prevChannelId property
The channel ID of the previous channel, used when switching channels. Providing this ID will cause push notifications to clear on the channel being switched to.
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? prevChannelId;
