如何在flutter饼图中实现标签上的onClick？

Question

我正在使用 Charts_flutter 库库显示PIECHART。我试图实现的是，当您点击图表的一部分或关联的标签（在外面呈现）时，它会导航到页面。我已经找到了方法，选择了Piechart的一部分并相应地导航，但是由于图中有非常苗条的部分，因此几乎不可能单击它们，因此我需要能够单击其标签，并且仍然导航。这可能吗？

final rendererConfig = charts.ArcRendererConfig(arcWidth: 65, arcRendererDecorators: [
      charts.ArcLabelDecorator(
          insideLabelStyleSpec: const charts.TextStyleSpec(fontSize: 12, color: charts.Color.black), labelPosition: charts.ArcLabelPosition.outside)
    ]);

List<charts.Series<CropSeries, String>> series = [
      charts.Series(
        id: "PieChart",
        data: data,
        domainFn: (CropSeries series, _) => series.name,
        measureFn: (CropSeries series, _) => series.totalArea,
        colorFn: (CropSeries series, _) => series.color,
        labelAccessorFn: (CropSeries series, _) => '${series.name}: ${numberFormat.format(series.totalArea)} ${series.areaUnit}',
      )
    ];

return charts.PieChart(series, animate: true, defaultRenderer: rendererConfig, selectionModels: [
              charts.SelectionModelConfig(
                changedListener: (SelectionModel model) {
                  if (model.hasDatumSelection) {
                    String cropRotation = model.selectedSeries.first.domainFn(model.selectedDatum.first.index);

                    Navigator.push(
                      context,
                      MaterialPageRoute(
                        builder: (context) => VarietyRotationScreen(cropRotationName: cropRotation),
                      ),
                    );
                  }
                },
              )
            ]);
