expireTime property
ExpireTime is when the key stops being honored (empty = never). State is the lifecycle flag ("Active", "test", …); "test" mints test-env credentials instead of live ones.
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? expireTime;
