mapOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? mapOrNull<TResult extends Object?>({
  1. TResult? embedGalleryViewImage(
    1. UEmbedGalleryViewItemsEmbedGalleryViewImage value
    )?,
  2. TResult? unknown(
    1. UEmbedGalleryViewItemsUnknown value
    )?,
})

A variant of map that fallback to returning null.

It is equivalent to doing:

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

Implementation

@optionalTypeArgs TResult? mapOrNull<TResult extends Object?>({TResult? Function( UEmbedGalleryViewItemsEmbedGalleryViewImage value)?  embedGalleryViewImage,TResult? Function( UEmbedGalleryViewItemsUnknown value)?  unknown,}){
final _that = this;
switch (_that) {
case UEmbedGalleryViewItemsEmbedGalleryViewImage() when embedGalleryViewImage != null:
return embedGalleryViewImage(_that);case UEmbedGalleryViewItemsUnknown() when unknown != null:
return unknown(_that);case _:
  return null;

}
