Cannot set the name of axis?

[Flynn2018]

Now using fl_chart: ^0.60.0 to create one bar chart, but cannot set the name of axis due to "The named parameter 'axisTitleData' isn't defined."?

return BarChart( BarChartData( maxY: 25,

    axisTitleData: FlAxisTitleData( **//The method 'FlAxisTitleData' isn't defined for the type 'BarChartPageState'.**
      show: true,
      leftTitle: AxisTitle( **//The method 'AxisTitle' isn't defined for the type 'BarChartPageState'.**
        titleText: "Interest Rate",
        showTitle: true,
        textStyle: TextStyle(fontSize: 15, color: Colors.white),
      ),
      bottomTitle: AxisTitle(
        titleText: "Banks",
        showTitle: true,
        textStyle: TextStyle(fontSize: 15, color: Colors.white),
      ),
    ),
