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.

Questions

This chapter was mainly provided to make you aware of the tools and techniques that are available to you, rather than any specific knowledge that needs to be retained, so use these questions as a way to check your awareness:

  1. Why would you write a unit test?
  2. What method would you call to check that the outcome of a test matches the expectation?
  3. Describe the concept of mocking when testing code.
  4. Which class would you use to test a widget?
  5. There are two ways to set a debugger breakpoint – one in the IDE and one in code. Can you remember how to do this?
  6. We looked at two inspectors within DevTools. Can you remember how to open them in your IDE and what their purposes are?
  7. A cheeky bonus question – Flutter has traditionally used the Skia graphics library for rendering, but can you name the new rendering library that Flutter is transitioning to?
