RN Custom Fonts and RNVectorIcons

// make sure you have not installed react-native vector icons by now

make a file named react-native.config.js, content should be following
```
module.exports = {
    projects: {
      ios: {},
      android: {},
    },
    assets: ['./assets/fonts'],
};
```

As represented in the file, the custom fonts should be made available in the "assets/fonts" folder in the root directory.

ater this, execute the following command
```
yarn react-native link
```
This will 
1. copy the contents into anroid/app/src/main/assets
2. createa a folder called Resources, if not existing in ios and copy these files there.


After this, 
install "react native vector icons and follow the manual procedure of adding the fonts to xcode and android"
