List all scheduled messages

Create a ScheduledMessageListQuery instance to retrieve all scheduled messages matching the specifications set by ScheduledMessageListQueryParams. After a list of all scheduled messages is successfully retrieved, you can access the data of each scheduled message from the result list through the messageList parameter of the callback handler.

Dart

final param = ScheduledMessageListParams();
final query = await ScheduledMessageListQuery(params: param).loadNext();
    // You can handle actions relevant to the scheduled message list of the channel.
}

ScheduledMessageListQueryParams

Property name	Type	Description
order	ScheduledMessageListOrder	Determines the order of the retrieved messages. Acceptable values are `created_at` and `scheduled_at`. (Default: `created_at`)
messageType	MessageTypeFilter	Specifies the message type to filter the messages with the corresponding type. Acceptable values are `all`, `user`, `file`, and `admin`. (Default: `all`)
reverse	bool	Determines whether to sort the retrieved messages in reverse order. If `false`, the results are in ascending order. (Default: `false`)
channelUrl	String	Specifies a target channel to query the scheduled messages from. If `null`, it retrieves scheduled messages from all channels. (Default: `null`)
status	List	Specifies list of scheduled message `status` where scheduled messages with only given `status` are retrieved. (Default: `null`)
