About the Book
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.
We have organized this book in two parts. This part one is meant for absolute beginners. In Part two we will see how we can carry forward our knowledge to known to lesser known facts about Flutter.
In this part of the book, an absolute beginner will learn the language basics of Dart programming, which is extremely important to understand the core Flutter Widget, and Application logic.
With the help of this knowledge we will learn to build a native cross platform mobile application from scratch using Flutter tool.
