maybeMap<TResult extends Object?> method

@optionalTypeArgs TResult maybeMap<TResult extends Object?>(TResult $default(_RequiredNamespace value)?, { required TResult orElse(), })

A variant of map that fallback to returning orElse.

It is equivalent to doing:

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

Implementation

@optionalTypeArgs TResult maybeMap<TResult extends Object?>(TResult Function( _RequiredNamespace value)?  $default,{required TResult orElse(),}){
final _that = this;
switch (_that) {
case _RequiredNamespace() when $default != null:
return $default(_that);case _:
  return orElse();

}
}
