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.

Summary

In this chapter, we got to know how to change our widgets' look by using the Transform class and its available transformations, such as scaling, translating, and rotating. We also saw how we can compound transformations by using the Matrix4 class directly.

We learned the fundamental concepts of animation and how to apply them to child widgets to make changes smooth and dynamic.

We saw the important AnimationController, CurvedAnimation, and Tween framework classes. We also revisited our Transformation examples and added animations to them by using the concepts learned in this chapter. Finally, we saw how to create our own custom Tween objects, and we looked at how to clean up our code through the use of the AnimatedBuilder widget.

Lastly, we saw the AnimatedFoo classes that have animation embedded inside them, allowing you to develop slick animations without complicated code.

In the next chapter, we will look at the app as a whole, complete program and at how...
