I have the following code that is currently working. I have been looking all over and cannot find how to change the icon way from the tiny dot that defaults on the location. The code below is set to a specific address on page load.
I have tried PictureMarkerSymbol as you'll see I have that loaded into the function, but I'm not getting the right logic.
I figured this would be the easy part of using arcgis, but it's proving to be difficult.
thanks!

It looks as the search widget resultGraphic is readonly, but it looks like you can specify a collection of SearchSource and provide it a symbol. You can almost use the default setting provided in an example under sources in documentation. Below is an example. You can use this tool for creating symbols.

I am using a map with feature layers from ArcGIS and the popup to see some data when the user click on a symbol (feature). Is there a way to style the popups exactly the way we want ? In other words, how could I get the data out of the popup, not display the popup but open a modal with that data instead ? Is that even possible ?
This are actually two questions, can you style the popup?, and can you use your own "popup"?.
For the first one, I would say it is pretty customizable, but obviously it depends what you need.
For the second, you just need to stop the default behavior of the view popup, that is to open on right click, and then catch the event yourself to do what you want. Here is an example I made for you that shows that,

Currently working on showing a popup in the map using ESRI ArcGIS API for JavaScript 4.15.
But that is missing the Maximize button which was available with ArcGIS API for JavaScript 3.35
Is there any config to be set to show the same.
As far as I know the new API does not have that capability out of the box. But no worries, you can implement it by adding a custom action to the popup.
See the example I made for you to get an idea.

To run the snippet, copy and save as an html file. The full screen action does not work in the snippet, I guess because it is embedded, not sure though.
I have to change the default icon on the Locate widget on arcGIS 4.18. The default icon class is, esri-icon-locate how can I change it to the class, 'esri-icon-navigation'?
I am going through the documentation,
https://developers.arcgis.com/javascript/latest/api-reference/esri-widgets-Locate.html#iconClass
I have tried to use the property, 'iconClass'. But not reflecting in the map icon. Please find the code below,
var locateBtn = new Locate({
view: view,
// iconClass: '\ue666'
iconClass: 'esri-icon-navigation'
});
view.ui.add(locateBtn, {
position: "manual",
});
KER,
You actually right, does not work as expected. Setting iconClass should be the solution.
Funny fact if you check the default iconClass is actually esri-icon-north-navigation, which obviously in not.
Anyway, I am gonna give a dirty solution, just overlap the class you want,
view.when(_ => {
const n = document.getElementsByClassName("esri-icon-locate");
if (n && n.length === 1) {
n[0].classList += " esri-icon-navigation"
}
});

I'm using arcGIS SceneView in local viewing mode to display a WebMap. I'm trying to constrain the zoom level and bounds of an area so that the user can only see the US, Hawaii, and Alaska and cannot pan outside of this. I also need to constrain the zoom level because if the user zooms out too far the over-zoom the map and see untiled/unmapped space.
Are there any potential solves for this? I first thought that using the constraints property might solve it, but it appears the properties that can be fed to this are quite limited:
https://developers.arcgis.com/javascript/latest/api-reference/esri-views-SceneView.html#constraints
One way to achieve what I think you want is:
listen to view property changes,
check constraints,
act accordingly.
Take a look a the example I made for you. In it, I wait for the view to stop updating (updating property), then I check the constraints. If it is out of scale or out of the extent I reset the view. You probably want another action, I just made it simple.

Let's consider this code from the reference (https://developers.arcgis.com/javascript/latest/api-reference/esri-widgets-Popup.html#open):
view.on("click", function(evt){
view.popup.open({
location: evt.mapPoint, // location of the click on the view
title: "Some title",
});
This works. But how to open a popup at the point, specified by predefined lng,lat coords?
First try:
var point = new Point({latitude:lat,longitude:lng});
view.popup.open({
location: point,
title: "Some title"
});
This does not work. The reason is that created point currently disconnected from map view. Is there a way to receive screen coords (x,y) of the current view by specified (lng,lat)? In google maps api there're methods like latLngToDivPixel, latLngToDivPoint, so what argis offers for this task?
Looks like you're having a SpatialReference issue. Since you're creating the point via lat/lng, it's not in WebMercator, so when you add it to the map it's going to the wrong place. Here's a fixed code for you:
// this works, but needs to be in webmercator:
// var point = new Point({x:-9035831.315416021, y:3095345.196351918});
// as an alternative you can translate to webmercator on the fly:
var point = webMercatorUtils.geographicToWebMercator(new Point({latitude:28.526622,longitude:-81.914063}));
view.popup.open({
location: point,
title: "Some title"
});
Here is the above code in an example.
The answer/issue above was correct for version 4.0 and 4.1.
However, for the newly released version 4.2, this has been simplified. Popup.location now automatically converts WGS84 (latitude, longitude) points to web mercator when map is in web mercator projection.
