Extensions in Dart - Learn How to Extend the Functionality of New and Existing Types with Extensions

Video Description

This video is part of the Dart Crash Course playlist on YouTube. See the entire playlist here: https://www.youtube.com/playlist?list=PL6yRaaP0WPkVLSOchfoIA0ZXySz4eSYV2 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 creating extensions that can help us write better code, on existing and new data types. This chapter blends in the concept of extensions together with generics so I highly recommend that you watch the previous chapters first, specifically the chapters about generics and collections.
