code property
Code is the minted referral code. Empty on a first apply — applying does not mint a code, approval does; a re-apply echoes whatever the row already holds.
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? code;
