-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`.
-
-1. *Hello, world.* The [hello world app](hello_world) is a basic app that shows
-   the text "hello, world."
-
-2. *Stocks.* The [stocks app](stocks) is an example of a typical mobile app
-   built using Sky. The app shows a list of all the stocks in the NASDAQ.
-
-3. *Widgets.* The [widgets app](widgets) contains a number of Sky widgets so
-   you can experiment with them in a simple container.

-
-Follow these steps to make sure everything works, comparing the
-results to earlier builds:
-
-1. Load the app
-2. Scroll down and up.
-3. Fling down.
-4. Fling up. Verify that it bounces at the top.
-5. Tap on rows. Make sure they get ink splashes.
-6. Open the drawer.
-7. Slide the drawer in and out.
-8. Check that you can change the radio buttons.
-9. Check for ink splashes on each row but not in the header.
-10. Check that you can't scroll the list with the drawer out.
-11. Close the drawer.
-12. Open the menu.
-13. Check the checkbox.
-14. Open the menu. Verify the checkbox is checked.
-15. Tap another menu item.
-16. Hit search.
-17. Type a query like "XXI".
-18. Dismiss the keyboard.
-19. Scroll the list. Verify that you can't overscroll.
-20. Tap the search bar. Verify the keyboard comes back.
-21. Switch to the voice keyboard. Verify that that keyboard works.
-22. Hit the back button.
-23. Verify that the floating action button gets ink splashes.
