end property
End is the EXCLUSIVE upper bound of the window, "2006-01-02" — the day after the last one counted. A board through today reports tomorrow's date here.
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? end;
