BarChart: Is there a possibility to "shrinkWrap" the chart?

Hi,

at the moment, the BarChart seems to use any available horizontal space.

Is there a possibility to turn this around, so it draws the horizontal size it requires, but not more?

I'm trying to implement this chart (screenshot from Figma):

My current achievement looks like this:

As you can see the horizontal lines span the full available width. The axis is also separated from the chart due to that.

I want to use the `groupSpace` so I can define the space between each group. Any other placement is not what I need.

So, the issue is, that the chart uses more space than it actually needs.

Is there a way to render it only in the size it really needs, or do I need to calculate that beforehand and put the chart into a `SizedBox`?

Start with the BarChart widget and the groupSpace behavior described in the issue. Determine how the chart currently sizes its horizontal content and define a supported way for it to use only the required width while preserving group spacing and aligned axes.
