Height adjustment of an Image in a row inside a Card - flutter

Question

my idea is to create a card widget that has an image on the left and corresponding text data on the right side. The picture should always take the full height and 1/3 of the width (I used expanded with flex to get this. Not sure if this is the best way). The image should be placed in a stack in order to stack further widgets.
My problem is that I am not able to place the image in the stack without specifying a fixed height. I tried Positoned.fill but this did not work for me.
This is my code so far for the card:
Widget build(BuildContext context) {
return Card(
elevation: 5,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(15.0),
),
child: Row(
children: [
Expanded(
child: Stack(
children: [
Container(
// child: Positioned.fill(
// child: ClipRRect(
// borderRadius: BorderRadius.circular(15.0),
// child: Image(
// image: AssetImage("assets/eyes.jpg"),
// fit: BoxFit.cover,
// ),
// ),
// ),
),
],
),
),
Expanded(
flex: 2,
child: Container(
color: Colors.grey,
child: Padding(
padding:
const EdgeInsets.symmetric(horizontal: 15.0, vertical: 10),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text("This is a test"),
SizedBox(height: 10),
Text("This is a test test"),
SizedBox(height: 10),
Text("This is a test test test"),
SizedBox(height: 10),
Text("This is a test test"),
SizedBox(height: 10),
Text("This is a test"),
],
),
),
),
),
],
),
);
}
Here is a picture of the current state. The image should take up the entire white area on the left side of the card.

Instead of adding a child image widget inside your container, you can add a decoration image to the container itself. Here's how you do it:
Container(
decoration: BoxDecoration(
image: DecorationImage(
fit: BoxFit.cover,
image: AssetImage("url"),
),
),
),
