SfCartesianChart FastLine Series updateDataSource issue

Hi,

I came across a forum suggestion of integration FastLineSeries instead of LineSeries for improving performance and some tweaks to improve the zooming and scrolling experience. 

[ SfChart ] Big Data sample | Flutter Forums | Syncfusion..

When tried to integrate the same in Flutter, found 

antialiasing , SuspendSeriesNotification method, and some features mentioned were unavailable in Flutter when compared to the Xamarin ref. shared in the forum.

Also the dynamic updation of points using chartSeriesController.updateDataSource() is not being reflected when using the FastLineSeries. It worked perfect when used LineSeries.

Can I get some example/docs to integrate the same in flutter.

Looking forward to hear you back.

Aswin.
