@TheAlphamerc Could you please provide the version information for both the server and the client?

[TheAlphamerc]

Flutter

socket_io_client: ^2.0.3+1

Node

@jumperchen It seems like the server is sending invalid JSON data. So I think the issue is not related to the socket client package itself.

Hi. even i am facing the same issue in flutter windows

socket_io_client: ^2.0.1
