Message handler doesn't receive messages

[jhoogstraat]

Since 2.0.0-beta.3-nullsafety.0 my message handler don't receive message anymore.
The logger is showing all messages fine, but the callbacks are not firing.

I got the same issue

@jhoogstraat @Curvel are you trying to transfer binary data. For me problem is when I try to transfer binary data. 2.0.0-beta.1 handles binary data without any issue.

@sha-N Exactly, I try to receive a byte stream.

my workaround was to base64encode at server side and decode at client side
in nodejs server
data: data.toString('base64'),

in dart client
final List<int> _data = base64Decode(data);

@sha-N @jhoogstraat Does any full example to demonstrate this issue? Because I cannot reproduce it on my local env. with 2.0.0-beta.3-nullsafety.0

@jumperchen first of all great work on the library.

To reproduce the issue, try to send any Buffer data from nodejs socketio server to dart client. like gzip data from server.

zlib = require('zlib');
zlib.gzip(data, (err, zipped) => { 
    io.to('client-id').emit('event-name', {id: 'some-id', data: zipped});
});

Sending buffer data from dart client to nodejs server works perfectly.

Fixed by running pub upgrade for socket_io_common
