GrpcError.unknown constructor
Unknown error. An example of where this error may be returned is if a Status value received from another address space belongs to an error-space that is not known in this address space. Also errors raised by APIs that do not return enough error information may be converted to this error.
Implementation
const GrpcError.unknown([this.message, this.details, this.rawResponse])
: trailers = const {},
code = StatusCode.unknown;
