To get the most out of this book

A basic knowledge of the Go language is assumed throughout this book. If you are not yet familiar with the syntax or concepts, consider running through the online tutorial before you begin reading (tour.golang.org).

To run the examples, you will need at least version 1.12 of Go installed, as well as a C compiler for your computer (required by the Fyne library code). If either of these are not installed, you can find detailed steps in Appendix A, Developer Tool Installation. We will step through the process of installing the Fyne library and its supporting tools as they are required throughout the book:

To develop applications, you will need a Windows, macOS, or Linux computer with the development tools described previously. To test applications on mobile devices, you will also need the Android SDK and/or Xcode (for iOS/iPadOS) environment installed. For more information, refer to Appendix B, Installation of Mobile Build Tools. For the further testing of mobile builds, it is advisable to have a suitable mobile device available.

To derive additional benefits from this book, it would be ideal if you have in mind an app project you are aiming to build. Doing so will help to practice the example code in different settings to better understand the widget and API capabilities. Additionally, this will mean that the app store upload process at the end of this book will result in a published version of your application!

If you are using the digital version of this book, we advise you to access the code via the GitHub repository (link available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
