onMarkerRender for scatterplot throwing error when zooming in

Im using flutter web.

When I create a scatterplot that has an onmarkerrender call on it like this:

SfCartesianChart(
    onMarkerRender: (args) {

}

It throws this error when I zoom in: IF i take the empty function away it zooms fine. This is most definitely a bug.


The following IndexError was thrown during paint():

RangeError (index): Index out of range: no indices are valid: 0


The relevant error-causing widget was:

  SfCartesianChart SfCartesianChart:file:///C:/Users/TWK463/StudioProjects/iot_dashboard%20-%20PreHTTP-Firebase/lib/stationDataCharts.dart:175:18
