maybeMap<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeMap<TResult extends Object?>({
  1. TResult text(
    1. TextComponent value
    )?,
  2. TResult card(
    1. CardComponent value
    )?,
  3. TResult carousel(
    1. CarouselComponent value
    )?,
  4. TResult productList(
    1. ProductListComponent value
    )?,
  5. TResult image(
    1. ImageComponent value
    )?,
  6. TResult buttonGroup(
    1. ButtonGroupComponent value
    )?,
  7. TResult swatchGrid(
    1. SwatchGridComponent value
    )?,
  8. TResult hostSlot(
    1. HostSlotComponent value
    )?,
  9. required TResult orElse(),
})

A variant of map that fallback to returning orElse.

It is equivalent to doing:

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

Implementation

@optionalTypeArgs TResult maybeMap<TResult extends Object?>({TResult Function( TextComponent value)?  text,TResult Function( CardComponent value)?  card,TResult Function( CarouselComponent value)?  carousel,TResult Function( ProductListComponent value)?  productList,TResult Function( ImageComponent value)?  image,TResult Function( ButtonGroupComponent value)?  buttonGroup,TResult Function( SwatchGridComponent value)?  swatchGrid,TResult Function( HostSlotComponent value)?  hostSlot,required TResult orElse(),}){
final _that = this;
switch (_that) {
case TextComponent() when text != null:
return text(_that);case CardComponent() when card != null:
return card(_that);case CarouselComponent() when carousel != null:
return carousel(_that);case ProductListComponent() when productList != null:
