I am trying to use tab controller in flutter how can I access it inside the build context

Question

I am trying to use a tab bar controller , what is the right way to add it

Answer 1

Just declare the tabController globally inside your state class and initialise it inside init state as you did, then you can access it inside your build method.

late TabController tabController;

void initState(){
   tabController=TabController(vsync:this,length:3); 
}
 

now use accordingly tab controller inside build method.

Answer 2

Try to declare tabController globally inside your state class and init it inside init state see the documentation for more details :

class _JobApplication... extendes State<...> ..{

   late TabController _tabController;

  @override
  void initState() {
    super.initState();
    _tabController = TabController(vsync: this, length: 3);
  }

}

Answer 3

declare in state

late TabController _tabController;

Assign in initstate

@override
  void initState() {
    super.initState();
    _tabController = TabController(vsync: this, length: 3);
  }
