dependencies:
  diana: ^0.15.1
  diana_grpc: ^0.15.1
  grpc: ^5.0.0
  protobuf: ^6.0.0

Generate Dart code from your .proto, then extend the generated service base. It is a regular singleton injectable — constructor injection, @Value and lifecycle hooks all apply — and the generated DianaApp serves it on its own port next to your HTTP controllers:

import 'package:diana/diana.dart';
import 'package:grpc/grpc.dart' show ServiceCall;

import '../src/generated/greeter.pbgrpc.dart';

@GrpcService()
class GreeterService extends GreeterServiceBase {
  final String greetingPrefix;

  GreeterService(
      @Value('app.greeting', defaultValue: 'Hello') this.greetingPrefix);

  @override
  Future<HelloReply> sayHello(ServiceCall call, HelloRequest request) async =>
      HelloReply()..message = '$greetingPrefix, ${request.name}!';
}

A complete app serving gRPC and HTTP side by side is in examples/greeter_grpc. See the gRPC guide.
