Recall a message

Delete a message

Delete a sent message for everyone by calling BaseChannel.deleteMessageForAll(). Only successfully sent messages can be deleted.

By default, Nexconn does not restrict who can recall messages. To add restrictions, consider these options:

• Implement client-side restrictions. For example, prevent regular users from recalling others' messages while allowing admins to recall any message.
• Submit a ticket to enable Chat SDK only allows recalling your own messages on the server side.

Method

Dart

static Future<int> deleteMessageForAll(Message message, OprationHandler<Message> handler)

Parameters

Parameter	Type	Description
message	Message	The message to delete.
handler	OprationHandler<Message>	Callback receiving (message, error). The current Flutter wrapper reports status through error and passes null for message.

Code example

Dart

await BaseChannel.deleteMessageForAll(
  message,
  (_, error) {
    if (error == null) {
      print('Message recalled successfully');
    }
  },
);

Listen for message deletion events

Monitor when a received message is deleted by the sender.

Dart

NCEngine.addMessageHandler('recall-handler', MessageHandler(
  onMessageDeleted: (event) {
    print('Recalled messages: ${event.messages?.length}');
  },
));
