Add ScrollPhysics support in tabs scroll

[andychucs]

Is it possible to add ScrollPhysics support?

I've noticed that after setting tabMinLength to allow tabs to scroll, the effect doesn't appear smooth, and it's difficult to achieve accurate and fast swiping. I looked into the related code, and it seems that this package directly handles touch events on the tabs.

Is it possible to implement scrollable tabs like this ScrollView -> IntrinsicHeight -> "TabsWidget"?

Or by handling the scroll position in handleEvent with ScrollController.createScrollPosition, we could define physics; using BouncingScrollPhysics by default on iOS would make the component's motion appear smoother.

I'm not yet familiar enough with the code of this package, sorry that I cannot submit a PR at the moment. If possible, could you check if the methods I mentioned could be implemented, or could you tell me how I should modify it?
