PageStorage in Flutter - how does it work?


I've seen PageStorage in the documentation. From what I understand its almost like a sharedpreference alternative from the Android world.
How do I use it, and why does it need a Widget in it's implementation?
I'm not sure what PageStorage the class is for, but based on your notes, it sounds like you're looking for key value storage.
There is a bug on file about providing a nice plugin for such:
https://github.com/flutter/flutter/issues/4757
PageStorage is for tracking the state of widgets that may not always be instantiated, for example the position of parallel list views in a pageable view (like when when you have several tabs each with its own list). For something like sharedpreference, you should probably use sharedpreference itself (via a plugin). See also https://github.com/flutter/flutter/issues/4757 or https://github.com/flutter/flutter/issues/3427.
