The Following example will populated a dynamic component design picklist with all SLDS icons names.

public override VisualEditor.DynamicPickListRows getValues() {

VisualEditor.DynamicPickListRows allPicklistValus = newVisualEditor.DynamicPickListRows();

//Gets All Icons 
Map<String,Object> allIcons = getAllIcons();

for(String category :allIcons.keySet()) {

//Gets All Icons per category
List<String> iconNames = (List<String>)allIcons.get(category);


for(String icon:iconNames){

   VisualEditor.DataRow value =newVisualEditor.DataRow(icon,icon);

   allPicklistValus.addRow(value);

}}

returnallPicklistValus;

}
