maybeMap<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeMap<TResult extends Object?>({
  1. TResult embedExternalViewArticle(
    1. UEmbedGetEmbedExternalViewDataEmbedExternalViewArticle value
    )?,
  2. TResult embedExternalViewArticlePublication(
    1. UEmbedGetEmbedExternalViewDataEmbedExternalViewArticlePublication value
    )?,
  3. TResult embedExternalViewGallery(
    1. UEmbedGetEmbedExternalViewDataEmbedExternalViewGallery value
    )?,
  4. TResult embedExternalViewLivestream(
    1. UEmbedGetEmbedExternalViewDataEmbedExternalViewLivestream value
    )?,
  5. TResult unknown(
    1. UEmbedGetEmbedExternalViewDataUnknown value
    )?,
  6. 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( UEmbedGetEmbedExternalViewDataEmbedExternalViewArticle value)?  embedExternalViewArticle,TResult Function( UEmbedGetEmbedExternalViewDataEmbedExternalViewArticlePublication value)?  embedExternalViewArticlePublication,TResult Function( UEmbedGetEmbedExternalViewDataEmbedExternalViewGallery value)?  embedExternalViewGallery,TResult Function( UEmbedGetEmbedExternalViewDataEmbedExternalViewLivestream value)?  embedExternalViewLivestream,TResult Function( UEmbedGetEmbedExternalViewDataUnknown value)?  unknown,required TResult orElse(),}){
