Feature Description
To block a user's messages, add the user to the blocklist.
Blocklist
Blocking a user
By default, a blocked user does not know that he/she is "blocked". After the user sends a message, the error code indicating that he/she has been blocked will not be returned.
To have the "You have been blocked by the user" error message returned after a blocked user sends a message, you can log in to the IM console, select Feature Configuration > Login and Message > Blocklist Check, and disable Show "Sent successfully" After Sending Messages. Then the SDK will report error code 20007 after a blocked user sends a message.
// Add a user to the blocklistV2TimValueCallback<List<V2TimFriendOperationResult>> addBlackList = await friendshipManager.addToBlackList(userIDList: ['user1']);
Unblocking a user
Call

Getting the blocklist
