The method 'HttpHeadersWrapper.set' has fewer named arguments than those of overridden method 'HttpHeaders.set'. [Dart 2.8]

[jumperchen]

Using rikulo_commons-4.0.1 on Dart 2.8 will cause the following error.

/AppData/Roaming/Pub/Cache/hosted/pub.dartlang.org/rikulo_commons-4.0.1/lib/src/io/http_wrapper.dart:382:8: Error: The method 'HttpHeadersWrapper.set' has fewer named arguments than those of overridden method 'HttpHeaders.set'.
void set(String name, Object value) {

Because of the http.dart, the HttpHeaders.add and the HttpHeaders.set, have three parameters in Dart 2.8 version as follows.

void set(String name, Object value,
{@SInCE("2.8") bool preserveHeaderCase = false});

The issue refers to rikulo/socket.io-client-dart#69
