map<TResult extends Object?> method

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

A switch-like method, using callbacks.

Callbacks receives the raw object, upcasted. It is equivalent to doing:

switch (sealedClass) {
  case final Subclass value:
    return ...;
  case final Subclass2 value:
    return ...;
}
