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.

When you develop an app, working on frontend graphics can be the most rewarding because your stakeholders, testers, and users get to see your progress with you. Let’s recap some of the knowledge gained from this chapter so that, as you develop your apps, this knowledge comes easily to you:

  1. What’s the difference between 6-digit and 8-digit hex colors?
  2. Why would you use the overflow parameter of the TextStyle constructor?
  3. What would you use BoxDecoration for on a container?
  4. Do you remember why you need a global key when working with drawers on scaffolds?
  5. Which inherited widget do you require to display a snackbar to a user?
  6. Can you remember which image types are supported by Flutter? For bonus points, can you remember the two additional image types we discussed?
  7. Which slivers did we use in our example?
