onChartTouchInteractionDown error

I have an empty onChartTouchInteractionDown callback function but whenever I click on the chart, I get the following error:

Another exception was thrown: Null check operator used on a null value

What could be the cause?

Hi Peter, 
 
Greetings from Syncfusion. We have analyzed your query, and we have tried to reproduce the reported issue in onChartTouchInteractionDown callback, but the scenario is not replicated at our end. Also ensured with all user interaction features available in our chart widget, however the issue didn’t get reproduced. So kindly provide more information about what the properties have you used or try to reproduce the reported issue in the below sample.

Yuvaraj.
