Flutter and Dart Cookbook, Rose R., Hajian M., 2023.
    
   Welcome to the Flutter and Dart Cookbook. If you haven’t heard of Flutter, it’s the multiplatform framework that is taking the development community by storm. Dart provides a rich software development kit (SDK) underpinning Flutter. Rather than having to learn multiple technologies, Flutter enables you to target Android, iOS, Linux, the web, and Windows from a single code base.
As someone who watches a lot of YouTube, I am always deeply impressed with the example applications created. Flutter and Dart have been instrumental in not only making me love coding again but also allowing me to meet some awesome Flutter community folks.




Learning Dart Variables.
In this chapter, we focus on learning the basics of using variables in Dart. As you might expect, Dart offers a rich set of variable data types. To quickly get up to speed in the language, it is vitally important to know the basic data types.

If you are familiar with the use of variables in other programming languages, understanding variables in Dart should not be too difficult to grasp. Use this chapter as a quick guide to cement your understanding before moving on to more complex topics.

For beginners, this chapter will introduce you to the fundamentals. Ultimately it should offer a quick technical guide as you progress in your journey to learn Dart/ Flutter.
