maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. PaymentElementLayoutType type,
    2. bool? defaultCollapsed,
    3. bool? radios,
    4. bool? spacedAccordionItems,
    5. int? visibleAccordionItemsCount,
    )?, {
  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( PaymentElementLayoutType type,  bool? defaultCollapsed,  bool? radios,  bool? spacedAccordionItems,  int? visibleAccordionItemsCount)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _PaymentElementLayout() when $default != null:
return $default(_that.type,_that.defaultCollapsed,_that.radios,_that.spacedAccordionItems,_that.visibleAccordionItemsCount);case _:
  return orElse();

}
}
