Usage

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

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,

  const config = {
    ...
    customizations: [
      'theme',
      'logo'
    ],
  };

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

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.

    <style name="AuthTheme" parent="FirebaseUI">
        <!-- <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>
    </style>

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,

  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.

  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.

  const config = {
    ...
    autoUpgradeAnonymousUsers: true,
  };
