map<TResult extends Object?> method

  1. @optionalTypeArgs
TResult map<TResult extends Object?>({
  1. required TResult embedImages(
    1. UFeedPostEmbedEmbedImages value
    ),
  2. required TResult embedVideo(
    1. UFeedPostEmbedEmbedVideo value
    ),
  3. required TResult embedExternal(
    1. UFeedPostEmbedEmbedExternal value
    ),
  4. required TResult embedRecord(
    1. UFeedPostEmbedEmbedRecord value
    ),
  5. required TResult embedRecordWithMedia(
    1. UFeedPostEmbedEmbedRecordWithMedia value
    ),
  6. required TResult unknown(
    1. UFeedPostEmbedUnknown 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 ...;
}
