Overview of this book

“Anyone interested in developing Flutter applications for Android or iOS should have a copy of this book on their desk.” – Amazon 5* Review Lauded as the ‘Flutter bible’ for new and experienced mobile app developers, this recipe-based guide will teach you the best practices for robust app development, as well as how to solve cross-platform development issues. From setting up and customizing your development environment to error handling and debugging, The Flutter Cookbook covers the how-tos as well as the principles behind them. As you progress, the recipes in this book will get you up to speed with the main tasks involved in app development, such as user interface and user experience (UI/UX) design, API design, and creating animations. Later chapters will focus on routing, retrieving data from web services, and persisting data locally. A dedicated section also covers Firebase and its machine learning capabilities. The last chapter is specifically designed to help you create apps for the web and desktop (Windows, Mac, and Linux). Throughout the book, you’ll also find recipes that cover the most important features needed to build a cross-platform application, along with insights into running a single codebase on different platforms. By the end of this Flutter book, you’ll be writing and delivering fully functional apps with confidence.

How it works...

Navigator is a component of both MaterialApp and CupertinoApp. Accessing this object is yet another example of the of-context pattern. Internally, Navigators function as a stack. Routes can be pushed onto the stack and popped off the stack.

Normally, you would just use the standard push() and pop() methods to add and remove routes, but as we discussed in this recipe, we didn't just want to push StopWatch onto the screen – we also wanted to pop LoginScreen from the stack at the same time. To accomplish this, we used the pushReplacement method:

Navigator.of(context).pushReplacement(
MaterialPageRoute(

We also used the MaterialPageRoute class to represent our routes. This object will create a platform-aware transition between the two screens. On iOS, it will push onto the screen from right, while on Android, it will pop onto the screen from the bottom.
