Flex/ActionScript - rotate Sprite around its center

var fooShape:Sprite = new FooSpriteSubclass();

fooCanvas.rawChildren.addChild

If you want to rotate around the center, merely center the asset inside your sprite by setting the internal assets x and y to half of the width and height of the asset. This swill center your content and allow it to rotate around a center point.

An example of runtime loaded assets is as follows:

var loader:Loader = new Loader():
var request:URLRequest = new URLRequest(path/to/asset.ext);
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, _onLoaderComplete);
loader.load(request);

private function _onLoaderComplete(e:Event):void
{
    var mc:MovieClip = e.target.content as MovieClip;
    mc.x = -mc.width * 0.5;
    mc.y = -mc.height * 0.5;
    mc.rotation = 90;
    addChild(mc);
}
