Answer 1

I ran into the same issue and found ChromeProxyService's implementation (dwds-12.1.1) doesn't match vm_service-8.3.0.

You can take a dirty fix as follows.

1. Open chrome_proxy_service.dart in your pub directory (~/.pub-cache/hosted/pub.dartlang.org/vm_service-8.3.0)
2. At line 540, add the missing argument: List<String> libraryFilters

  @override
  Future<SourceReport> getSourceReport(String isolateId, List<String> reports,
      {String scriptId,
      int tokenPos,
      int endTokenPos,
      bool forceCompile,
      bool reportLines,
      List<String> libraryFilters}) async {
