Android when the message is very long does not scroll correctly

[hareshmabbly]

Describe the bug
Currently when we have long messages in message list then list scroll become laggy and this issue happens only on android in ios everything works fine from our side we tried to made few changes to optimize the performance one of them is changing FlatList to FlashList but no much improvement happen.

Dev environment info (please complete/provide the following information):

• Package version : "stream-chat-expo": "5.12.0",
• expo version : "expo": "^48.0.7",
• Device/Emulator : Android (any android device we tested in z4 fold and samsung S series)
• Offline support enabled No

To Reproduce

1. Create any group chat.
2. Add 50+ messages where most of the messages should be long like more then 1000 words.
3. Try to scroll list and then try to scroll only long message you will see the laggy behaviour.
4. Make sure above all are performed in Android device only because in ios everything seems fine.

Expected behavior

@hareshmabbly not sure if its still relevant, but this was a known issue in react-native for inverted flatlist. Although it has been fixed in RN 0.72.4 so please make an upgrade. facebook/react-native#30034 (comment)
