The fastest way to learn programming, in any language or framework is… programming. That's exactly the purpose of this book: helping you learn Flutter by doing.

Flutter is a developer-friendly, open source toolkit created by Google that you can use to create applications for Android and iOS mobile devices, and now also for the web and desktop.

There are eleven projects in this book, covering the main concepts useful to develop real-world apps with Flutter. In each project, you'll learn and immediately use some of the features that make Flutter so successful: widgets, state management, asynchronous programming, using web services, persisting data, animations, creating full-stack applications with Firebase, and even developing responsive apps that work with different form factors, including the web.

Each project builds an app from scratch. You can choose to follow the flow of the book or skip to any project if you feel confident with the concepts introduced in earlier chapters.

Flutter uses Dart as a programming language. In the first chapter, you'll see an introduction to Dart, giving you the necessary knowledge to be productive and create your first Flutter app.

In later chapters, you'll see Flutter projects that go beyond basic examples. You'll get the opportunity to play with code and get hands-on experience building apps. While you progress through this book, you'll see that some of the concepts introduced in earlier chapters are used again, in different ways, on later projects, so that you get deeper knowledge on several topics.
