Split the package into two

[Ascenio]

Hello. I've noticed the package does two things: it has widgets integrated with the once and also does the timer logic thing. This mean the package has a unnecessary dependency on Flutter, those running Dart only can't use it. So, it would be nice to split into once and once_flutter, something like that.

It was there flutter_once. But the package once depends on SharedPreferences and it depends on Flutter so the separation would not be useful unless the depending on SharedPreferences changed.

Oh, it does make sense. I thought the lib only managed scheduled jobs while running, I didn't know about the persistence. Maybe there should be a way the user can specify to not use any, so that it can be portable.

We consider it and we will start working on make it available for Dart only project, Thank you!
