Abilit to specify a border with different border sides for bar charts.

[dgriffith0]

Currently BarChartRodData only takes a BorderSide and the choices are a full border or no border.

I need to be able to specify a top border only.

I'm intending to work on this issue.
My approach for it is to replace borderSide attribute with another attribute of type Border. This will give the ability to specify each side independently.
This will lead to the possibility of having non-uniform borders. This type of border works when there is no border-radius specified. In other words, the bar is rectangular in shape.
if the bar is a rounded rectangle the borders must be of type uniform borders which can be specified by Border.all() or Border.fromBorderSide().

Hi @MagdyYacoub1

You are exactly correct, do that :)

btw, Flutter does the same about the border radius and non-uniform borders, it throws an exception,
You can check their logic and do the same.
