SelectionIndex method in selectionSettings

[Jason]

The SelectionSettings selection.selectedIndex() method currently has no effect for circular charts. It does work for cartesian charts and you can programmatically select a bar, for example.

The example at https://help.syncfusion.com/flutter/circular-charts/methods has several typos in it, but when corrected, the function fails silently and has no effect. It looks like the issue is that _selectionRenderer in selection.dart is NULL for circular charts and so the selectedIndex() function essentially does nothing.

Hi Jason, 

  

Greetings from Syncfusion. We have analyzed your scenario and we are sorry to inform to you that there has been a mistake in our UG documentation regarding circular chart selection public methods section. Currently, there is no support for public selection methods in the circular chart. However, we have considered this as a feature request and created feedback for it in our feedback portal. We will include this feature in our upcoming vol 2 SP 1 release. We will update you once the release is rolled out and we appreciate your patience until then.
