Device details:

• Device: [iPhoneXR]
• OS: [e.g. iOS9]
• Package Version [0.3.3]
• Flutter (Channel stable, v1.7.8+hotfix.3, on Mac OS X 10.14.5 18F132, locale zh-Hans-CN)

My Code

class SocketUtils {
  static SocketIOManager manager;
  static SocketIO socket;

  static Future socketTo() async {
    manager =new SocketIOManager();
    //配置socket链接信息
    SocketOptions socketOptions = new SocketOptions(
      'https://ci.icxinli.com',
      query: {
        'token': testToken,
        'source': 'CONSULTANT',
      },
      transports: [Transports.WEB_SOCKET, Transports.POLLING],
      enableLogging: true,
    );
    socket = await manager.createInstance(socketOptions);
    socket.onConnect((res) {
//      socket.emit('rooms', []);
      print('onConnect--------' + res);
    });
    socket.on('rooms', (rooms) {
      print('rooms1111========' + rooms.toString());
      print('rooms2222========' + rooms[0].nickName);

      print('rooms3333========' + rooms.toString());

    });
    socket.connect();
  }
}

When I try running the app using the example code from the adhara socket plugin on iOS, nothing happens. It neither connects, emits a message or even throw an error.
Runs as expected on Android and the mobile browser.

Expected behavior
Should display, connected and message received from the socket server.

Device details:

• Device: [e.g. iPhoneXr Emulator]
• OS: [e.g. iOS12]

unable to disconnect either via kManager and manager. any problem?

  SocketIOManager manager = SocketIOManager();
    SocketIO socket = await manager.createInstance(SocketOptions('http://********/', enableLogging: false));

    global.kManager = manager;
    global.kSocket = socket;

.

await kManager.clearInstance(kSocket);

How to disable log of socket echo?

I'm trying to move SocketIO instance to this page:

import 'dart:async';

import 'package:adhara_socket_io/adhara_socket_io.dart';
import 'package:flutter/material.dart';

class MyPage extends StatefulWidget {

  final String groupID;
  final Color groupColor;
  final SocketIO socket;
  static final String routeName = '/my_page';

  MyPage({ @required this.groupID, @required this.socket,  Key key, this.groupColor }) : super(key: key);

  @override
  _MyPageState createState() => new _MyPageState();
}

And I'm calling it like this:

    SocketIO socketObj = await new SocketIOManager().createInstance(
        HttpMGR.getServerURL(), 
        query: {
            'Authorization': ACCESS_TOKEN,
            'groupID': ''**********GROUP_ID********'
        }
    );

    socketObj.connect();

    Navigator.of(context).push(
         MaterialPageRoute(
             builder: (BuildContext context) => new MyPage(
                 groupID: '**********GROUP_ID********', 
                 socket: socketObj
             )
         )
     );

But instead this class throws this exception and the page don't load:

I/flutter ( 6901): The following NoSuchMethodError was thrown building Builder:
I/flutter ( 6901): The getter 'socket' was called on null.
I/flutter ( 6901): Receiver: null

How to disconnect with server?

SocketIOManager().clearInstance(socket);
doesnt work

manager = SocketIOManager();
setState(() => isProbablyConnected = true);
socket =
await manager.createInstance(socketUrl, query: {}, enableLogging: true);
socket.onConnect((data) {
print("connected...$data");
socket.emit("message", ["Hello World"]);
});
socket.onConnectError(pprint);
socket.onConnectTimeout(pprint);
socket.onError(pprint);
socket.onDisconnect(pprint);
socket.on('news', (data) {
print("hi" + data);
});
socket.connect();

I am running flutter app on real device and trying to connect socket on my server IP but it failed to connect.

I/Process (25663): Sending signal. PID: 25663 SIG: 9
Lost connection to device.

Steps to reproduce the error:

1. switch to either channel master or channel beta by:
   flutter channel master
   or
   flutter channel beta

2. run the example adhara_socket_io app in Android device or emulator (I did not check IOS).

