It seems you are trying to reach a Socket.IO server in v2.x with a v3.x client, but they are not compatible

I'm Android flutter. How do I fix this? I still have problems with 3.x references

pub.dev doesn't have a 3.x version

@codesdevs If you use the socket.io client version 1.0.2, that should work
