DecorationImage/Image as Child going outside of Container? - image

Question

I have tried these
1. DecorationImage
2. Image
3. CircleAvatar
I have used Stack as there will be a background image.
But I am not able to understand why the image is expanding like that.
I need a circular image for the profile pic.
If I use Column instead of ListView then the images doesn't expand like this ...but I need a ListView.
The code:-
#override
Widget build(BuildContext context) {
return Scaffold(
body: Stack(
children: <Widget>[
ListView(
children: <Widget>[
Padding(
padding: const EdgeInsets.all(8.0),
child: Container(
height: 80.0,
width: 80.0,
decoration: BoxDecoration(
shape: BoxShape.circle,
image: new DecorationImage(
image: AssetImage(Assets.cool),
fit: BoxFit.cover,
),
color: Colors.red,
),
),
),
Padding(
padding: const EdgeInsets.all(8.0),
child: Container(
height: 50.0,
width: 50.0,
decoration: BoxDecoration(
shape: BoxShape.circle,
),
child: Image(
image: AssetImage(Assets.cool),
fit: BoxFit.cover,
),
),
),
Padding(
padding: const EdgeInsets.all(8.0),
child: CircleAvatar(
radius: 50.0,
backgroundImage: AssetImage(Assets.cool),
),
)
],
)
],
),
);
}

Answer 1

From my understanding you want the image in a circle not a ellipse. You can achieve that by wrapping the items in your listview with a Row element.
return Scaffold(
body: Stack(
children: <Widget>[
ListView(
children: <Widget>[
// Wrap with a row
Row(
children: <Widget>[
Padding(
padding: const EdgeInsets.all(8.0),
child: Container(
height: 80.0,
width: 80.0,
decoration: BoxDecoration(
shape: BoxShape.circle,
image: new DecorationImage(
image: AssetImage("a.jpg"),
fit: BoxFit.cover,
),
color: Colors.red,
),
),
),
//...
],
),
],
)
],
),
);

To get a circular image, Just wrap all your widget of ListView in a Column widget and place the Column in ListView. You'll get a scrollable column.
ListView(
children: <Widget>[
Column(
children: <Widget>[
Padding(
padding: const EdgeInsets.all(8.0),
child: Container(
height: 80.0,
width: 80.0,
decoration: BoxDecoration(
shape: BoxShape.circle,
image: new DecorationImage(
image: AssetImage(Assets.cool),
fit: BoxFit.cover,
),
color: Colors.red,
),
),
),
//.....
],
)
],
),s
