Functions in Dart - Learn About Functions, Closures and Different Types of Parameters in Dart

This video is part of the Dart Crash Course playlist on YouTube. See the entire playlist here:    • Dart Crash Course  

Welcome to Dart Crash Course. Dart is a beautiful and modern programming language that can be used both for frontend and backend applications. In this course, we will focus on Dart as a programming language without blending in any other frameworks such as Flutter.

In this video we will have a look at functions and different types of return values and parameters/arguments that can be passed to them. We will also look at inline functions, which are also sometimes referred to as closures in other languages and how functions are first-class citizens in Dart.
