🎮 Run Example Project

To see all components in action you can run the Example project by following these steps:

1. Clone the project
2. Install node modules by running npm i or yarn at the root of project
3. Run npm run watch or yarn watch to compile and watch source files
4. Run npm run start or yarn start to start the RN packager and keep it open
5. Open example.xcworkspace from /example/ios and run the project from XCode

NOTE: I changed the location of iOS and Android directories and even after specifying new locations on react-native.config we can't run the example project via RN cli. See this issue
