Can I add a feature layer to the flex viewer?

Question

I would like to add a feature layer to the flex viewer so that I can see the layer with a highlighted color. It is not a widget, basically just adding a layer, a feature layer. For example, I put this code in the index.mxml, tried inserting the code inside the or outside of it, but it never show up on the map. Should I go to config.xml, but how to add a feature layer in config file? Million thanks!

I added the code, but nothing showed up.

But it works when I added to the function addLayerToMap() at the bottom. Thanks a lot!
Thanks a lot! It seems I can not change layer's background or outline, the only way to change that is when I creating map server?

Mike,

OK, that make more sense. You need to add it in the MapManager.mxml than. Try adding it to the very bottom of the map_loadHandler function.    var myFL:FeatureLayer = new FeatureLayer("http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer/3");
    myFL.definitionExpression = "STATE_NAME='North Carolina'";
    myFL.mode = "snapshot";
    myFL.outFields= [MALES,FEMALES,NAME,MED_AGE,CNTY_FIPS];
    myFL.symbol = countySymbol;
    map.addLayer(myFL);
