This section shows the way to configure all Sign In features: SMS, Google, Facebook, Email, Apple; show/ hide Login options, add Forgot Password. Most of these features require Firebase to be set.

You can do these steps to configure the new App when using any service for Firebase:

  1. Using the Firebase Console, add an Android app to your project: Follow the assistant, download the generated google-services.json file, and place it inside android/app.
  2. Using the Firebase Console, add an iOS app to your project: Follow the assistant, download the generated GoogleService-Info.plist file, open ios/Runner.xcworkspace with Xcode, and within Xcode place the file inside ios/Runner.

When installing, if you get issue, please go to Common Questions or Common Issues to find the solutions.
