Delivery receipt is a feature that allows a user to know whether their messages have been successfully delivered to other users in the channel. Once the recipients in the channel receive a message notification or see the message in the channel list view, it will be marked as delivered. The delivery receipt appears in the MessageListComponent of
ChannelModule and in the ChannelListComponent of the
ChannelListModule. If the sender’s message has been delivered to all recipients of the channel, a double-tick icon will appear above the message’s timestamp. Delivery receipt is only visible to the sender of the message.
Note : In order to use this feature, you must first create a channel and enable the chat service. To learn how to allow users to chat in a channel, refer to the Chat in a group channel page.
While the delivery receipt feature is turned on by default in
ChannelModule, you have to set the feature's setter method to
ChannelListModule. Implement the code below to turn on the delivery receipt in a channel list view.
You can customize the UI for delivery receipt through the
icon_done_all property of the icon resource.
