I want to show the sidebar content in a different background color.For that I've tried TouchableOpacity underlay.But that is not the one I'm looking for.After giving TouchableOpacity ,it will change the color of the text only not the entire list background.How do I change the listitem background color as I'm using native base ui kit.Please help.Is there any method to do that?This is how the sidebar looks like.I've done something likes the following.Setting pressStatus as true within onPresList and if it is true change backround color.But navigation to route is not working.There is a mistake

export default SideBar;In the App example from native Base they don't support styles for background items list. So you should change your List component from NativeBase and add a FlatList Component from react native. But you should also return the ListItem component from NativeBase and don't forget the import { FlatList } from "react-native";
You should also modify the onPressList function (I would transform it into an arrow function)
In your states you need to add the state selectedItem: 0
Everytime you press an item, your function would be called by modifying a selectedItem idex, which tells the Flatlist, which Item should get which background. I think this has to be the solution.
If it doesn't compile, make sure that you support arrow functions and that any curly braces or something like that isn't missing.
