How to setstate in one statefulwidget when a button is clicked in another statefulwidget?

Question

So I have one parent statefulwidget that contains a TabBarView. The child to this tabbarview are two different child statefulwidgets.

What I want to achieve is that if I press a button in one of those child statefulwidgets, it should animate the tabcontroller and also set state in the parent statefulwidget.

How to do that? Thanks

You need to create a function in the parent widget which changes the tab and sets the state, and then pass that as a parameter to the children widgets and call it when needed.