Additional Information on why this error happens:

1. Pay attention to this line in the above error log:

E/EventThread(25663): java.lang.RuntimeException: Methods marked with @UiThread must be executed on the main thread. Current thread: EventThread

2. There was a change in flutter commited @2019/05/04, that:

The Android embedder is now checking that platform->Dart messages are sent from the platform thread.

Pls. take a look at here:

Other flutter package (the image_picker) that has the same problem

and here:

Pls go to line 601

Current Work Around

use channel stable by the command:

flutter channel stable

I ran the example on IOS with this URI const String URI = "http://192.168.1.100:7000?auth=12345";. I got socket.request._query on the server to be { b64: '1', transport: 'polling' } but on Android, I got { auth: '12345', EIO: '3', transport: 'polling' } which is the expected data.

Secondly, how do I change transport from polling to websocket?

On my Widget I run the following "initSockets" method to initiate the connection to socket.io:

Flutter code

@override
void initState() {
  super.initState();
  initSockets();
}

@override
void dispose() {
  subscription.cancel();
  socketIOManager.clearInstance(socket);
  super.dispose();
}

void initSockets() async {
  print('initSockets');

  socket = await socketIOManager.createInstance(localServerAddress());
  socket.onConnect((data){
    print("connected...");
  });
  socket.on("top_events", (data){
    print("top_events");
  });
  socket.onDisconnect((data){
    print('disconnected from socket.io');
  });
  socket.onReconnect((data){
    print('reconnected to socket.io');
  });
  socket.connect();
}

If I do a Hot Restart a new connection is created without disposing of the old one. I have to Terminate the app and start it again, and only when the app terminates do the web socket connections get disconnected.

NodeJS server log

(This is one continuous log without restarts. It's separated into chunks to mention what is being done on the Flutter App.)

Does this plugin work with socket.io server using HTTPS?

I have implemented the adhara socket.
i have successfully emitted and received the message from server side but the problem is the socket is again connecting and sending the request indefinitely.
how to stop this?

Latest flutter update seems to have complications with this package

flutter/engine@904cfc4#diff-1fa18ffd4ca48402f3b9437b82337f31

Describe the bug
I tried connecting to my socket.io using the example code and trying to connect to my local socket.io server. But it doesn't connect and when I enable the onConnectError listener I get the following error
onConnectErrorio.socket.engineio.client.EngineIOException: xhr poll error

Expected behavior
The app should be able to connect to the socket after a button click.

Error launching application on iPhone 6s.

I cannot find the adhara_socket_io/adhara_socket_io-Swift.h file anywhere.

Everything is in the title. To install the latest version, I had to put this in my pubspec.yaml file.

adhara_socket_io:
    git:
      url: git://github.com/infitio/flutter_socket_io.git

1. socket was created - working
2. connected to server - working
3. socket.emit("start_session", xxxx...); - does not work

The emit command does not work on iOS, on Android everything works fine..?

Is it possible to send data as Map directly for example socket.emit("msg", {'key': 'value'}); instead of socket.emit("msg", [{'key': 'value'}]); ?
Sorry it's kinda a feature request.

Describe the bug

Unable to receive updates from the socket server on the client. I am able to create a successful connection and emit messages too. However, I am not receiving any updates in the event callback.

Version used : adhara_socket_io: ^0.1.11

To Reproduce

Below is the code used to connect:

socket.on("connect", (response) {
print(response);
socket.emit("join", [{
"channelName": channelName }]);

`socket.on("event_name", (data) {
	print(data);
});`

}); socket.connect();

I receive emitted message on the server successfully using socket.emit.

Expected behavior
Data received in the socket.on callback.

Adhara_socket_io doesn't specify a Swift version and none of the targets integrating it have the 'SWIFT_VERSION' attribute set.

wss://? not support

Client receive it 4 times ( Ordinary emit work fine

Error launching application on HighPeaksw iPhone X.

