How can I provide different coloured plt points on my line graph in charts_flutter

Question

I am creating a line graph in flutter and I would like the points to be different colours or even different icons depending on the position on the measure axis. Is this possible with this package.

The code below is my current Linechart

return new charts.LineChart(
widget.seriesList,
animate: widget.animate,
defaultRenderer: new charts.LineRendererConfig(
includePoints: true,
includeArea: false,
radiusPx: 5,
),
selectionModels: [
new charts.SelectionModelConfig(
type: charts.SelectionModelType.info,
changedListener: (num)=>{
widget.callback(num)
},
)
],
//this is the xaxis
domainAxis: new charts.NumericAxisSpec(
showAxisLine: true,
tickProviderSpec: new charts.BasicNumericTickProviderSpec(
zeroBound: false,
desiredMinTickCount: 12,
desiredMaxTickCount: 12
),
),
primaryMeasureAxis: new charts.NumericAxisSpec(
showAxisLine: true,
tickProviderSpec: new charts.BasicNumericTickProviderSpec(
desiredTickCount: 11,
desiredMinTickCount: 6,
desiredMaxTickCount: 11
),
),
);
