Introduction to Functions and Methods
Explore the fundamentals of functions and methods in Dart, including how they take inputs, perform operations, and return outputs. Understand the difference between built-in and user-defined functions, learn how to use methods on objects, and see examples like print and indexOf to grasp practical Dart programming concepts.
We'll cover the following...
