Hello.

I'm implementing chatting with FlatList.

Every time there is a new chat message detected, I do the following.

let newItem = {...}; // read a new chat message from server
let nextFlatListData = this.state.flatListData.slice(0); // clone the chat list
nextFlatListData.push(newItem); // add the new chat to the list
this.setState({flatListData: nextFlatListData}); // update FlatList

It seems that it re-renders every row.

I just need the row for newItem is rendered and the others are NOT re-rendered.

Thank you very much.
