Package app provides app implementations for working with Fyne graphical interfaces. The fastest way to get started is to call app.New() which will normally load a new desktop application. If the “ci” tag is passed to go (go run -tags ci myapp.go) it will run an in-memory application.
func New() fyne.App
New returns a new application instance with the default driver and no unique ID
func NewWithID(id string) fyne.App
NewWithID returns a new app instance using the test (headless) driver. The ID string should be globally unique to this app.
