maybeMap<TResult extends Object?> method

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