How can I change the dropdown icon to white? I believe the issue has been solved but I don't know how to activate this function.

useDarkTheme doesn't exist, I believe you mean withDarkTheme

However I have "withDarkTheme = {true}" in my code and it still doesn't work. My current version of the library is "react-native-phone-number-input": "^2.1.0".

I had proposed a pull request, but that is still open and hasn't been merged yet, There are just like 3 little changes, that you can manually add to your local library file.
