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, 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.

With Spring Boot being the leading framework for building applications in the JVM ecosystem and AWS the leading cloud platform, their combination is quite powerful. This book will teach you everything you need to know to get your Spring Boot application running on AWS. Throughout this book, we'll develop a web application that seamlessly integrates common AWS services such as SQS, S3, SNS, RDS, Cognito, and ECS using Spring Cloud AWS. Not only will we focus on developing the application with Spring Boot but also take a detailed look at getting it ready for production. This includes a continuous deployment pipeline, infrastructure-as-code using CloudFormation and AWS CDK, deployment patterns, and monitoring.

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