when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String id,
    2. String cardId,
    3. String userId,
    4. int quality,
    5. String rating,
    6. double elapsedDays,
    7. int scheduledDays,
    8. double? stability,
    9. double? difficulty,
    10. String? reviewState,
    11. DateTime reviewedAt,
    )
)

A switch-like method, using callbacks.

As opposed to map, this offers destructuring. It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case Subclass2(:final field2):
    return ...;
}

Implementation

@optionalTypeArgs TResult when<TResult extends Object?>(TResult Function( String id,  String cardId,  String userId,  int quality,  String rating,  double elapsedDays,  int scheduledDays,  double? stability,  double? difficulty,  String? reviewState,  DateTime reviewedAt)  $default,) {final _that = this;
switch (_that) {
case _ReviewLog():
return $default(_that.id,_that.cardId,_that.userId,_that.quality,_that.rating,_that.elapsedDays,_that.scheduledDays,_that.stability,_that.difficulty,_that.reviewState,_that.reviewedAt);case _:
  throw StateError('Unexpected subclass');

}
