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.

The built-in widgets and those available via plugins will allow you to create a great-looking app, but Flutter allows you to manipulate these widgets with layout transformations, such as opacity, rotations, and decorations, allowing you to further improve the user experience (UX) of your app. In this chapter, you will learn how to add these transformations to widgets.

Taking this widget manipulation a step further, Flutter has great support for animations that can be combined and extended to bring the user interface (UI) to life. You will learn about animations, including the use of Tween animations to manage an animation timeline and curve and using AnimatedBuilder to add and combine beautiful animations.

Finally, we will look at some widgets that have animation built directly into them, allowing you to skip the added complication of animation setup and management. They don't fit every situation, but when just a touch...
