Is there a way to check the connection status?

[steeling]

For e.g. in Go, you first dial out the call, and pass that to the gRPC service client. If the dial fails you know immediately that you were unable to connect.

In dart, I create a grpc client, and even with no internet connection i get no errors. Is there a way to call client.checkConnection() or something would be nice to have
