Added a ScrollListener listener to Scrollable. The ScrollListener runs each time the Scrollable's scrollOffset changes. This can be used to keep overlay widgets in sync with a Scrollable below them. Removed the Scrollable ScrollClient API. It was no longer used and was clumsy to use as a ScrollListener. Added global function findScrollableAncestor() to scrollable.dart. Added examples/widgets/overlay_geometry.dart. The app's Scaffold is contained by a Stack. The Stack is used to display green overlay "Markers" at the corners of the most recently selected list item and where the corresponding tap occurred. The app uses widget.localToGlobal() to compute the global overlay positions of the markers. The ScrollListener is used to keep the markers' positions up to date.
Sky Examples
This directory contains several examples of using Sky. Each of these is an
individual Dart application package. If you wish to run them with sky_tool
then you will want to run pub get inside their directory before running
./packages/sky/sky_tool start.

Hello, world. The hello world app is a basic app that shows the text "hello, world."

Stocks. The stocks app is an example of a typical mobile app built using Sky. The app shows a list of all the stocks in the NASDAQ.

Widgets. The widgets app contains a number of Sky widgets so you can experiment with them in a simple container.
