How do you write a method in Flutter?

Why is the build method on State, and not StatefulWidget? Putting a Widget build(BuildContext context) method on State rather than putting a Widget build(BuildContext context, State state) method on StatefulWidget gives developers more flexibility when subclassing StatefulWidget .

It is a method to deliver a project in which the design and construction services are contracted by a single entity known as the design–builder or design–build contractor . It can be subdivided into architect-led design–build (ALDB, sometimes known as designer-led design–build) and contractor-led design–build.

Methods are functions on a class that provide behavior for an object . Instance methods on objects are exposed via instances of the class. They have access to other variables and methods on the instance, as well as the keyword this .
