그래서 이 문장들을 찾았다.

설정(Lantern):

export https_proxy=127.0.0.1:61538또는 설정:
export http_proxy=socks5://127.0.0.1:1080
export https_proxy=$http_proxy결과:
curl https://android.googlesource.com/문제없다
curl https://www.google.com/오류: Server aborted the SSL handshake.그리고
flutter doctor 여전히 오류 (여전히https://android.googlesource.com/접근할 수 없음;그렇지만https://storage.googleapis.com/flutter_infra/flutter/$version/은(는) 액세스할 수 있습니다.로그를 보려면 다음과 같이 하십시오.

} 몇 가지 수정을 했는데 그 안의 논리가 매우 간단하다는 것을 발견했다.
Future updateAll() async {
if (!_lockEnabled)
return null;
for (CachedArtifact artifact in _artifacts) {
if (!artifact.isUpToDate())
// ，
await artifact.update();
}
} artifact.업데이트 안의 논리는 파일이 존재하는지, 버전이 일치하는지 확인하고, 조건이 충족되면 업데이트하지 않아도 되고, 그렇지 않으면 다운로드할 수 없다는 것이다.다운로드의 논리는 임시 디렉터리에 다운로드한 다음bin/cache에 압축을 풀고 xxx를 만드는 것이다.stamp 파일은 버전 번호를 기록합니다.
그리고bin/cache 디렉터리에 있는 flutter 삭제tools.stamp 및 fluttertools.snapshot, 다시 실행

부록:
1.logger의 사용법은 나도 모르지만packages/fluttertools/lib/src/base/logger.dart는 원본 파일이 있기 때문에 사용법을 알 수 있습니다: print Error, print Status, write To StdOut, print Trace, start Progress.
2.File.path 나도 몰라. 그래서 구글, 찾았어.https://www.dartlang.org/dart-vm/dart-by-example,api를 찾아보면 알 수 있습니다.
