It looks like it's not compatible with flutter 2.0

`Launching lib\main.dart on BKL AL20 in debug mode...

Try to either
- provide an implementation,
- inherit an implementation from a superclass or mixin,
- mark the class as abstract, or
- provide a 'noSuchMethod' implementation.

Start with lib/src/http_client_request.dart, where StethoHttpClientRequest is reported as missing HttpClientRequest.abort. Check how the wrapper handles the other request methods, then verify that the package builds with Flutter 2.0 without the missing-implementation error.
