layout property
Free-form layout id. Provider-specific (title, two-column, image-left, custom). Not enumerated to avoid forcing a breaking change every time a provider adds one.
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? layout;
