How can I use a method of state class in any another state class of same Project?

Question

I have a long method in a State class which I want to use in any other state class. So How can I do such that ?

Answer 1

you can pass that method to the other class constructor. for example:

class ContainingMethod() {

MethodTaker(method)

method() {
...
}

}

// The class which method is passed to 

class MethodTaker {
final method;
MethodTaker(this.method)
}

Answer 2

you probably want to understand state management. By reading a little further into your question, I'd say you want to study and implement the Provider package.
