Change bars' styles when using AnimatedBarSeries and AnimatedBarStack

[nicolasst22]

is there any way to change the style of the bars when using Animated bar series and animated bar stack?
I'd like to customize bars

set a custom bar width
set a gap between bars in the stack.
Maybe it could be done passing children to the componentes, but I haven't found any example. The examples are always using the most primitives components.

I attached an example of how I want it to looks like

Thank you in advance
