I don't know if it's right to put it up here. But actually this issue related withdartlang. So, I just create issue in here.

After upgrade to 1.22 flutter sdk. And flutter run. It return this error.

Launching lib/main.dart on LGM V300L 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.

Hi, this is because of the breaking change 'Support abort() in HttpClientRequest in Dart:IO' #41904.

We decided to improve the HttpClientRequest class in dart:io by adding an abort() method. This is a breaking change for anyone that implemented the class rather than merely extending it. As such, it was subject to our breaking change policy and we announced it for public discussion and after that, we decided to go ahead with the change. You can read more in #41904.

The breaking change means that any implementations of the HttpClientRequest class must also add their own abort() method. In this case, this is package:io_http, a third party package, that needs to add the missing method. You can file an issue about this in their bug tracker at https://github.com/xinthink/dio_custom_http_adapter/. I'm closing this issue as this is an intentional behavior in the Dart SDK per #41904.
