Each ArcGIS Experience Builder widget has a manifest.json file, which describes a widget's attributes and properties. A widget manifest needs to include the name, type,
version, exbVersion, and translatedLocales properties. The easiest way to create a widget manifest, is to copy the manifest.json file from the demo widget. The following is an example of a manifest.json file.
