when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String? payerName,
    2. int? payerSladeCode,
    3. String? memberNumber,
    4. String? memberName,
    5. String? validTo,
    6. String? validFrom,
    )
)

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(@JsonKey(name: 'payer_name')  String? payerName, @JsonKey(name: 'payer_slade_code')  int? payerSladeCode, @JsonKey(name: 'member_number')  String? memberNumber, @JsonKey(name: 'member_name')  String? memberName, @JsonKey(name: 'valid_to')  String? validTo, @JsonKey(name: 'valid_from')  String? validFrom)  $default,) {final _that = this;
switch (_that) {
case _Cover():
return $default(_that.payerName,_that.payerSladeCode,_that.memberNumber,_that.memberName,_that.validTo,_that.validFrom);case _:
  throw StateError('Unexpected subclass');
