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

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

>Solution :

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.
