maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(List<String> chains, String domain, String nonce, String uri, CacaoHeader? type, String? nbf, String? exp, String? statement, String? requestId, List<String>? resources, int? expiry, List<String>? methods,)?, { 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( List<String> chains,  String domain,  String nonce,  String uri,  CacaoHeader? type,  String? nbf,  String? exp,  String? statement,  String? requestId,  List<String>? resources,  int? expiry,  List<String>? methods)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _SessionAuthRequestParams() when $default != null:
return $default(_that.chains,_that.domain,_that.nonce,_that.uri,_that.type,_that.nbf,_that.exp,_that.statement,_that.requestId,_that.resources,_that.expiry,_that.methods);case _:
  return orElse();

}
