This is a new React Native project, bootstrapped using @react-native-community/cli.

Getting Started

> Note: Make sure you have completed the React Native - Environment Setup instructions till "Creating a new application" step, before proceeding.

Step 1: Start the Metro Server

First, you will need to start Metro, the JavaScript _bundler_ that ships _with_ React Native.

To start Metro, run the following command from the _root_ of your React Native project:

``bash


using npm

npm start

OR using Yarn

yarn start
`

Step 2: Start your Application

Let Metro Bundler run in its _own_ terminal. Open a _new_ terminal from the _root_ of your React Native project. Run the following command to start your _Android_ or _iOS_ app:

$3

`bash


using npm

npm run android

OR using Yarn

yarn android
`

$3

`bash


using npm

npm run ios

OR using Yarn

yarn ios
`

If everything is set up _correctly_, you should see your new app running in your _Android Emulator_ or _iOS Simulator_ shortly provided you have set up your emulator/simulator correctly.

This is one way to run your app — you can also run it directly from within Android Studio and Xcode respectively.

Step 3: Modifying your App

Now that you have successfully run the app, let's modify it.

1. Open App.tsx in your text editor of choice and edit some lines.
2. For Android: Press the R key twice or select "Reload" from the Developer Menu (Ctrl + M (on Window and Linux) or Cmd ⌘ + M (on macOS)) to see your changes!

For iOS: Hit Cmd ⌘ + R in your iOS Simulator to reload the app and see your changes!

Congratulations! :tada:

You've successfully run and modified your React Native App. :partying_face:
