If you only followed the section The Basics, there will be no controls. If you continued on to the Controls and Layout sections, then you should be seeing controls.
Maybe you forgot to set a layout, or maybe you forgot an
addChild() call. It's hard to say without seeing your code.
Are you using a theme? If not, that would probably explain it. Feathers for Starling does not have default skins, so you either need to use a theme or provide your own skins.
