when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String? id,
    2. String? matrixId,
    3. TenvioItemLocation location,
    4. String? address,
    5. DateTime? pickupDate,
    6. Map<String, dynamic> customProperties,
    7. String? warehouseId,
    )
)

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? matrixId, @TenvioItemLocationConverter()  TenvioItemLocation location,  String? address, @TimestampOrNullConverter()  DateTime? pickupDate,  Map<String, dynamic> customProperties,  String? warehouseId)  $default,) {final _that = this;
switch (_that) {
case _TenvioItemInput():
return $default(_that.id,_that.matrixId,_that.location,_that.address,_that.pickupDate,_that.customProperties,_that.warehouseId);case _:
  throw StateError('Unexpected subclass');

}
