channel property
Set to "true" to enable channel-wide notifications (@channel, @all, etc.), "false" to disable. Defaults to "true".
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
bool? channel;
