Overview of this book

There have been many attempts at creating frameworks that are truly cross-platform, but most struggle to create a native-like experience at high performance levels. Flutter achieves this with an elegant design and a wealth of third-party plugins, making it the future of mobile app development. If you are a mobile developer who wants to create rich and expressive native apps with the latest Google Flutter framework, this book is for you. This book will guide you through developing your first app from scratch all the way to production release. Starting with the setup of your development environment, you'll learn about your app's UI design and responding to user input via Flutter widgets, manage app navigation and screen transitions, and create widget animations. You'll then explore the rich set of third party-plugins, including Firebase and Google Maps, and get to grips with testing and debugging. Finally, you'll get up to speed with releasing your app to mobile stores and the web. By the end of this Flutter book, you'll have gained the confidence to create, edit, test, and release a full Flutter app on your own.

There are still areas of the Dart language that we haven't yet explored, and these will be introduced as we progress through the book. However, you now have sufficient knowledge of Dart to get up and running and build your first Flutter application—exciting, isn&apos...
