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...

Mastering this tool is critical to getting into a flow state when developing your UIs. A common criticism of Flutter is that deeply nested widget trees can make code very hard to edit. This is the reason why tools such as the intentions dialog exist.

As your Flutter knowledge grows, you should strive to become more reliant on these tools to improve your efficiency and accuracy. If you want, try running through this recipe again, but this time, don't use the helper tools—just edit the code manually. Notice how hard it is, and how easy it is to mismatch your parentheses, breaking the whole tree? 

For the curious, the intentions dialog feature is powered by a separate program called the Dart Analysis Server. This is a background process that isn't tightly coupled to your IDE. Both Android Studio and VS Code talk to the same server. When you open the intentions dialog, your IDE sends the token you are currently highlighting to the server, which analyzes...
