maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(String domain, String aud, String version, String nonce, String iat, String? nbf, String? exp, String? statement, String? requestId, List<String>? resources,)?, { required TResult orElse(), })

A variant of when that fallback to an orElse callback.

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return orElse();
}

Implementation

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult Function( String domain,  String aud,  String version,  String nonce,  String iat,  String? nbf,  String? exp,  String? statement,  String? requestId,  List<String>? resources)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _CacaoRequestPayload() when $default != null:
return $default(_that.domain,_that.aud,_that.version,_that.nonce,_that.iat,_that.nbf,_that.exp,_that.statement,_that.requestId,_that.resources);case _:
  return orElse();

}
