when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<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 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 webhookId,  String eventType,  Map<String, dynamic> payload,  int? responseStatus,  String? responseBody,  int attempt,  DateTime? deliveredAt,  DateTime? nextRetryAt,  DateTime createdAt)  $default,) {final _that = this;
switch (_that) {
case _WebhookDelivery():
return $default(_that.id,_that.webhookId,_that.eventType,_that.payload,_that.responseStatus,_that.responseBody,_that.attempt,_that.deliveredAt,_that.nextRetryAt,_that.createdAt);case _:
  throw StateError('Unexpected subclass');

}
