Add single marker based on coordinates

Anonymous User — Thu, 04 Aug 2022 12:18:54 GMT

I'm developing a custom widget on Experience Builder, that would basically have additionnal features than the Search Widget, especially since we have a particular geolocator.

It's all working good, until I want to add a marker to the map to mark the location searched by the user.

I tried to use the sample provided by the documentation and have slightly adapted for EB, but I get a Typescript error when I create the Graphic object ("t is undefined"). I don't get the error without these lines.

What am I missing ?

TypeScript doesn't work with autocasting, so you'll have to add a Color and an Outline explicitly

symbol: new SimpleMarkerSymbol({ style: "square", color: new Color([0, 0, 255]), size: "8px", outline: new SimpleLineSymbol({ color: new Color([255, 255, 0]), width: 3 }) })

Thank you for your answer, I missed that indeed.

Unfortunately, I edited my code but I still get the same error.

When creating the Point with x/y, you also need to set the spatialReference. If you know the SR matches the the map, you can use view.SpatialReference.

geometry: new Point({ x: event.value.x, y: event.value.y, spatialReference: view.spatialReference // set sr of Point }),
