Flutter: Changing the current tab in tab bar view using a button

Question

I am creating an app that contains a tab bar on its homepage. I want to be able to navigate to one of the tabs using my FloatingActio

Answer 1

chemamolin's answer above is correct, but for additional clarification/tip, if you want to call your tabcontroller "from anywhere", also make sure the tabcontroller is not a private property of the class by removing the underscore, otherwise the distant class will not be able to see the tabcontroller with the example provided even when using the GlobalKey.

In other words, change

TabController _tabController;

to:

TabController tabController;

and change

MyApp._myTabbedPageKey.currentState._tabController.animateTo(...);

to:

MyApp._myTabbedPageKey.currentState.tabController.animateTo(...);

and everywhere else you reference tabcontroller.
