AWS Amplify is announcing the general availability of the Authenticator UI library for Flutter. Using the Authenticator UI library, Flutter developers can create a login/registration experience in minutes. When a developer adds the Authentication category and sets the authorization and verification attributes from the Amplify CLI or Amplify Studio, the Authenticator login/registration forms are displayed accordingly. Developers can also apply custom theming to the Authenticator forms, and override validations on login/signup fields. Developers can also add/remove the profile attribute fields used in the sign up form.
