maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>({
  1. TResult applePay(
    1. List<ApplePayCartSummaryItem> summaryItems,
    2. List<ApplePayShippingMethod> shippingMethods,
    3. List<ApplePaySheetError>? errors
    )?,
  2. 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( List<ApplePayCartSummaryItem> summaryItems,  List<ApplePayShippingMethod> shippingMethods,  List<ApplePaySheetError>? errors)?  applePay,required TResult orElse(),}) {final _that = this;
switch (_that) {
case _PlatformPaySheetUpdateParams() when applePay != null:
return applePay(_that.summaryItems,_that.shippingMethods,_that.errors);case _:
  return orElse();

}
}
