WHAT IS function and method?

The base class for all function types . The run-time type of a function object is subtype of a function type, and as such, a subtype of Function.

Function — a set of instructions that perform a task. Method — a set of instructions that are associated with an object .

Method and a function are the same, with different terms. A method is a procedure or function in object-oriented programming. A function is a group of reusable code which can be called anywhere in your program . This eliminates the need for writing the same code again and again.

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.
