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.

  2. What does ^ at the start of the dependency version mean?
  3. Name the three useful flutter pub commands we explored.
  4. Once you have added the plugin as a dependency and downloaded the code, how do you reference the plugin’s functionality within your code?
  5. For iOS native plugins, can you name the dependency manager they use?
  6. Similarly, for Android native plugins, what build system is used?
  7. How would you clean up your Flutter builds so that you can rebuild afresh?
