How to add a label on pie chart from flutter?

[Kamj Duong]

I wanna users see more information in pie chart (example percent of data, shown in the chart below). 

My code is used show pie chart, i tried some function like displayName, labelAccessorFn in charts.Series but seem label still down show for me.

  @override
  Widget build(BuildContext context) {
    return new charts.PieChart(seriesList,
        animate: animate,
        defaultRenderer: new charts.ArcRendererConfig(arcWidth: 60));
  }

  new charts.Series<LinearSales, int>(
    id: 'Sales',
    domainFn: (LinearSales sales, _) => sales.year,
    measureFn: (LinearSales sales, _) => sales.sales,
    data: data,
  )

I don't think that the drawing code for pie is drawing any text: https://github.com/google/charts/blob/master/charts_flutter/lib/src/canvas/pie_painter.dart.

It might call for a new issue, or it can be a comment in: https://github.com/google/charts/issues/66
