The flutter default Snackbars are a major PITA to use as they require a
Scaffold, additionaly, they will not be shown if the parent Scaffold is
destroyed, which is the case when deleting a note and returning to the
main screen.
It's time to start using a proper logger so we can control the number of
log messages, also - it helps to have a central configuration point for
the logs, specially since I would like to hook them up to Crashlytics in
the future.
