4. Run your project (`Cmd+R`)



#### Android



1. Open up `android/app/src/main/java/[...]/MainApplication.java`

  - Add `import com.oijusti.firebaseuiauth.RNFirebaseuiAuthPackage;` to the imports at the top of the file

  - Add `new RNFirebaseuiAuthPackage()` to the list returned by the `getPackages()` method

2. Append the following lines to `android/settings.gradle`:

    ```

    include ':react-native-firebaseui-auth'

    project(':react-native-firebaseui-auth').projectDir = new File(rootProject.projectDir,  '../node_modules/react-native-firebaseui-auth/android')

    ```

3. Insert the following lines inside the dependencies block in `android/app/build.gradle`:

    ```

      implementation project(':react-native-firebaseui-auth')

    ```



## Usage



```javascript

import Auth, {AuthEventEmitter, AuthEvents} from 'react-native-firebaseui-auth';



...



  componentDidMount() {

    this.eventListener = AuthEventEmitter.addListener(

      AuthEvents.AUTH_STATE_CHANGED,

      event => {

        console.log('user:', event.user);

      }

    );

  }



  componentWillUnmount() {

    this.eventListener.remove(); //Removes the listener

  };



  Auth.signIn(config)

    .then(user => console.log(user))

    .catch(err => console.log(err));



...



  Auth.getCurrentUser().then(user => console.log(user));

### UI Customization

Optionally, you can use the option `customizations` to change the look of the authentication screens. This does not apply to the actual sign-in buttons and their position. What you can change depends on the platform.












##### Android

The values available for android customization are as follows,

```javascript

  const config = {

    ...

    customizations: [

      'theme',

      'logo'

    ],

  };

```

First add FirebaseUI in your build.gradle (:app),

```javascript

dependencies {

    implementation 'com.firebaseui:firebase-ui-auth:6.4.0'

    ...

```



For `theme`, add the next style in your `styles.xml`, then copy into the `drawable` folder an image to use for background and name it `auth_background.png`.

```javascript

    

        <!-- <item name="colorPrimary">@color/colorPrimary</item> -->

        <!-- <item name="colorPrimaryDark">@color/colorPrimaryDark</item> -->

        <!-- <item name="colorAccent">@color/colorAccent</item> -->



        <item name="colorControlNormal">@android:color/white</item>

        <item name="colorControlActivated">@android:color/white</item>

        <item name="colorControlHighlight">@android:color/white</item>

        <item name="android:windowBackground">@drawable/auth_background</item>

    

```

For `logo`, copy an image in the `drawable` folder and name it `auth_logo.png`.



##### iOS

The values available for iOS customization correspond to specific screens and are as follows,

```javascript

  const config = {

    ...

    customizations: [

      'auth_picker',

      'email_entry',

      'password_sign_in',

      'password_sign_up',

      'password_recovery',

      'password_verification'

    ],

  };

```

Open your project in `XCode` and add the `.xib` file of the screen you want to customize. The .xib files are located in `./ios/custom-screens/` of this library. Let's say, you want to customize the `auth-picker` screen, add the file `FUICustomAuthPickerViewController.xib` and use the XCode tools to add it labels, images, change colors, and so on.



### Email Password Settings

You can control whether new users can sign in or not by using the option `allowNewEmailAccounts`. Also, if you do not want to require the user name during sign up you can set the option `requireDisplayName` to false.

```javascript

  const config = {

    ...

    allowNewEmailAccounts: false,

    requireDisplayName: false,

  };

```



### Anonymous User upgrade Settings

When an anonymous user signs in or signs up with a permanent account, the `autoUpgradeAnonymousUsers` option allows you to link the existing account (anonymous) with permanent account. This way the user can continue with what they were doing before signing up. By default this option is disabled.

```javascript

  const config = {

    ...

    autoUpgradeAnonymousUsers: true,

  };

```



## Example Project

Download example from [react-native-firebaseui-auth-example](https://github.com/oijusti/react-native-firebaseui-auth-example)



Create a project in the [Firebase Console](https://console.firebase.google.com) and add apps for Android and iOS. Then enable Email/Password provider in Authentication.



#### Android

Make sure you type `com.example` in the `Android package name` field.



Download the file `google-services.json` in the android/app folder.



#### iOS

Make sure you type `com.example` in the `iOS bundle ID` field.



Download the file ``GoogleService-Info.plist`` in the ios/example folder and add it into the project using xcode.



Update pods `$ pod install`
