Together with SendPort, the only means of communication between isolates.

ReceivePorts have a sendPort getter which returns a SendPort. Any message that is sent through this SendPort is delivered to the ReceivePort it has been created from. There, the message is dispatched to the ReceivePort's listener.

A ReceivePort is a non-broadcast stream. This means that it buffers incoming messages until a listener is registered. Only one listener can receive messages. See Stream.asBroadcastStream for transforming the port to a broadcast stream.

A ReceivePort may have many SendPorts.
