Overview of this book

There have been many attempts at creating frameworks that are truly cross-platform, but most struggle to create a native-like experience at high-performance levels. Flutter achieves this with an elegant design and a wealth of third-party plugins, solidifying its status as the future of mobile app development. If you are a mobile developer who wants to create rich and expressive native apps with the latest Google Flutter framework, this book is for you. You’ll start with the basics of cross-platform development frameworks, specifically Flutter. You’ll then explore the Dart programming language which is the foundation of the Flutter framework. Next, you’ll get a feel for Flutter and how to create your first app, followed by an exploration of the various popular plugins that supplement the Flutter framework. Finally, you’ll explore testing and app release, including some common glitches that you may experience. By the end of this book, you’ll be well-equipped to create and release a basic Flutter app along with gaining a solid understanding of the Flutter framework and Dart language.

Dart Classes and Constructs

In this chapter, we will look at object-oriented programming (OOP) and how this is supported by the Dart language. We will start by looking at the core principles of OOP concerning the Dart language, and then explore how to use OOP within Dart.

We will then take a deeper look at class definitions and how instances of a class are created, including an exploration of the constructor types available, which forms a key part of the way Flutter apps are coded. Additionally, we will look at how we store our code in files, and how to relate code from different files through imports.

Finally, we will look at some key Dart topics that are used throughout Flutter – generics and asynchronous programming. These are important concepts and knowledge of them will help with your understanding of the Flutter topics we will cover later in this book.

On completion of this chapter, you will have a solid foundational knowledge of Dart, which will set you in good...
