Control height of Column within Row - flutter

Question

Trying to get the Column within the Row to take the full height of the Row (as seen in the image)
The Column takes the min height needed but surely there's a way to make it expand the full height of the Row widget? I tried using Expanded but that didn't work.
I want it to take the full height of the Row as then the elements within the Column can be alignment according to mainAxisAlignment: MainAxisAlignment.spaceBetween but at the moment as it takes the min height the elements are all be bunched up together.
return new Container(
child: ListView(
children: <Widget>[
Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Padding(
padding: EdgeInsets.all(20),
child: Text(
client.days[0].dayofLog,
style: TextStyle(
fontSize: 35,
color: Colors.black,
fontWeight: FontWeight.bold),
)),
Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
new AnimatedCircularChart(
key: _chartKey,
size: const Size(300.0, 300.0),
initialChartData: buildGraphElements(client),
chartType: CircularChartType.Radial,
edgeStyle: SegmentEdgeStyle.round,
percentageValues: true,
),
Expanded(
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
new Container(
height: 42.0,
width: 42.0,
color: Colors.red,
),
new Container(
height: 42.0,
width: 42.0,
color: Colors.red,
),
new Container(
height: 42.0,
width: 42.0,
color: Colors.red,
),
new Container(
height: 42.0,
width: 42.0,
color: Colors.red,
),
],
)
)
],
)
],
)
],
));

Try using:
final screenWidth = MediaQuery.of(context).size.width;
final screenHeight = MediaQuery.of(context).size.height;
and at the time of assigning them to your variables you can multiply them by the% of screen you create as necessary.
If possible post a photo with the expected result.
