Supported platforms

  • The app may get disconnected right after the first note is sent on the web at some particular Flutter versions.
  • gRPC-Web is used for web instead of grpc-dart.
  • Sending notes is not supported due to the limited functionality of gRPC-Web.
  • Receiving notes does not start unless you send a request by tapping any one of keys after connected to a server.
  • Tapping more keys cause an error printed in a browser console.
  • A gateway proxy is necessary between a server and clients.
    • See the README of piano_server for details.
