let view;
require([

Accessor,Extent,SimpleLineSymbol,SceneLayer,Draw,geometryEngine,PolygonDrawAction,Sublayer,ImageryLayer,MapImageLayer,
UniqueValueRenderer,Viewpoint,Legend,Print,Directions) {


var map = new Map({
basemap: "topo"
});


view = new MapView({
container: "viewDiv",
map: map,
center: [85.0985,20.5]
zoom: 8
});

var scaleBar = new ScaleBar({
view: view,
unit: "dual"
});
view.ui.add(scaleBar, {
position: "bottom-left"
});


view.when(function() {

var featureLayer = map.layers.getItemAt(0);
var legend = new Legend({
view: view,
layerInfos: [
{
layer: featureLayer,
title: "test"
}
]
});
view.ui.add(legend, "bottom-right");
});


var roadsLayer = new FeatureLayer("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX", {
id : "roadLayerId",
outFields: ["*"],
popupTemplate: {
title: "NAME1 : {XXXXXXXX}:NAME: {XXXK}",
content: "TESTED"
}
});

$("#chkRoadLayer").click(function () {
if(!roadsLayer){
}else {
}
if ($(this).is(":checked")) {
map.add(roadsLayer,1);

} else {
map.layers.remove(roadsLayer);
}
});


//XXXXXXXXXXXXXXXXXXXXXXXXXXXX
//XXXXXXXXXXXXXXXXXXXXXXXXXXXX
//XXXXXXXXXXXXXXXXXXXXXXXXXXXX
//XXXXXXXXXXXXXXXXXXXXXXXXXXXX
//XXXXXXXXXXXXXXXXXXXXXXXXXXXX
//#other codes goes here

});

There is an issue with your require array.

require([
"esri/Map",
"esri/views/MapView",
"esri/WebMap",
"esri/widgets/ScaleBar",
"esri/widgets/BasemapToggle",
"esri/widgets/BasemapGallery",
"esri/layers/FeatureLayer",
"esri/PopupTemplate",
"esri/widgets/Zoom",
function(Map, MapView,WebMap,ScaleBar,BasemapToggle,BasemapGallery,FeatureLayer,InfoTemplate,PopupTemplate,Zoom,Query

Notice: InfoTemplate in your function parameters then PopupTemplate but you do not have a InfoTemplate module in the array so your function parameters are out of sync. Just remove "InfoTemplate" from your function parameters and you will be good.

Thanks Robert 

And below is the code to see the legend on click on checkbox and it is working but Is this correct procedure or not ?

And another thing the same error for Print widget "Export There seems to have been an error."  also coming . please suggest

$("#chkRoadLayer").click(function () {
   if ($(this).is(":checked")) {
               map.add(roadsLayer);
               view.when(function() {
                     legend = new Legend({
                     view: view,
                     layerInfos: [{
                           layer: roadsLayer,
                           title: "LEGEND"
                     }]
                  });
            view.ui.add(legend, "bottom-right");
         });

} else {
      map.layers.remove(roadsLayer);
      legend.destroy();
   }
   });

// For print widget I using the code as below

var print = new Print({
      view: view
});
view.ui.add(print, {
      position: "bottom-left"
});

You are waiting for the view to be ready before you do the print code right? I.e view.when(function() {

It would be best for you to provide your full html page for review.

I actually want to show the legend info after clicking the legend button but I could not set the layer info of legend object after creating the object globally , Then I just tested using  view.when(function() {})

I am sending you the code
