How do you write a method in Flutter?

A Dart method is the collection of statements that consists of some characteristics to class object . It provides the facility to perform some operation and it can be invoked by using its name when we need in the program. Methods divide the large task into small chunks and perform the specific operation of that program.

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 .

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 .
