BarSeries<T, D> class Null safety

This class has the properties of the bar series.

To render a bar chart, create an instance of BarSeries, and add it to the series collection property of SfCartesianChart. The bar series are rectangular bars with heights or lengths proportional to their represented values.It has the property of spacing to provide spacing between bars.

Provides options for color, opacity, border color and border width to customize the appearance.
