The main advantage of this Book is it will upgrade with Flutter. It is at an advantage because I regularly write Flutter blog at my website https://sanjibsinha.com, and as a result, I always keep adding those posts in new chapters, so that you can update your knowledge from lesser known facts to unknown facts about Flutter.

Consequently the pages and words have been increasing since I have first published this book. Finally, where it will stop? I can't assume at present, the pages might cross two thousand or more, because in every month "Beginning Flutter with Dart" will get updated twice or thrice. Therefore once you've got the book, it will always give you the most recent development that takes place in Flutter widget and user interface world.

In addition, as you progress, you'll find that more concise and succinct detail about the Flutter widgets, and besides, inherent concepts regarding widgets are getting added in a regular basis. I hope, that'll help you to understand firstly, and secondly, build more robust Flutter applications.

For example, although in the first part we used old Provider package, we've updated that to the new version in the later section.

As you know, Flutter is a free and open-source mobile User Interface framework created by Google. Therefore, it doesn't cost you any money to build and test applications.

There are other tools for the mobile application developers. But Flutter has distinguished itself for its simplicity.

Moreover, Flutter has one single codebase that runs everywhere.

By the way, Flutter uses on programming language in the background – Dart.

Therefore, if you’re a beginner and want to learn Flutter from scratch, you must have a knowledge of Dart, as well. And, this book will help you to achieve this.

Now, if you learn Flutter, with the help of one programming language Dart, you will be able to create two mobile applications at the same time.

One for Android and the other for iOS.

However, to start with you need to install Flutter that consists of SDK or Software Development Kit.

In addition, the Flutter framework that consists of User Interface library based Widget will help you to build any design you want to do.

This book will teach you from the very beginning. How to install Flutter, what IDE you need. 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 and its implementation on Flutter.

As time passes by, we’ll keep updating this book as Flutter gets upgraded, adding new features. Moreover, you’ll learn them also in this book.

If I say, StafulWidget in Flutter is actually a StatelessWidget, you'll get confused!


If I had said, stateful widget didn't make any sense, either you wouldn't have agreed, or you would have got more confused!

Hope this book will help you to be a Better Flutter Developer who can manage state and make her Flutter App more performant. However, for state management always use the latest Provider Package, and maintain Null Safety.

I also strongly recommend to read the latest Flutter blog at my website.

Let me tell you the truth. The stateful widget, although might come to help for a tiny app where we need to change a single class property, doesn't really make any sense for a big, complex flutter app.

Why not? Because it unnecessarily rebuilds the widgets resulting in huge memory usage.

The best solution to manage state, so far, is Provider. However, very recently Riverpod, a modified version of Provider has been gaining popularity, since it does not depend on Flutter anymore and can work independently.

In this book I have explained every bits and pieces of state management in Flutter, so you no longer get confused about state management anymore.

I also help you to understand the mechanism involved inside this confusion. How Flutter uses a separate State object and actually makes stateful Widget immutable or stateless?

This book discusses that topic and more.

The first question that comes to mind is, then what is State in Flutter?

Is that a Widget too? Or a Class? Type? Object?

In this book we've discussed State in a great detail.

If you're an intermediate learner or advanced professional who are still struggling with the complex concept of State in Flutter, then this book is for you!

This book has shown how to manage State efficiently. How to make your Flutter app more performant.

To have more confidence you need to understand the concept of Inherited Widget and how Provider package as a Wrapper class uses that concept too!

And I've discussed that too in great detail.
