RecaptchaVerifier constructor

RecaptchaVerifier(dynamic container, [ Map<String, dynamic>? parameters, App? app ])

Creates a new RecaptchaVerifier from container, parameters and app.

The container has different meaning depending on whether the reCAPTCHA is hidden or visible. For a visible reCAPTCHA it must be empty. If a string is used, it has to correspond to an element ID. The corresponding element must also must be in the DOM at the time of initialization.

The parameters are optional Map of Recaptcha parameters. See: developers.google.com/recaptcha/docs/display#render_param. All parameters are accepted except for the sitekey. Firebase Auth backend provisions a reCAPTCHA for each project and will configure this upon rendering. For an invisible reCAPTCHA, a size key must have the value 'invisible'.

The app is the corresponding Firebase app. If none is provided, the default Firebase App instance is used.

verifier = new fb.RecaptchaVerifier('register', {
  'size': 'invisible',
  'callback': (resp) {
    print('Successful reCAPTCHA response');
  },
  'expired-callback': () {
    print('Response expired');
  }
});

Implementation

factory RecaptchaVerifier(container,
        [Map<String, dynamic>? parameters, App? app]) =>
    (parameters != null)
        ? ((app != null)
            ? RecaptchaVerifier.fromJsObject(
                RecaptchaVerifierJsImpl(
                    container, jsify(parameters), app.jsObject),
              )
            : RecaptchaVerifier.fromJsObject(
                RecaptchaVerifierJsImpl(container, jsify(parameters))))
        : RecaptchaVerifier.fromJsObject(RecaptchaVerifierJsImpl(container));
