Widgets in a row not spacing themselves out evenly
I'm trying to make a widget to display posts by users on a social media platform, I have certain elements I want to include in the post, one of them being the external links he might have attached while creating the posts. I want these links to be represented by rounded buttons(which I've managed to achieve through the use of ClipOval) and I want these ovals to be in a row spaced evenly from the center.
So far, the only way I've been able to space them out is by adding SizedBox(s) of a certain width. But this is not efficient for different posts may differ in the number of links and thus the number of Ovals. This would look messy then.
I have overlaid the row on top of the post's image(to which I've applied a linear gradient to make the buttons visible) using a stack.
Here's my code
class postTemplate extends StatelessWidget {
List <String> tags = ['tag1','tag2','tag3','tag4','tag5','tag6','tag7','tag8'];
@override
Widget build(BuildContext context) {
return Scaffold(
body: Column(
children: [
SizedBox(height: 150,),

height: 450,

CircleAvatar(

backgroundImage: AssetImage('assets/Icons/profileLogo.jpg')

}
Any help would be appreciated.
Solution
Wrap with a container and give it full width and remove sizing
Positioned(
bottom: 10.0,
child: Container(
width:MediaQuery.of(context).size.width,
child :Row(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
Container(
width: 56,
decoration: BoxDecoration(
shape: BoxShape.circle,
boxShadow: [
BoxShadow(
color: Colors.black,
blurRadius: 2.0,
spreadRadius: 1.0,
)
]
),
child: ClipOval(
child: Material(// button color
child: InkWell(
splashColor: Colors.red, // inkwell color
child: SizedBox(width: 56, height: 56, child:Image(
image: new AssetImage("assets/Icons/browser.jpg"),
width: 32,
height:32,
color: null,
fit: BoxFit.scaleDown,
),),
onTap: () {},
),
),
),
),
Container(
width: 60,
decoration: BoxDecoration(

boxShadow: [
