Powering your Flutter apps with gRPC
summary
Claims that Flutter + Dart can power full‑stack apps using gRPC with auto‑generated Dart stubs from proto3 files, yielding protobuf messages that are about 8x faster than JSON. Demo shows a stock app using gRPC server‑side streaming over HTTP/2 (client connects to localhost:8080 or a Cloud Run URL), generated code via protoc, containerized with Docker and deployed to Cloud Run; Postman is used for testing and Envoy is suggested for browser workarounds.
