Guid

Represents a 128-bit globally unique identifier (GUID). A Guid is used across the API when a unique identifier is needed, for example when representing a feature attribute of field type com.arcgismaps.data.FieldType.Guid. Its canonical textual representation follows the Leach–Salz variant, for example {E4904A51-1337-4105-AED6-E1A8EA225DC3}.

The factory method createOrNull is the recommended way to create a Guid object from a string.
