You can also write synchronous code as the parameters are shared between the async and sync methods but we don't provide usage examples of such.

Get message updates

You can receive updates when specific messages and related message reactions are added, edited, or removed on other clients using the following methods:

• streamUpdates() checks message and message reaction-related updates on a single Message object.
• streamUpdatesOn() checks message and message reaction-related updates on a list of Message objects.

Both methods return an asynchronous stream which produces a new value whenever someone adds, edits or deletes a message, or adds or removes a message reaction to/from the specific message(s).

Underneath, these methods subscribe the current user to a channel and add a message reactions event listener to receive all messageAction events of type added or removed.

Stream update behavior

• streamUpdates() returns the entire updated Message object (including all message reactions) each time a change occurs.
• streamUpdatesOn() returns the complete list of messages you're monitoring each time any change occurs to any of them.

Method signature

These methods take the following parameters:

• streamUpdates()

  1message.streamUpdates() -> AsyncStream<MessageImpl> 

• streamUpdatesOn() (static)

  1MessageImpl.streamUpdatesOn(
  2    messages: [MessageImpl],
  3) -> AsyncStream<[MessageImpl]>

Input

Parameter	Required in streamUpdates()	Required in streamUpdatesOn()	Description
messages Type: [MessageImpl] Default: n/a	No	Yes	A collection of MessageImpl objects for which you want to get updates on changed messages or message reactions.

Output

An asynchronous stream that produces updates when the underlying message(s) change.
