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.

Summary

In this chapter, we have looked at the various APIs available within Fyne for managing and storing data. We explored the concept of data binding and saw how it can help keep a user interface up to date, while at the same time reduce the amount of code we need to write.

We then looked at the Preferences API, which allows us to persist user data between application launches. When combined with the data binding code, this came with no additional complexity. By utilizing these features, we implemented an example application that manages data for tracking water consumption and stored it on our local device, ready to use the next day.

With that, we have covered the most common standard widgets and functionality in the Fyne toolkit. Sometimes, an application may require widgets or features that are not included. To support this, the toolkit allows us to extend the built-in components. We will explore this in the next chapter.
