Unfortunately, I couldn't find any relevant information on generating a wallpaper with the specified requirements. However, I can suggest some alternatives to achieve a similar look.

You can use a library like react-native-vector-icons and expo/vector-icons to display vector icons, and then combine them with an image (such as a PNG) to create a custom wallpaper.

Here's a simple example using React Native:

import React from 'react';
import { View, Image } from 'react-native';
import Feather from 'react-native-vector-icons/Feather';

const Wallpaper = () => {
  return (
    <View>
      <Image source={require('./FC.png')} style={{ width: '100%', height: '100%' }} />
      <Feather name="rocket" size={50} color="#fff" style={{ position: 'absolute', top: 50, left: 50 }} />
      <Feather name="star" size={30} color="#fff" style={{ position: 'absolute', bottom: 50, right: 50 }} />
    </View>
  );
};

export default Wallpaper;

This code displays a PNG image with two vector icons on top of it. You can customize the appearance and positioning of the icons to fit your needs.

Please note that this is just an example, and you'll need to adjust the code to suit your specific requirements.
