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.

When using zsh, you can add a line to your zshrc file, which is a text file that contains the zsh configuration. If the file does not exist yet, you can create a new file, as follows: 

  1. Open the zshrc file with the following command:
nano $HOME/.zshrc

This will open a basic text editor called nano in your terminal window. There are other popular tools, such as vim and emacs, that will also work.

  1. Type the following command at the bottom of the file:
export PATH="$PATH:$HOME/flutter/bin"
  1. If you chose to install Flutter at a different location, then replace $HOME with the appropriate directory.
