위와같은 에러가 발생하면서 안되는 것 확인했고 검색하여

stackoverflow 답변을 통해 해결했습니다

 

 

해결 :

 

1. 문제 발생한 dart 소스 파일을 vi로 엽니다.

(저의 경우 ~/.pub-cache/hosted/pub.dartlang.org/dwds-12.1.1/lib/src/services/chrome_proxy_service.dart)

 

2. 에러 발생한 라인 (540라인) 이동

(vi로 열었을 시 명령어는 :540입력 후 엔터

 

3. (1번 컬럼은 line number)

 540   Future<SourceReport> getSourceReport(String isolateId, List<String> reports,
 541       {String scriptId,
 542       int tokenPos,
 543       int endTokenPos,
 544       bool forceCompile,
 545       bool reportLines}) async {

 

이렇게 돼있을텐데

 

 540   Future<SourceReport> getSourceReport(String isolateId, List<String> reports,
 541       {String scriptId,
 542       int tokenPos,
 543       int endTokenPos,
 544       bool forceCompile,
 545       bool reportLines,
 546       List<String> libraryFilters}) async {

 

이렇게 수정한다 (굵게 처리된 부분을 추가)

 

그리고 다시

# flutter packages pub global activate webdev

...생략

+ web_socket_channel 2.2.0
+ webdev 2.7.8 (2.7.9 available)
+ webkit_inspection_protocol 1.1.0
+ yaml 3.1.1
Building package executables...
Built webdev:webdev.
Installed executable webdev.
Warning: Pub installs executables into $HOME/.pub-cache/bin, which is not on your path.
You can fix that by adding this to your shell's config file (.bashrc, .bash_profile, etc.):

  export PATH="$PATH":"$HOME/.pub-cache/bin"

Activated webdev 2.7.8.

 

성공했다

 

 

원인 : 대충 ChromeProxyService 소스가 dwds-12.1.1 dart 소스 dwds-12.1.1패키지에 맞지 않게 되어있었음
