SyncedScrollControllers class
Creates pairs of scroll controllers which can be provided to scrollables and ensure that offset change in one scrollable scroll the second one (and vice a versa) There's a bug (or feature) on iOS with bouncing scroll (when it goes out of range) when scrollable get out of sync while in this bouncing position

Properties
- builder → Widget Function(BuildContext context, ScrollController sc11, ScrollController sc12, ScrollController sc21, ScrollController sc22)
-
Positions of 2 pairs of scroll controllers (sc11|sc12 and sc21|sc22)
will be synchronized, attached scrollables will copy the positions
