这是使用Flutter开发的一个问题charts_flutter。是否有一个参数可将最大值固定在测量轴上？我目前正在desiredTickCount用作骇客，但理想情况下，我只希望3条股票代码（0,5,10）在量度轴上的范围为0-10。

Code snippet:
  Widget _createChart() {
        return new charts.BarChart(
          _createSampleData(),
          animate: true,
          vertical: false,


          primaryMeasureAxis: new charts.NumericAxisSpec(
            tickProviderSpec: new charts.BasicNumericTickProviderSpec(
              desiredTickCount: 11,
            ),
          ),
          barRendererDecorator: new charts.BarLabelDecorator(),
          // Hide domain axis.
          domainAxis:
              new charts.OrdinalAxisSpec(renderSpec: new charts.NoneRenderSpec()),
        );
      }

      static List<charts.Series<OrdinalSales, String>> _createSampleData() {
        final data = [
          new OrdinalSales('Liver', 8),
          new OrdinalSales('Heart', 4),
          new OrdinalSales('Spleen', 5),
          new OrdinalSales('Lung', 1),
          new OrdinalSales('Kidney', 2),
        ];

        return [
          new charts.Series<OrdinalSales, String>(
            id: 'Sales',
            domainFn: (OrdinalSales sales, _) => sales.year, …
