Hi Mohammad ghawanmeh,

The requirement can be achieved by using the plotBands property in the primaryYAxis, its always visible in chart. We have used the plotBands property and set the start and end properties value to 28 as per the below code snippet. 

Code snippet:

primaryYAxis: NumericAxis(

......

            plotBands: [

              PlotBand(

                start: 28,

                end: 28,

                borderWidth: 2,

                borderColor: Colors.blue,

                dashArray: const [5, 5],

              ),

            ],

          ),

Kindly refer to the attached UG document regarding PlotBand for further information.

And we have attached a sample below for your reference. 

Thanks,
