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.

Preparing your app for deployment

At this point, you may be thinking that you’ve been successfully running your app on simulators, emulators, and devices, so the job is done! From a Flutter point of view, you are virtually ready for production – but there is one piece we need to revisit as a refresher.

Let’s remind ourselves of a couple of Flutter's aims. One key aim is to ensure that app development is optimized for developers as far as possible to ensure the following:

  • Reduce the feedback loop so that developers can see how their changes have changed the app without a lengthy compile time. Hot reloading is an example of this.
  • Have great debugging tools that allow the developer to really understand what is going on within the app. The widget tree in DevTools is an example of this, allowing you to manipulate the widget tree in real time and see exactly how it aligns with your code.

An app framework that can allow these features is likely...
