Legend color Doesn't Match Chart Colors

Question

When I set a custom color for pointColorMapper, the colors correctly reflect on the chart; however, the legends never follow the custom colors. Legend colors reflect the default colors (as if I never set any color for the chart and I'm using the default chart's color)Seems like a bug to me.I saw a similar post for a different platform here as well.

Hi Sam, 
  
Greetings from Syncfusion. We have analyzed your requirement. We would like to let you know that when custom color is applied using pointColorMapper, then those color will not be applied to legend and this is our default behavior. You can apply the custom color to legend using the onLegendItemRender event. Find the code snippet to accomplish this. 
  





SfCartesianChart( 
    onLegendItemRender: (LegendRenderArgs args){ 
              if(args.seriesIndex == 0){ 
                args.color = Color.fromRGBO(1, 96, 100, 1); 
              } else { 
                args.color = Color.fromRGBO(239, 108, 0,1); 
              } 
            }, 
)
