I have this implemented in AMD. I use a config file with the basemaps that I want included, and I call createBasemapGallery() at the end of my map load event.
function createBasemapGallery() {
/// <summary>manually create basemaps to add to basemap gallery</summary>
try {
var basemaps = [];
require(["esri/dijit/BasemapGallery", "esri/dijit/BasemapLayer", "esri/dijit/Basemap"], function (
BasemapGallery, BasemapLayer, Basemap
) {
for (b in mybasemaps) {
//load from config array of basemaps
if (mybasemaps.addtomap == true) {
var bm = null
bm = new esri.dijit.BasemapLayer({ url: mybasemaps.url });
var layerBasemap = new esri.dijit.Basemap({
layers: [bm],
id: mybasemaps.svcid,
title: mybasemaps.title,
thumbnailUrl: mybasemaps.thumbnailUrl
});
basemaps.push(layerBasemap)
};
};
//add the basemap gallery, in this case we'll display maps from ArcGIS.com
var basemapGallery = new BasemapGallery({
basemaps: basemaps,
showArcGISBasemaps: false /*config.external*/,
map: map
}, "basemapGallery");
basemapGallery.startup();
// if (config.external) {
// basemapGallery.select('ESRITerrain');
// }
basemapGallery.on("error", handleProcessError);
});
} catch (err) {
errorHandler(err, "createBasemapGallery")
};
};
//config array of mybasemaps
