when<TResult extends Object?> method

@optionalTypeArgs TResult when<TResult extends Object?>(TResult $default(String? cnpj, String? name, String? address, String? mun, String? freightMod, String? federalUnit, String? businessNumber, String? vehiclePlate, String? vehicleUf, String? vehicleName, String? destination, String? driver, String? origin, String? stateRegistration,))

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? cnpj,  String? name,  String? address,  String? mun,  String? freightMod,  String? federalUnit,  String? businessNumber,  String? vehiclePlate,  String? vehicleUf,  String? vehicleName,  String? destination,  String? driver,  String? origin,  String? stateRegistration)  $default,) {final _that = this;
switch (_that) {
case _AtsTransportInformation():
return $default(_that.cnpj,_that.name,_that.address,_that.mun,_that.freightMod,_that.federalUnit,_that.businessNumber,_that.vehiclePlate,_that.vehicleUf,_that.vehicleName,_that.destination,_that.driver,_that.origin,_that.stateRegistration);case _:
  throw StateError('Unexpected subclass');
