Check out the section called "Add an array of client-side features" in the expand section called "Creating a FeatureLayer" in this help doc.  Also, check out the 'dataUpdating' property of the FeatureLayerView. ... View more

Another option I've done previously, and if you're controlling the entire UX, is to disable the ability of the child layers to change their own visibility if the parent layer is not visible. ... View more

Seems like you have esriRequest and esriConfig incorrectly configured, along with missing references. Try this instead: require(["esri/Map", "esri/views/MapView", "esri/widgets/Search", "esri/identity/IdentityManager", "esri/identity/ServerInfo", "esri/request", "esri/config"], (EsriMap, MapView, Search, IdentityManager, ServerInfo, esriRequest, esriConfig) => {   ...

The error message when calling the method with your coordinates is: message: "input geometry spatial reference is not supported" Here's a slightly updated version that doesn't throw the error message: https://codepen.io/john-grayson/pen/LYoVmXG I hope this helps. ... View more

Can you share a Codepen or similar showing why you can't use the results of this method? ... View more

Using FeatureEffect is a great way to highlight or make your data stand out for your one or more feature(s) using one or more visual effects.  Check out the linked samples in the doc... ... View more

Andrea,     if you rotated the map then the extent might not be what you think it is.  As mentioned by Steve, you should not use the extent as it will not provide the correct intersection results since the geometry and the extent are different.  Maybe something like the code below might help.  Also, its hard to tell exactly what might be going on, so something that will help is if you have a CodePen or similar so we can experience the issue and help you out. const searchGeometry = event.graphic.geometry; const intersections = graphicsLayer.graphics.filter((graphic) => geometryEngine.intersects(searchGeometry,graphic.geometry) );   ...

I just tried with previous versions of the api (back to 4.7) and it seems like it's always been zero based.  It always helps to track down these types of use cases if you share a CodePen (or similar) showing the issue. https://codepen.io/john-grayson/pen/eYozyrY ... View more

As Matt suggested, I too would recommend the use of CIMSymbols and the symbol builder app which is a great way to help us get started. I used the symbol builder to mock up the symbol json for the line layer and then I updated one of the samples to create this CodePen, which I then further tweaked to connect the label text to a feature attribute via the primitive overrides and Arcade.  Hopefully these links will help in your task. ...

You might want to check out CIMSymbol and its ability to override primitives via Arcade expressions as it might provide the necessary functionality. https://developers.arcgis.com/javascript/latest/api-reference/esri-symbols-CIMSymbol.html https://developers.arcgis.com/javascript/latest/api-reference/esri-symbols-CIMSymbol.html#CIMPictureMarker https://developers.arcgis.com/javascript/latest/api-reference/esri-symbols-CIMSymbol.html#PrimitiveOverride ...

If the stretch raster function is not going to be used  conjunction with other raster functions to provide additional context to the processing of the pixels, then you might instead just use a stretch renderer if all you need is visualization. I've updated the CodePen to show this simpler alternative. ... View more

Try the geometryService.labelPoints(...) method to see if it gives you what you need: https://developers.arcgis.com/javascript/latest/api-reference/esri-rest-geometryService.html#labelPoints ... View more
