webdev 2.7.4
'webdev serve web:9000' as instructed in the readme file of grpc-web doesn't work, because main.dart.js is missing.
'webdev build' fails to produce main.dart.js --> with following complain:
"[WARNING] build_web_compilers:entrypoint on web/main.dart: Skipping compiling grpc_web|web/main.dart with dart2js because some of its transitive libraries have sdk dependencies that are not supported on this platform:"
"grpc|lib/src/shared/status.dart
grpc|lib/src/server/call.dart"
Above 2 files contain imports from **'dart.io'** which causes the failure. When I remove reference to dart.io from above 2 files, build succeeds.
## Repro steps
1. step1: Clone grpc-dart
2. step2 : cd grpcdart/example/grpc-web
3. step3 webdev build or webdev serve web:9000
with: webdev 2.7.4
