map<TResult extends Object?> method

  1. @optionalTypeArgs
TResult map<TResult extends Object?>({
  1. required TResult embedImagesView(
    1. UPostViewEmbedEmbedImagesView value
    ),
  2. required TResult embedVideoView(
    1. UPostViewEmbedEmbedVideoView value
    ),
  3. required TResult embedExternalView(
    1. UPostViewEmbedEmbedExternalView value
    ),
  4. required TResult embedRecordView(
    1. UPostViewEmbedEmbedRecordView value
    ),
  5. required TResult embedRecordWithMediaView(
    1. UPostViewEmbedEmbedRecordWithMediaView value
    ),
  6. required TResult unknown(
    1. UPostViewEmbedUnknown 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 ...;
}
