The Dart language is present at the core of the Flutter framework. A modern framework such as Flutter requires a high-level modern language to be capable of providing the best experience to the developer and making it possible to create awesome mobile applications. Understanding Dart is fundamental to working with Flutter; developers need to know the origins of the Dart language, how the community is working on it, its strengths, and why it is the chosen programming language to develop with Flutter. In this chapter, you will review the basics of the Dart language and be provided with some links to resources that can help you on your Flutter journey. You will review Dart built-in types and operators and how Dart works with object-oriented programming (OOP). By understanding what the Dart language provides, you will be able to comfortably experiment with the Dart environment by yourself and expand your knowledge.
