package:grpc v3.2.0

  level timeout duration, a timeout may occur sooner than specified in
  connectTimeout. On timeout, a SocketException is thrown.
• Require Dart 2.17 or greater.
• Fix issue #51, add support for custom error handling.
• Expose client IP address to server
• Add a channelShutdownHandler argument to ClientChannel and the subclasses.
  This callback can be used to react to channel shutdown or termination.
