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
    ),
})

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 ...;
}

Implementation

final _that = this;
switch (_that) {
case TextComponent():
return text(_that);case CardComponent():
return card(_that);case CarouselComponent():
return carousel(_that);case ProductListComponent():
return productList(_that);case ImageComponent():
return image(_that);case ButtonGroupComponent():
return buttonGroup(_that);}
