whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String id,
    2. String webhookId,
    3. String eventType,
    4. Map<String, dynamic> payload,
    5. int? responseStatus,
    6. String? responseBody,
    7. int attempt,
    8. DateTime? deliveredAt,
    9. DateTime? nextRetryAt,
    10. DateTime createdAt,
    )?
)

A variant of when that fallback to returning null

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return null;
}

Implementation

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? Function( String id,  String webhookId,  String eventType, @JsonKey(fromJson: _castMap)  Map<String, dynamic> payload,  int? responseStatus,  String? responseBody,  int attempt,  DateTime? deliveredAt,  DateTime? nextRetryAt,  DateTime createdAt)?  $default,) {final _that = this;
switch (_that) {
case _WebhookDeliveryModel() when $default != null:
return $default(_that.id,_that.webhookId,_that.eventType,_that.payload,_that.responseStatus,_that.responseBody,_that.attempt,_that.deliveredAt,_that.nextRetryAt,_that.createdAt);case _:
  return null;

}
