React Native Project Initialization

Welcome to a new React Native project, initialized using the @react-native-community/cli.

Getting Started

Note: Ensure you've completed the React Native - Environment Setup up to the "Creating a new application" step before proceeding.

Step 1: Start the Metro Server

Metro is the JavaScript bundler included with React Native. To start it, execute the following command in your project's root directory:

# Using npm
npm start

# Or using Yarn
yarn start

Step 2: Launch your Application

Keep the Metro Bundler running in its terminal. In a new terminal and from your project's root, execute the following command to run your Android or iOS app:

For Android

# Using npm
npm run android

# Or using Yarn
yarn android

For iOS

# Using npm
npm run ios

# Or using Yarn
yarn ios

If set up correctly, your app should appear in the Android Emulator or iOS Simulator, provided your emulator/simulator settings are accurate. Alternatively, you can also launch your app directly from Android Studio or Xcode.

Step 3: Modify your App

Now that your app is up and running:

Open App.tsx in your preferred text editor and make some edits.
To see changes:
- For Android: Double press the R key or select "Reload" from the Developer Menu (Ctrl + M on Windows/Linux or Cmd ⌘ + M on macOS).
- For iOS: Press Cmd ⌘ + R in the iOS Simulator.

Congratulations! 🎉

You've successfully launched and edited your React Native app. 🥳
