maybeMap<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeMap<TResult extends Object?>({
  1. TResult success(
    1. WriteSuccess<T> value
    )?,
  2. TResult failure(
    1. WriteFailure<T> value
    )?,
  3. 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( WriteSuccess<T> value)?  success,TResult Function( WriteFailure<T> value)?  failure,required TResult orElse(),}){
final _that = this;
switch (_that) {
case WriteSuccess() when success != null:
return success(_that);case WriteFailure() when failure != null:
return failure(_that);case _:
  return orElse();

}
}
