I want to edit a message, but it's only updated when i changed this message _id. Can someone provide me how to do it, here is my code:
const onSend = useCallback((messagesToSend = []) => {
if(editMessage != null){
setEditMessage()
const m = messagesToSend[0]
const newMessages = [...messages]
const index = newMessages.findIndex(mes => mes._id === editMessage._id);
console.log('index: ', index)
if(index > -1){
newMessages[index].text = m.text // => ***i only edit the text***
// newMessages[index]._id = uuid.v4() => ***this working if changed _id***
console.log('newMessages', newMessages[index]) // => ***new message changed it's text but the bubble not change when re-render***
LayoutAnimation.configureNext(LayoutAnimation.Presets.easeInEaseOut)
setMessage(newMessages)
}
}else{
setReplyMessage()
appendMessage(messagesToSend)
}
})

It looks like you're using useCallback
without a dependency array. This means that any dependencies that you rely on will be memoized and won't update when you run the function.
You should add messages
, editMessage
, and maybe setMessage
and appendMessage
, to the dependency array. Like so:
const onSend = useCallback(
(messageToSend = []) => etc,
[messages, editMessage, setMessage, appendMessage]);
That's the first thing I would try
