Higher-Order Functions
Discover how to work with higher-order functions in Dart by learning to pass functions as parameters, return them as results, and use methods like forEach to handle list operations efficiently. This lesson provides practical examples for applying function-based transformations to lists.
We'll cover the following...
Overview
Dart is a true object-oriented language, so even functions are objects and have a type Function. Functions are treated like first-class values. What this means is that like any other value, a function can be assigned to variables, passed as a parameter to another function, and can also be returned as a result.
Functions that take other functions as parameters or that return functions as results are called higher-order functions.
As Function is another type just like num or List, we can create functions which have parameters of type Function. This means when ...
