Safari: 'null' is not a valid value for binaryType; binaryType remains unchanged.

Description

'null' is not a valid value for binaryType; binaryType remains unchanged.

This causes frequent reconnects and messages aren't coming through the messages stream. Seems to only happen in Safari from what I can tell so far.

Steps To Reproduce

description: A new Flutter project.
publish_to: 'none'
version: 0.1.0

environment:
  sdk: '>=3.1.5 <4.0.0'

import 'dart:async';

import 'package:flutter/material.dart';
import 'package:web_socket_client/web_socket_client.dart' as ws;

void main() {
  runApp(const MainApp());
}

class MainApp extends StatefulWidget {
  const MainApp({super.key});

  @override
  State<MainApp> createState() => _MainAppState();
}

class _MainAppState extends State<MainApp> {
  ws.WebSocket? _socket;
  StreamSubscription? _socketMessageSub;
  StreamSubscription? _socketConnectionSub;

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

  @override
  void dispose() {
    _socketConnectionSub?.cancel();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      home: Scaffold(
        body: Center(
          child: Text('Hello World!'),
        ),
      ),
    );
  }

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

    _socket = ws.WebSocket(
      Uri.parse(
        'wss://socketsbay.com/wss/v2/1/demo/',
      ),
    );
    _listenToSocketConnection();
  }

  void _listenToSocketConnection() {
    print('_listenToSocketConnection()');

    _socketConnectionSub = _socket?.connection.listen(
      _onSocketConnectionChanged,
    );
  }

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

    await _socketMessageSub?.cancel();

    _socketMessageSub = _socket?.messages.listen(
      _onSocketMessageReceived,
    );
  }

  void _onSocketConnectionChanged(ws.ConnectionState cs) {
    print('_onSocketConnectionChanged() - $cs');

    if (cs is ws.Connected || cs is ws.Reconnected) {
      _listenToSocketMessages();
    }
  }

  void _onSocketMessageReceived(dynamic data) {
    print('_onSocketMessageReceived() - $data');
  }
}
