 40, width: 40, child: ProfileBadge(),),
],
)

this work for me

   CircleAvatar(
child:  ClipRRect(
borderRadius: new BorderRadius.circular(100.0),
child:Image.network("http://www.rd.com/wp-content/uploads/2017/09/01-shutterstock_476340928-Irina-Bg-1024x683.jpg"),
),),

If you want to show your image covering whole width of circle avatar then you can use it like this way. And if your image didnot load then it will show default person icon. 

 CircleAvatar(
child: ClipOval(
child: Center(
child: _image == null
? Icon(
Icons.person,
color: Colors.grey.shade700,
size: 100,
)
: Image.file(
_image,
fit: BoxFit.cover,
width: MediaQuery.of(context).size.width,
),
),
),


radius: 50,
backgroundColor: Colors.grey.shade300,
),

You will need to use NetworkImage, AssetImage, FileImage, MemoryImage or something similar. You can't directly use Image.network, Image.asset or similar due to how Flutter architects its image classes.

An example:

CircleAvatar(
radius: 100.0,
backgroundImage: NetworkImage(...),
)

backgroundImage in CircleAvatar expects to receive an ImageProvider as a parameter. However, Image.network and others don't directly extend the ImageProvider class, they merely extend the StatefulWidget class, even though they use NetworkImage inside. That is why you see in the other answers that ClipOval or ClipRRect is being used. These classes accept a Widget and so they're not as particular as CircleAvatar and similar classes are.

Instead of these workarounds, therefore, for CircleAvatar, you should use NetworkImage and similar classes and for widgets that expect just a Widget, you can use Image.network and similar.

Another reason not to use clips is that they can be more expensive than changing the border radii directly: https://flutter.dev/docs/perf/rendering/best-practices

if someone intends to create bordered circular image try this.

Using ClipOval widget is not perfect solution because if images are not square result will be elliptic. 

CircleAvatar(radius: (52),
backgroundColor: Colors.white,
child: ClipRRect(
borderRadius:BorderRadius.circular(50),
child: Image.asset("assets/pictures/profile.png"),
)
)

ClipRRect widget prevents image to overflow CircleAvatar widget.

I had the same problem. Using clipoval in circle avatar will make it elliptical. But this fixed this issue.

CircleAvatar(


radius:25.0,


backgroundImage: NetworkImage(
'${image_url}',




),
backgroundColor: Colors.blue,
),
小开 
 CircleAvatar(
radius: 26,
backgroundColor: Colors.white,
child: ClipOval(
child: _bytesImage == null
? new Text('No image value.')
: Image.memory(
_bytesImage,
width: 60,
height: 60,
fit: BoxFit.cover,
),
),
),

It took a few tries to figure this one out.. All these answers did not help me. In the end picture that I inserted into the circle avatar was stretched out to the boundaries of the container that was 2 instances above it. Maybe there are are people who, after going through the answers here, still have the problem that I had. I solved the constraint issue with a FittedBox

             GestureDetector(
onTap: () => getImage(),
child: Container(
width: MediaQuery.of(context).size.width,
decoration: BoxDecoration(
color: Colors.orange,
),
//padding: EdgeInsets.fromLTRB(0.0, 0.0, 0.0, 0.0),
child: Container(
width: 140,
height: 160,
child: FittedBox(
child: picture(),
)),
),
),

This is the code for the picture() that I use. I think that the container inside the picture() is not necessary anymore, try it yourself :)

Widget picture() {
if (_image == null) {
return CircleAvatar(
radius: 70,
child: Icon(
Icons.person,
size: 150,
color: Colors.grey[900],
));
} else {
return Container(
width: 140,
height: 140,
child: CircleAvatar(
radius: 70,
backgroundImage: FileImage(_image),
),
);
}

in this solution you can resize the image by container and clip image by clip Oval then add shadow to the image by card.

Container(
width: 100,
height: 100,
child: InkWell(
onTap: () {},
child: Card(
elevation: 5,
shape: RoundedRectangleBorder(
side: BorderSide(color: Colors.grey),
borderRadius: const BorderRadius.all(
Radius.circular(45.0),
),
),
child: Container(
child: ClipOval(
child: CachedNetworkImage(
imageUrl: '{image-url}',
imageBuilder: (context, imageProvider) => Container(
decoration: BoxDecoration(
image: DecorationImage(
image: imageProvider,
fit: BoxFit.fill,
),
),
),
placeholder: (context, url) => Container(
height: 5,
width: 5,
child: CircularProgressIndicator(
valueColor: AlwaysStoppedAnimation<Color>(Colors.blue),
),
),
errorWidget: (context, url, error) => Icon(Icons.error),
)),
),
),
));

If anyone is trying to fit a circular image in app bar actions. Try below solution it should work.

         Padding(
padding: const EdgeInsets.all(8.0),
child: AspectRatio(
aspectRatio: 1,
child: CircleAvatar(
backgroundImage: NetworkImage('https://picsum.photos/seed/picsum/200/500'),


),
),
)

AspectRatio first tries the largest width permitted by the layout constraints(here the appbar). If I remove the padding image radius will be of appbar size. So add padding to control the size of circular image.

simply use backgroundImage inside CircleAvatar

 CircleAvatar(
backgroundImage: AssetImage("assets/images/dia.jpg",),
),
小开 
Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
GestureDetector(

MaterialPageRoute(builder: (context) => MyApp7()),
);
},
child: CircleAvatar(
radius: 50,
// backgroundColor: Colors.amber,
child: CircleAvatar(
backgroundColor: Colors.grey[50],
radius: 50,
// child: Image.asset("assets/images/nophotoMale.png")
backgroundImage:
AssetImage("assets/images/nophotoMale.png")),
),

Wrap your CircleAvatar widget under Stack widget.

 return Stack(
children: [
CircleAvatar(
radius: 50.0,
backgroundImage: NetworkImage(
'https://i.pinimg.com/474x/0c/eb/c3/0cebc3e2a01fe5abcff9f68e9d2a06e4.jpg'),
),
],
);

this worked for me

Transform.scale(
scale: 0.6,
child: ClipOval(
child: Image.network(
<IMAGE URL HERE>,
),
),
)

Use AvatarView lib https://pub.dev/packages/avatar_view which provides the functionality to show network/asset images in circular/rectangular form.

To use add below dependency

dependencies:
avatar_view: ^1.0.0+3

Example:

        AvatarView(
radius: 60,
borderColor: Colors.yellow,
avatarType: AvatarType.CIRCLE,
backgroundColor: Colors.red,
imagePath:
"https://images.pexels.com/photos/415829/pexels-photo-415829.jpeg?cs=srgb&dl=pexels-pixabay-415829.jpg",
placeHolder: Container(
child: Icon(Icons.person, size: 50,),
),
errorWidget: Container(
child: Icon(Icons.error, size: 50,),
),
),

It also provide funtionality to add borders around widget, for more example visit above link

Output:

Below worked in my case:

literally I tried every mentioned solution in this page and nothing works as I want using CachednetworkImgaeProvider or NetWorkImage works but when error occurs this cause code unhandled exception, and can't use a dummy image as error image, after some work I found an acceptable solution with some extra work using StatefulBuilder widget as below note: you need to define global bool in order to work as the solution in the picture my code example in the picture and my global bool is (_isError)

hope you like this solution
