ArnaBackButton class
An Arna-styled back button.
An ArnaBackButton is an ArnaButton.icon with a back icon. When pressed, the back button calls Navigator.maybePop to return to the previous route unless a custom onPressed callback is provided.
When deciding to display an ArnaBackButton, consider using
ModalRoute.of(context)?.canPop to check whether the current route can be
popped. If that value is false (e.g., because the current route is the
initial route), the ArnaBackButton will not have any effect when pressed,
which could frustrate the user.
