3 weeks ago Hi @mahdiqdi,
The reported issue is already fixed and rolled out in our weekly patch release. Therefore, we kindly request that you upgrade the syncfusion_flutter_charts package to the latest version below to avoid this issue.
Version: https://pub.dev/packages/syncfusion_flutter_charts/versions/25.1.41+1
Root cause: Missed to ensure the length of the trackball info list before getting a list of index values.
Regards, Lokesh P.
