SseSourceController class final

Implementation of SseSourceControllerBase where the onErrorEvent action can be specified in parameter, allowing configuration of reconnection logic.

If you need to specify a custom object for the stream, use SseParsedSourceController instead.

If you need more precise control prefer implementing SseSourceControllerBase

Methods

add(Map<String, dynamic> event) → void
Sends a data event.
inherited
addError(Object error, [StackTrace? stackTrace]) → void
Sends or enqueues an error event.
inherited
addStream(Stream<Map<String, dynamic>> source, {bool? cancelOnError}) → Future
Receives events from source and puts them into this controller's stream.
inherited
clear() → Future<void>
Cancel the current HTTP event stream subscription and close the client.
inherited
close() → Future
Closes the stream.
inherited
closeClient() → void
Closes the HTTP client.
inherited
closeCurrentEventStream() → Future<void>
