when<TResult extends Object?> method

@optionalTypeArgs TResult when<TResult extends Object?>(TResult $default(String? issuer, String? authorizationEndpoint, String? tokenEndpoint, String? deviceAuthorizationEndpoint, String? userinfoEndpoint, String? mfaChallengeEndpoint, String? jwksUri, String? registrationEndpoint, String? revocationEndpoint, List<String>? scopesSupported, List<String>? responseTypesSupported, List<String>? codeChallengeMethodsSupported, List<String>? responseModesSupported, List<String>? subjectTypesSupported, List<String>? idTokenSigningAlgValuesSupported, List<String>? tokenEndpointAuthMethodsSupported, List<String>? claimsSupported, bool? requestUriParameterSupported, bool? requestParameterSupported, List<String>? tokenEndpointAuthSigningAlgValuesSupported,))

A switch-like method, using callbacks.

As opposed to map, this offers destructuring. It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case Subclass2(:final field2):
    return ...;
}
