Flutter： pie_chart 插件动画滚动问题

最后，我把SingleChildScrollView英镑放在了永远不能滚动的物理上.这一定是插件中的错误.

    return SizedBox(
              height: 180.0,
              child: Stack(
                children: [
                  SingleChildScrollView( //<!------in this point
                    physics: const NeverScrollableScrollPhysics(),
                    child: PieChart(
                      baseChartColor: Colors.greyNoEvents,
                      totalValue: hoursSpent,
                      dataMap: dataMap,
                      animationDuration: Duration(milliseconds: 2000),
                      chartLegendSpacing: 22,
                      chartRadius: MediaQuery.of(context).size.width / 3.2,
                      colorList: const [Colors.backgroundGreen],
                      initialAngleInDegree: 0,
                      chartType: ChartType.ring,
                      ringStrokeWidth: 17,
                      centerText: '$subsPercent%',
                      centerTextStyle: const TextStyle(
                          fontWeight: FontWeight.bold,
                          fontFamily: Fonts.satoshi,
                          fontSize: 30),
                      legendOptions: const LegendOptions(
                        showLegends: false,
                      ),

                      chartValuesOptions: const ChartValuesOptions(
                        showChartValueBackground: false,
                        showChartValues: false,
                        showChartValuesInPercentage: true,
                      ),
                      gradientList: gradientList,
                      // gradientList: ---To add gradient colors---
                      // emptyColorGradient: ---Empty Color gradient---
                    ),
                  )
                ],
              ),
        );
      }
