Hey guys, first of all I'm glad for this package, using it for a month now.

PusherOptions only takes cluster as a parameter but I need to set host and port.

Can you guys help me to achieve that or add it to the package if you have time to do that?

I've also do some work on it but It gives me connection exception, I'd appreciate some help. https://github.com/mirkancal/pusher-websocket-flutter

pusher_websocket_flutter: ^0.1.1

The code shown below is successfully initialized, connected and subscribed to pusher service but doesn't receive data from the channel.bind method. If I put logs in _initializePusherService and subscribe I can see them, but not from inside channel.bind.

Tested and does not work:

1. Real devices with iOS versions: 12.4.3 and 13.1.3 (iPhone 5s and iPhone X)
2. On every iPhone available in Xcode simulator

Note: This code works perfectly on any android version and device. (Receiving data)

Reproducible code

import 'dart:async';
import 'package:pusher_websocket_flutter/pusher.dart';

const channelName = "myChannelName";
const eventName = "myEventName";
const clusterName = "myClusterName";

class PusherService {
  static final PusherService _instance = PusherService._privateConstructor();

  StreamController<List> _streamController = StreamController<List>.broadcast();
  Sink get _inEventData => _streamController.sink;

  factory PusherService() {
    return _instance;
  }

  PusherService._privateConstructor() {
    _initializePusherService();
  }

  void _initializePusherService() async {
    await Pusher.init("pusherUrl", PusherOptions(cluster: clusterName));
    Pusher.connect(
        onConnectionStateChange: (ConnectionStateChange connectionState) async {
      print('PusherService - connection status changed: ' +
          connectionState.currentState);
    }, onError: (ConnectionError error) {
      print('PusherService - error: ' + error.message);
    });
  }

  void subscribe() {
    Pusher.subscribe(channelName).then((Channel channel) {
      channel.bind(eventName, (Event last) {
        print("PusherService - Received new data");
        _inEventData.add(last.data);
      });
    });
  }

  void unsubscribe() {
    print("PusherService - Unsubscribing from this service.");
    Pusher.unsubscribe(channelName);
  }
}

I am importing this class in main.dart fail and calling it like this

  @override
  void initState() {
    PusherService().subscribe();
  }

Here is my flutter doctor -v

Good night to who created this library.

Today I come with a question to you, since I would like to implement push notifications through pusher in my flutter app, I look forward to your response

I am able to receive pusher events when the app is running in background or when the app is open . When i clear the app from background it does not receive events .

When trying to include version 0.0.7 to the project, I get an error first that SWIFT_VERSION is not specified in the Podfile, after which I open podfile and add version 4.1 as a dependency. Then another error appears, related to umbrella header, I have no idea how to fix:

What am I missing here? Podfile has platform set to 9.0, and swift version set to 4.1. I've also tried with 4.0, 5.0, and no luck...

I have a view with a bottomNavigationBar, when I move between each tab, the Pusher connection changes to: DISCONNECTED. I only execute the action of "pusher.connect" in the initState of the view

Hi,

After I run pod install, I get these errors:

[!] A license was specified in podspec pusher_websocket_flutter but the file does not exist - .../ios/.symlinks/plugins/LICENSE

[!] Unable to read the license file ../../LICENSE for the spec pusher_websocket_flutter (0.1.1)

[!] Unable to read the license file ../../LICENSE for the spec pusher_websocket_flutter (0.1.1)

I see the license file but it at .../ios/.symlinks/plugins/pusher_websocket_flutter/LICENSE

Please help!

Thanks, Shilpi

Hello, thank you very much for this package. I am successfully able to subscribe to the public channels and receive events that are sent from the pusher debug console. The exception is thrown when I am trying to subscribe to private channels. I have in the backend written in laravel. I'm not a back end developer so I could not debug if the problem is on the back end.

I pass the required auth endpoint and also the request headers to PusherAuth. When I try to connect to the pusher cancel and subscribe to a private channel I get this file not found exception which points to the auth endpoint URL as below

I cannot add the real URL above in the logs so added . The laravel code does not have any auth endpoint set, so according to the laravel docs the default is /broadcasting/auth. Any help is appreciated.

The following code is supposed to works for the initialization of pusher Works in Android and iOS

 await Pusher.init( "KEY", PusherOptions(cluster: "-",), enableLogging: true);

With flutter web this initialization code is even unable to initiate, no errors apparently, just the line is never completed and the code gets stopped.

I am trying to subscribe to a private room, but getting this invalid signature error.

Invalid signature: Expected HMAC SHA256 hex digest of 8910.66062685:private-5eb108e1110adb4c7da27e34, but got 64ea520ef7a27ed2604d36768c514e2ba38fe78273edfba77878b77585bb90fd

I've read this (https://support.pusher.com/hc/en-us/articles/360019306433-I-receive-Invalid-signature-Expected-HMAC-SHA256-error-what-is-that-) article and tried a few changes in the backend but it is not working.
