Dart Echo Client Example

This is the Dart version of the canonical Echo Client sample code for Mojo. It starts up the dart_echo_server service and calls the EchoString() interface in that server. The expected result is that it prints hello world.

The source code to the Dart version of the Echo Server can be found in [mojo/src/benchmarks/mojo_rtt_benchmark/lib/echo_server.dart] (https://github.com/domokit/mojo/blob/master/benchmarks/mojo_rtt_benchmark/lib/echo_server.dart).

The tutorial for this code can be found at: https://docs.google.com/document/d/1mufrtxTk8w9qa3jcnlgqsYkWlyhwEpc7aWNaSOks7ug/edit?usp=sharing

Running the code

Run using the Dart echo server, named dart_echo_server.mojo (this name is hardcoded into the client sources as the default server):

$ out/Debug/mojo_shell mojo:dart_echo_client

Run using the C++ echo server to show that any server can implement an interface. Note that .mojo is left off:

$ out/Debug/mojo_shell "--args-for=mojo:dart_echo_client echo_server" mojo:dart_echo_client
