RawReceivePort constructor

  1. [Function? handler,
  2. String debugName = '']

Opens a long-lived port for receiving messages.

A RawReceivePort is low level and does not work with Zones. It cannot be paused. The data-handler must be set before the first message is received, otherwise the message is lost.

If handler is provided, it's set as the RawReceivePort.handler.

The optional debugName parameter can be set to associate a name with this port that can be displayed in tooling.


external factory RawReceivePort([Function? handler, String debugName = '']);
