maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(String merchantName, String description, String url, String logoIcon,)?, { 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 merchantName,  String description,  String url,  String logoIcon)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _Metadata() when $default != null:
return $default(_that.merchantName,_that.description,_that.url,_that.logoIcon);case _:
  return orElse();

}
}