I am trying to run on ios simulator and during the build process I get the following error:

Unable to determine Swift version for the following pods:
- adhara_socket_io does not specify a Swift version and none of the targets (Runner) integrating it have the SWIFT_VERSION attribute set. Please contact the author or set the SWIFT_VERSION attribute in at least one of the targets that integrate this pod.

Describe the bug
the reqId must be marked as an optional variable, on line 77

Expected behavior
let reqId: String? = arguments["reqId"] as? String

// Client
socket.emit('my event name', ['my first param', (message) {
print(message);
} ] );

// Server [Node]
socket.on('my event name', (data, callback) => {
return callback('Success');
} ] )

When I run the function, I got an error "Invalid argument: Closure: (dynamic) => Null"

Socket not working on iOS because of namespace issue.

https://github.com/infitio/flutter_socket_io/blob/master/ios/Classes/AdharaSocket.swift

Above file doesn't have any code for namespace.
It should be like this.

let manager = SocketManager(socketURL: URL(string:"http://localhost:8080/")!)
let defaultNamespaceSocket = manager.defaultSocket
let swiftSocket = manager.socket(forNamespace: "/swift")

Describe the bug
If the event data received from the server is not formatted as JSON an exception is thrown.

To Reproduce
Steps to reproduce the behavior:

1. Modify the server send message to be:
   socket.emit('news', 'hello world');

Expected behavior
The .on event should support strings or ignore the data.

Device details:

• Package Version 0.1.11

How to listen messages from server?

I use socket.on for do that, is there another way?

Ty

How do one get responses from emitting events? I did

dynamic res = socket.emit("messages", [{"userId": "1223"}]);

But doesn't return anything. Any other way for this?

Xcode's output:
↳
/Users/yonathanmichalsky/Desktop/RemoteWorker-App/ios/Pods/Socket.IO-Client-Swift/Source/SocketIO/Engine/SocketEngine.swift:316:11: error: value of type 'WebSocket' has no member
'onHttpResponseHeaders'
ws?.onHttpResponseHeaders = {[weak self] headers in

Version: 0.1.9

It is not possible to send Characters like : = or .

I am using a backend that has a socket.io server. To connect, I need to send authentication headers. There doesn't seem to be a way to set it.

How can I pass the authorization headers (Authorization: ${Token}).

Version 0.3.3 is not working onSending Data... is not working nothing...
just work in 0.2.0
i will stay 0.2.0

Describe the bug
When I try to use this package with Android SDK 28, I get spammed with "web socket error" in the debug console and the socket can't connect. After multiple hours of work trying to merge my application with the example I found out that it worked by replacing compileSdkVersion and targetSdkVersion from 28 to 27 in android/app/build.gradle.

To Reproduce
Update the example to Android SDK 28

Expected behavior
The socket should connect normally.

When i tried to connect to my domain https://iportao.com I got untrusted chain error... but the SSL is ok because I use socket.io on other projects using this domain.

    SocketIO socket = await manager.createInstance(server, query: {}, enableLogging: true);

    socket.onConnect((data){
      print("connected...");
      print(data);
      socket.emit("sendMessage", ["Hello world!"]);
    });

    socket.on("receiveMessage", (data){   //sample event
      print("receiveMessage");
      print(data);
    });

    socket.onConnectError((error){
      print('connection error');
      print(error);
    });

    socket.connect();

///Disconnect a socket instance and remove from stored sockets list
  Future clearInstance(SocketIO socket) async {
    await _channel.invokeMethod('clearInstance', {'id': socket.id});
    _sockets.remove(socket.id);
  }

case "clearInstance":
                if(arguments["index"] == nil){
                    result(FlutterError(code: "400", message: "Invalid instance identifier provided", details: nil))
                }

the "index" should be "id"

Console returns me this errors:

I/flutter (10845): On error: io.socket.engineio.client.EngineIOException: xhr poll error
I/flutter (10845): Disconected: transport error

Is this problem on Flutter app or in server configuration?
I hosting sockets on AWS.

Thanks for help.
