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:

# 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:

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 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! 🎉

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

Firebase Configuration

To integrate Firebase into your React Native project, follow these steps to add the necessary configuration files for Android and iOS.

1. Add google-services.json for Android

1. Download the google-services.json file from your Firebase project console.
2. Place the google-services.json file in the following directory of your React Native project:

android/app/

3. Ensure the google-services.json file is correctly placed; otherwise, the app will not connect to Firebase services.

2. Add GoogleService-Info.plist for iOS

1. Download the GoogleService-Info.plist file from your Firebase project console.
2. Open your project in Xcode.
3. Drag and drop the GoogleService-Info.plist file into the ios directory of your React Native project (specifically into the root of your Xcode project structure).
4. When prompted, ensure that "Copy items if needed" is checked and click "Finish."
5. Verify that the GoogleService-Info.plist file is included in the "Build Phases > Copy Bundle Resources" section in your Xcode project.

3. Additional Steps

For Android

• Ensure the google-services plugin is applied in your android/build.gradle file:

dependencies {
    classpath 'com.google.gms:google-services:4.4.2'
}

In your android/app/build.gradle file, add:

apply plugin: 'com.google.gms.google-services'

For iOS

Install the required CocoaPods dependencies by running:

cd ios
pod install

After completing these steps, your Firebase configuration files will be successfully integrated into your React Native project.
