Hi everyone, I'm new at javascript and developping widgets for WAB for developpers. js widget I am currently trying to develop an off-panel widget, which aim would be geolocating the user and  creating a point in a layer I previously published on ArcGIS Server as a Feature Service. (Works like a panic button) I am having some trouble at finding out what could be wrong with this.addGraphic (line 65) at the function zoomToLocation. Console says the following: Uncaught TypeError: this.addGraphic is not a function at zoomToLocation (Widget.js?wab_dv=2.15:65) Here is my code: define([    'dojo/_base/declare',    'jimu/BaseWidget',    'esri/graphic',    'esri/geometry/Point',    'esri/symbols/SimpleMarkerSymbol',    'esri/symbols/SimpleLineSymbol',    'esri/Color',    "esri/layers/FeatureLayer"    ],    function(declare, BaseWidget, Graphic, Point, SimpleMarkerSymbol, SimpleLineSymbol, Color, FeatureLayer) {       return declare([BaseWidget], {          baseClass: 'jimu-widget-panico',          name: "Panico",          graphic: null,          currLocation: null,          watchId: null,          postCreate: function() {             this.initFunc();          },          initFunc: function(){             if(navigator.geolocation) {                navigator.geolocation.getCurrentPosition(this.zoomToLocation, this.locationError);             }             else {                alert("error.");             }          },                    locationError: function(error) {             if(navigator.geolocation) {                   navigator.geolocation.clearWatch(this.watchId);                }                switch (error.code) {                   case error.PERMISSION_DENIED:                      alert("Location not provided");                      break;                   case error.POSITION_UNAVAILABLE:                      alert("Current location not available");                      break;                   case error.TIMEOUT:                      alert("Timeout");                      break;                                      default:                      alert("unknown error");                      break;                }       },       zoomToLocation: function(location) {          var pt = new Point(location.coords.longitude, location.coords.latitude);             this.addGraphic(pt);             this.map.centerAndZoom(pt, 12);          var featureLayer = new          FeatureLayer("https://localhost:6443/arcgis/rest/services/..../FeatureServer/0", {             outFields: ["*"]          });          graphic = new Graphic(pt);          featureLayer.applyEdits([graphic], null, null);       },       addGraphic: function(pt){          var symbol = new SimpleMarkerSymbol(                SimpleMarkerSymbol.STYLE_CIRCLE,                12,                new SimpleLineSymbol(                   SimpleLineSymbol.STYLE_SOLID,                   new Color([210, 105, 30, 0.5]),                   8                ),                new Color([210, 105, 30, 0.9])             );             graphic = new Graphic(pt, symbol);             this.map.graphics.add(graphic);       }    }); }); ...
