handle property
Handle is the display name shown on a listed row: 1-40 characters of letters, digits, space, dot, underscore, apostrophe or hyphen. Left empty on a listing opt-in it defaults to the caller's username.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
String? handle;
