Failed to generate the grpc code for Dart --dart_out: protoc-gen-dart: Plugin failed with status code 252.

[heyphat]

I follow the instruction to download and install protoc and protoc plugin for dart here.
I use Linux
protoc version 3.6.0

I could not generate the code for dart and this error message came out:
--dart_out: protoc-gen-dart: Plugin failed with status code 252.
and
Crash when compiling file:///home/phat/.pub-cache/global_packages/protoc_plugin/bin/protoc_plugin.dart.snapshot, at character offset null: String starting with ' must end with '. #0 ErrorToken.lexeme (package:front_end/src/fasta/scanner/error_token.dart:74:24) #1 _withArgumentsExpectedDeclaration (file:///tmp/tmpcU3f4j/dart-2.0.0-dev.64.1/dart/pkg/front_end/lib/src/fasta/fasta_codes_generated.dart:1989:25) #2 Parser.reportRecoverableErrorWithToken (package:front_end/src/fasta/parser/parser.dart:6020:20)

Thank you!

@tanphathuynh did you manage to solve this as I am having the same issue

@lvh1g15 I am still having this problem on my computer. But I tried to generate on another new machine, it works. Still not sure what the problem is.

Try re-install/upgrade protoc_plugin everytime Dart is updated on your system. That solves it for me.

@mohammed90 thanks for the help

Any link/info on simple way to reinstall the plugin?

pub global activate protoc_plugin
