SfCartesianChart : _CastError was thrown during paint()

Question

Hi everyone,I integrated syncfusion library on my Flutter App. I've got an issue some times when i navigate into the app and then coming back on the screen where SfCartesianCharts are. They disappear suddenly and never appear again. Is there a way to maintain the state of the paint chart ?I think when the context need to be rebuild the following error appearsflutter: ══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY

Hi Gabriel, 
  
Greetings from Syncfusion. We have analyzed your query and tried to reproduce the reported scenario by navigating from a chart page having spline area series with trendline to a different page and then returned to the chart page. However, the issue is not reproduced at our end. So, kindly provide additional information about the problem or try to reproduce the problem in the sample below and get back to us. This will be more helpful in providing the solution sooner. 
  
Sample: https://www.syncfusion.com/downloads/support/forum/169429/ze/incidents_344441-1805528933 
  
Also ensure with the latest version of our package whether the problem exist or not. We have ensured with the version you have reported, but the reported scenario is not replicated at our end. 
  
https://pub.dev/packages/syncfusion_flutter_charts/versions/19.3.44+1 
  
Thanks, 
Yuvaraj.
