Flutter is Google's UI toolkit for creating beautiful and native applications for mobile, desktop and web from a single Dart codebase. In this book we cover in detail the Dart programming language (version 2.10, with null safety support) and the Flutter framework (version 1.20). While reading the chapters, you'll find a lot of good practices, tips and performance advices to build high quality products. The book is divided in 3 parts. PART 1: It's about the Dart programming language (classes, exceptions, inheritance, null safety, streams, SOLID principles...). PART 2. It's about the Flutter framework (localization, routing, state management with Bloc and Provider, testing, performances with DevTools, animations...). PART 3. It's a long collection of examples (using Firestore, monetizing apps, using gestures, networking, publishing packages at pub.dev, race recognition with ML kits, playing audio and video...). The official website of the book contains the complete source code of the examples and a "Quiz Game" to test your Dart and Flutter skills!

Dart is a modern programming language developed by Google designed to be fast, efficient, and flexible. Flutter is an open-source framework that uses Dart for natively compiling beautiful applications that run on mobile, web, and desktop platforms. Together they offer a robust, streamlined development environment for building high-quality projects. This book is the perfect resource for developers looking to dive into the world of Dart and Flutter to create cutting-edge, cross-platform applications. - The book's first eight chapters are dedicated to Dart 3.0 and all its features. Nothing is given for granted: every aspect of the language is dissected and explained in detail. - We have dedicated over five hundred pages to the Flutter framework. The book covers the widgets basics, the state management solutions, animations, the navigation APIs, and more. - The book has many suggestions and good practices from Dart's and Flutter's official documentation. We have also added recommendations based on the professional experience we have grown over the years. - Theory and simple examples help understand concepts, but seeing the code in action is also very important. We have filled the chapters with examples and comments to help you understand concepts more quickly.

Flutter is a free and open-source mobile UI framework created by Google. There are other tools for the mobile application developers, but Flutter has distinguished it lately for its one single codebase that runs everywhere. If you learn Flutter, with the help of one programming language Dart, and one single codebase you will be able to create two mobile applications, one for Android and the other for iOS.To start with you need to install Flutter that consists of SDK or Software Development Kit and the framework that consists of User Interface libraries based Widget.This book will teach you from the very beginning - how to install Flutter, what IDE you need and above all, how to build your first mobile application.Because Flutter uses Dart programming language, we will start with Flutter, but side by side we will also learn Dart. We will see how Dart programming concepts are implemented in Flutter.Why you will learn Flutter? It is because, Flutter is much simpler to build mobile applications than other available tools.
