Building Cross-Platform GUI Applications with Fyne

Overview of this book

The history of graphical application development is long and complicated, with various development challenges that persist to this day. The mix of technologies involved and the need to use different programming languages led to a very steep learning curve for developers looking to build applications across multiple platforms. In Building Cross-Platform GUI Applications with Fyne, you'll understand how the Go language, when paired with a modern graphical toolkit such as Fyne, can overcome these issues and make application development much easier. To provide an easy-to-use framework for cross-platform app development, the Fyne project offers many graphical concepts and design principles that are outlined throughout this book. By working through five example projects, you'll learn how to build apps effectively, focusing on each of the main areas, including the canvas, layouts, file handling, widgets, data binding, and themes. The book will also show you how the completed applications can then be run on your desktop computer, laptop, and smartphone. After completing these projects, you will discover how to prepare applications for release and distribute them to platform marketplaces and app stores. By the end of this book, you'll be able to create cross-platform graphical applications with visually appealing user interfaces and concise code.

Building your application for release

As we saw in Chapter 9, Bundling Resources and Preparing for Release, the fyne package command bundles our application binary and metadata into a format that can be installed on operating systems (OSes) just like any native graphical application. However, in addition to differing formats for each platform, there are additional considerations when looking to distribute software, such as certification and app store upload file formats. To handle this, there is another sub-command within the build tool, fyne release.

In this section, we will learn how to use the release command to prepare an application for sharing.

Running the release command

Just like the fyne package command that we saw in Chapter 9, Bundling Resources and Preparing for Release, this new release command is responsible for packaging up our application with its metadata. The release command, however, applies changes to the application in preparation for distribution. The...
