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, solidifying its status as 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. You’ll start with the basics of cross-platform development frameworks, specifically Flutter. You’ll then explore the Dart programming language which is the foundation of the Flutter framework. Next, you’ll get a feel for Flutter and how to create your first app, followed by an exploration of the various popular plugins that supplement the Flutter framework. Finally, you’ll explore testing and app release, including some common glitches that you may experience. By the end of this book, you’ll be well-equipped to create and release a basic Flutter app along with gaining a solid understanding of the Flutter framework and Dart language.

As we have seen, MaterialPageRoute and CupertinoPageRoute are classes that add a route to the navigator. You may have noticed as we experimented with the example app that they add a transition between the old and new Route. These transitions align with the platform defaults but can be customized as well.

On Android, for example, the entrance transition for the page slides the page upward and fades it in. The exit transition does the same in reverse. On iOS, the page slides in from the right and exits in reverse.

Flutter lets us customize this behavior by letting us add transitions between screens. To do this, we need to look a little deeper at routes.

PageRouteBuilder

PageRouteBuilder is a helper class that can be used for custom Route creation, instead of using the pre-built...
