maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String id,
    2. String? chunkId,
    3. String topicId,
    4. String questionType,
    5. String questionText,
    6. String? expectedAnswer,
    7. String position,
    8. int sortOrder,
    )?, {
  2. 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 id,  String? chunkId,  String topicId,  String questionType,  String questionText,  String? expectedAnswer,  String position,  int sortOrder)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _ReadingQuestion() when $default != null:
return $default(_that.id,_that.chunkId,_that.topicId,_that.questionType,_that.questionText,_that.expectedAnswer,_that.position,_that.sortOrder);case _:
  return orElse();

}
