@Andrewngabriel Thanks for your hard work on this feature. If you don't mind, though, I'd like you to rework the API to something that more resembles Flutter's material Tab, TabBarView and TabController. I feel that the current API surface is too cumbersome. Setting the content of the body to a particular widget on each tab click, as well as setting the active index, is too much.

• MaosTabView should take a List<Widget> children and a controller used for showing the child based on the index of the widget in the list and the current index of the controller
• MacosTab itself should not be responding to clicks, the controller should be handling that.
• When implemented an API like the above, don't worry about all the animation stuff - we don't need that here.

So.... Is it ready to use? I can't find example code.

@dbsxdbsx No, it is not ready yet. I requested changes to this feature.

Speaking of - @Andrewngabriel are you working on those changes? I could take a crack at it if you're too busy.
