when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. String? comment,
    3. DateTime? executeAt,
    4. DateTime? executeAfter,
    5. DateTime? executeUntil,
    6. Map<String, dynamic>? $unknown,
    )
)

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 $type,  String? comment,  DateTime? executeAt,  DateTime? executeAfter,  DateTime? executeUntil,  Map<String, dynamic>? $unknown)  $default,) {final _that = this;
switch (_that) {
case _ScheduleTakedownEvent():
return $default(_that.$type,_that.comment,_that.executeAt,_that.executeAfter,_that.executeUntil,_that.$unknown);case _:
  throw StateError('Unexpected subclass');

}
}
