maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. Element card,
    2. BillingDetails? billingDetails
    )?, {
  2. TResult id(
    1. String id
    )?,
  3. TResult token(
    1. CardTokenPaymentMethod card,
    2. BillingDetails? billingDetails
    )?,
  4. required TResult orElse(),
})

A variant of when that fallback to an orElse callback.

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return orElse();
}

Implementation

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult Function(@ElementConverter()  Element card, @JsonKey(name: "billing_details")  BillingDetails? billingDetails)?  $default,{TResult Function( String id)?  id,TResult Function( CardTokenPaymentMethod card, @JsonKey(name: "billing_details")  BillingDetails? billingDetails)?  token,required TResult orElse(),}) {final _that = this;
switch (_that) {
case _CardPaymentMethodRef() when id != null:
return id(_that.id);case _CardPaymentMethodDefault() when $default != null:
return $default(_that.card,_that.billingDetails);case _CardPaymentMethodDetailsToken() when token != null:
return token(_that.card,_that.billingDetails);case _:
  return orElse();

}
