I am trying to use a custom font in a freshly new React-native project made with the typescript template and I do not succeed to add a custom font family.

All the doc I found told me to use rnpm which has been now deprecated in favor of a react-native.config.js file in the root folder.
I therefore created this file in my project but I did not see anywhere where to tell the react-native builder to read it and therefore I get the error font_name not found

Has anyone any suggestion ?

Steps To Reproduce

1. react-native init your_project --template typescript
2. Create a folder assets/fonts and put all your custom fonts : (mine were Lato-(Regular,..).ttf)
3. Create a react-native.config.js in the root folder of your project as follow

module.exports = {
  project: {
    ios: {},
    android: {}, // grouped into "project"
  },
  assets: ['./assets/fonts'], // stays the same
  // commands: require('./path-to-commands.js'), // formerly "plugin", returns an array of commands
};

4. Use the font in the app Component as styling of you text
5. run react-native run-ios
6. You'll get an error "font Lato (in my case) not found"
