serverContext property
The URL by which the root of a server is accessed.
This is the URL against which rest endpoints are resolved. For example, "https://sampleserver3.arcgisonline.com/ArcGIS/rest/services/SanFrancisco/311Incidents/FeatureServer/0" would have a server context of "https://sampleserver3.arcgisonline.com/ArcGIS", on which we could add "/rest/info" or "/rest" to fetch the server information.
Implementation
Uri get serverContext => _serverContext.value;
