When you say "smooth" do you mean you want to animate the scrollbars?
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
               xmlns:s="library://ns.adobe.com/flex/spark">
    <fx:Declarations>
        <s:Animate id="myAnimate" target="{scroller.viewport}">
            <s:SimpleMotionPath property="verticalScrollPosition" valueBy="100" />
            <s:SimpleMotionPath property="horizontalScrollPosition" valueBy="100" />
        </s:Animate>
    </fx:Declarations>
    <s:controlBarContent>
        <s:Button label="scroll" click="myAnimate.play()" />
    </s:controlBarContent>
    <s:Scroller id="scroller" width="300" height="300">
        <s:Group>
            <s:Button label="large button" width="1200" height="1200" />    
        </s:Group>
    </s:Scroller>
</s:Application>
