I have have lots of feature layers which will loaded conditionally hence in my json i have provided visibility as false for all layers then i have modify json conditionally and set visibility to true for some layers.

this method is available in the application itself after the webmap has already loaded. you can get a reference to your featureLayer using something like [responseMap].getLayer("id") Commented Dec 18, 2014 at 17:29
