Feature Description
The method for recalling a message is in the core class TencentImSDKPlugin.v2TIMManager.getMessageManager().
The receiver listens for a message recall notification through addAdvancedMsgListener.
Recalling a Message
The sender can recall a successfully sent message.
By default, the sender can recall a message sent within two minutes. You can change the time limit for message recall as instructed in Feature Configuration. Message recall can be implemented through the receiver UI code: When a message is recalled, the receiver will receive the onRecvMessageRevoked notification which contains the msgID of the recalled message. You can identify the recalled message at the UI layer based on the msgID and change the bubble for the message to the "Message recalled" status.
Recalling a message (by the sender)
The sender calls revokeMessage (Details) to recall a message. Sample code:
V2TimCallback revokeMessage = await TencentImSDKPlugin.v2TIMManager.getMessageManager().revokeMessage(msgID: "");
Noticing a message recall (by the receiver)
1. Call addAdvancedMsgListener (Details) to set the advanced message listener. 2. Receive a message recall notification through onRecvMessageRevoked (Details). Sample code:
onRecvMessageRevoked: (String messageid) {
// Process the recalled message among locally maintained messages
},
