Flutter Auth Buttons

Flutter widget library containing buttons for authenticating with popular social networks.

These buttons do not contain authentication logic. They are designed to be used with authentication packages, such as firebase_auth. Use the onPressed attribute to capture the button press and call your authentication logic within that.

GoogleSignInButton(onPressed: () {
  // call authentication logic
