As a result, the APIs need to define everything involved in building a graphical application. In this section, we will explore the main concepts in running a Fyne-based application and producing visible components on screen, starting with the application itself.

Application

The application, defined in the fyne.App interface, models the capabilities of a Fyne-based application. Each app using Fyne will typically create and run a single fyne.App instance from within their main() function. Because of the way that graphical applications work, they must be started from the main function and not through a goroutine or other background thread.

To create an app instance, we make use of the app package within Fyne, which can be imported using fyne.io/fyne/v2/app. This...
