useState troubles to update when receiving new events

Hello everyone, please help with an issue I encountered while using pusher-websocket-react-native. I'm trying to implement a small chat, and the problem is that when I receive a notification in the onEvent method and try to update my local state, the messages value always equals an empty array.

cosnt [messages, setMessages] = useState([])
useEffect(() => {
      getInitialMessagesByRestApi().then(res => {setMessages(res.data)})
}, [])

...
const onEvent = () => {
const onEvent = event => {
    const parsedData = JSON.parse(event.data)

   setMessages([...messages, event.data]) <-- messages in this place always empty
}

I already tried to get initial messages after pusher init, it works but when i am gettig few events like one by one it , messages array always equal to initial without prev message from pusher events

Start with the onEvent callback and the useState/useEffect example in the issue, then determine whether the behavior belongs to the SDK or the consuming React Native code. A useful outcome would be a minimal reproduction or a confirmed explanation of which component is responsible.
