How to handling error in grpc stream client?

[bonetoy]

Client code:

final clientCall = rpcClient.streamFunc(rpcStreamController.stream);
await for (var response in clientCall){
   ...
}

---

I saw some grpc error in locat like this:

Unhandled Exception: gRPC Error (code: xx, codeName: Internal, message: Ops, details: [], rawResponse: null, trailers: {})

I can't find a suspicious place for me to throw or handle exceptions. 😂

Does

try {
  final clientCall = rpcClient.streamFunc(rpcStreamController.stream);
  await for (var response in clientCall){
   ...
  }
} catch (e) {
}

not catch it?
