Hi!

I'll take a look ok?

About:

the width of the tabsArea is equal to the width of the tabs

The tab area is inside a parent container. So its width is the maximum size. To achieve the same visual effect as the image, it would be necessary to have an internal container in the tab area. However, this area may have extra buttons that must always be visible in the corner.

If you will always have a fixed number of tabs and if they are centered, they do not exceed the full width. So maybe Flutter's tab widgets (eg TabBar) are enough.

Why not provide a "tabsArea.decoration" instead of border and color, it will be more flexible.

Also, I see you already use decoration at multiple places, but not yet there. It will be helpful to improve the styling.

(Also integrate the last version in your docking component will be great)

Thx
