flutter runIf the TLS certificate is accepted, you should see this log entry (because of the dummy gRPC server not sending any responses):
[VERBOSE-2:ui_dart_state.cc(209)] Unhandled Exception: gRPC Error (code: 4, codeName: DEADLINE_EXCEEDED, message: Deadline exceeded, details: null, rawResponse: null, trailers: {})
On TLS failure, you would see something like this:
[VERBOSE-2:ui_dart_state.cc(209)] Unhandled Exception: gRPC Error (code: 14, codeName: UNAVAILABLE, message: Error connecting: HandshakeException: Handshake error in client (OS Error:
CERTIFICATE_VERIFY_FAILED: application verification failure(handshake.cc:359)), details: null, rawResponse: null, trailers: {})
