Authgear SDK for Flutter

With Authgear SDK for Flutter, you can easily integrate authentication features into your Flutter apps. In most cases, it involves just a few lines of code to enable multiple authentication methods, such as social logins, passwordless, biometrics logins, one-time-password (OTP) with SMS/WhatsApp, and multi-factor authentication (MFA).
