add dart grpc

[ghost]

Would you be open to adding dart grpc ?

Its now quite mature, and also gettign grpc-web soon. I typically use it to do grpc between golang servers and dart clients in flutter.

REPO: https://github.com/grpc/grpc-dart

Tutorial: https://grpc.io/docs/tutorials/basic/dart.html

Here is the tutorial using a Makefile for golang and dart talking over grpc.

# Get golang server and dart client talking over grpc.

# dart Walkthrough : https://grpc.io/docs/tutorials/basic/dart.html
# go equivalent: https://github.com/grpc/grpc-go/tree/master/examples/route_guide

DART_LIBPATH=github.com/grpc/grpc-dart
DART_LIBGOPATH=$(GOPATH)/src/$(DART_LIBPATH)

GO_LIBPATH=google.golang.org/grpc
GO_LIBGOPATH=$(GOPATH)/src/$(GO_LIBPATH)

print:
    @echo 
    @echo DART_LIBPATH $(DART_LIBPATH)
    @echo DART_LIBGOPATH $(DART_LIBGOPATH)
    @echo 
    @echo GO_LIBPATH $(GO_LIBPATH)
    @echo GO_LIBGOPATH $(GO_LIBGOPATH)

dep-os:
    #go get golang.org/x/mobile/cmd/gomobile
    #gomobile init # it might take a few minutes

    # get the dart protoc plugin
    pub global activate protoc_plugin

dep:
    go get -u $(GO_LIBPATH)
    go get -u $(DART_LIBPATH)

dep-clean:
    rm -rf $(DART_LIBGOPATH)
    rm -rf $(GO_LIBGOPATH)

## Golang stuff

go-open-code:
    code $(GO_LIBGOPATH)/examples/route_guide

go-build:
    #cd $(GO_LIBGOPATH)/examples/route_guide && protoc -I protos/ routeguide/route_guide.proto --go_out=grpc:routeguide/generated

    cd $(GO_LIBGOPATH)/examples/route_guide/server && go generate

go-run-server:
    cd $(GO_LIBGOPATH)/examples/route_guide/server && go run server.go -json_db_file $(GO_LIBGOPATH)/examples/route_guide/testdata/route_guide_db.json -port 8080 -tls=true

go-run-client:
    cd $(GO_LIBGOPATH)/examples/route_guide/client && go run client.go -server_addr 127.0.0.1:8080 -tls=true

## Flutter stuff

dart-open-code:
    code $(DART_LIBGOPATH)

dart-build:
    cd $(DART_LIBGOPATH)/example/route_guide && pub get

    # gen dart server
    cd $(DART_LIBGOPATH)/example/route_guide && protoc -I protos/ protos/route_guide.proto --dart_out=grpc:lib/src/generated

    # gen golang server
    #cd $(DART_LIBGOPATH)/example/route_guide && protoc -I protos/ protos/route_guide.proto --go_out=grpc:go/generated

dart-run-server:
    # run server
    cd $(DART_LIBGOPATH)/example/route_guide && dart bin/server.dart

dart-run-client:
    # run server
    cd $(DART_LIBGOPATH)/example/route_guide && dart bin/client.dart -tls=true

ft-build-ios:
    # do this to bootstrap IOS befroe you start coding.
    cd caddy/example && flutter build ios --no-codesign

ft-open-ios:
    # open xcode proj.
    open caddy/example/ios/Runner.xcworkspace

ft-run-ios:
    cd caddy/example && flutter run

Would be nice to have full dart lang too. On Dart client and Dart server (VM) sides.
