)

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? fromAssetId,  Asset? fromAsset,  String? sensorId,  Sensor? sensor,  String? toAssetId,  Asset? toAsset,  double? totalLiters, @TimestampOrNullConverter()  DateTime? startAt, @TimestampOrNullConverter()  DateTime? endAt,  bool? isReady,  bool? inProgress,  bool? isValidated)  $default,) {final _that = this;
switch (_that) {
case _AtsPossibleExit():
return $default(_that.id,_that.fromAssetId,_that.fromAsset,_that.sensorId,_that.sensor,_that.toAssetId,_that.toAsset,_that.totalLiters,_that.startAt,_that.endAt,_that.isReady,_that.inProgress,_that.isValidated);case _:
  throw StateError('Unexpected subclass');
