Flutter implementing socket.io with dart

Question

i am trying to implement socket.io with my flutter app, currently flutter is supporting WebSocket but i have found a way for socket.io in package "dart.io" but i am unable to understand how to emit a message on a specific event. Any suggestions would be helpful :)

Thanks for this GünterZöchbauer :) i think you are right, will test it soon. — Muhammad Faizan

i have tested this plugin but it is unable to connect, My native android side is working find. createSocketIO() has 4 parameters, i have input the domain, have no namespace so i tried empty string and null also but no success in sending the message. Logcat shows the isConnected:false. Need help on this one. — Muhammad Faizan

I think you can read in the documetation about websockets first, flutter socket.io and flutter socket.io client too — rizentium

I have ported socket.io in dart code since 2017, and it can work with flutter as well in the same codebase - socket.io-client-dart and socket.io-dart.

Using this flutter_socket_io package, I managed to connect to my local Socket IO server.

SocketIO socket = SocketIOManager().createSocketIO("http://localhost:3000", "/");
socket.init();
socket.connect();

Maybe you could share your implementation on both client and server side to debug further.

check my last comment to Günter Zöchbauer. "i have tested this plugin but it is unable to connect, My native android side is working fine. createSocketIO() has 4 parameters, i have input the domain, have no namespace so i tried empty string and null but no success in sending the message. Logcat shows the isConnected:false. Need help on this one"

use "/" in namespace parameter as default namespace in socket io

Muhammad Faizan Over a year ago

namespace as you said but still the socket status is interchanging from "reconnecting" to "disconnect" socketIO = SocketIOManager().createSocketIO(SOCKET_URL, "/", socketStatusCallback: _socketStatus); socketIO.init(); socketIO.connect();

i am pretty sure thats not the issue, internet permission is also in the android manifest.
