On response, the message is at the bottom of the response not at the top
Issue Description
On response, the message is at the bottom of the response not at the top
Steps to Reproduce / Code Snippets
`const ChatComponent = () => {
const [messages, setMessages] = useState([]);
const onSend = useCallback((newMessages = []) => {
setMessages(previousMessages =>
GiftedChat.append(previousMessages, newMessages),
);
setTimeout(() => {
const loremMessage = {
_id: Math.random().toString(),
text: 'Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industrys standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham..',

export default ChatComponent;`
Expected Results
Actual result (as shown in the screenshot, the message response is displayed at the bottom, so the user needs to scroll up each time to see the beginning of the message.)
Any suggestions here?
Additional Information
- Nodejs version: v19.5.0
- React Native version: 0.72.0
- react-native-gifted-chat version: 2.6.1
- Platform(s) (iOS, Android, or both?): IOS
do you know the workaround for this? has similar expected result on our ends as well

Im not sure if this is the right approach but I did something like this by using the onLayout property of view and passing a function into it.
const chatContainerRef = useRef(null);
`const scrollDownBy300px = () => {
if (chatContainerRef?.current) {
chatContainerRef?.current?.scrollToOffset({
offset: 320, // Scroll down by 300 pixels
animated: true,
});
}
}
const handleLayout = (event: any) => {
const {height} = event?.nativeEvent?.layout; // Get the height of the message
if (currentMessage?.user?._id === 2) {
if (height > 700) {
scrollDownBy300px(); // Call the scroll function if height exceeds threshold
}
}
};
<View onLayout={handleLayout}>
......
</View>
and in gifted chat component passing the below
<GiftedChat
....
listViewProps={{
ref: chatContainerRef,
scrollEnabled: true, // Ensure scrolling is enabled
keyboardDismissMode: 'on-drag', // Dismiss the keyboard when scrolling
automaticallyAdjustContentInsets: false,
}}
/>
`
i see that was nice workaround, unfortunately it might not works for rn 0.68.2 & gifted chat version 1.1.1 (our current setup), but will try this approaches later
