Connection Error: WebSocketException: Connection to 'https://example.com:0/socket.io/?EIO=4&transport=websocket#' was not upgraded to websocket

[Jimesh843]

This is my code for socket connection:

socket = IO.io(
'https://example.com/',
<String, dynamic>{
'autoConnect' : false,
'transports' : ['websocket'],
'extraHeaders': {'foo': 'bar'},
},
);

I have used socket_io_client: ^2.0.3+1 and from backend i have used 4.7.3 version of node and i have also set code necessary for server. but still can't connect.

Is there any permission required on server side or from my side

hey , you would have to add a path too , seems like your socket object is missing it
