maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. String text,
    3. UDraftPostLabels? labels,
    4. List<DraftEmbedImage>? embedImages,
    5. List<DraftEmbedVideo>? embedVideos,
    6. List<DraftEmbedExternal>? embedExternals,
    7. List<DraftEmbedRecord>? embedRecords,
    8. Map<String, dynamic>? $unknown,
    )?, {
  2. required TResult orElse(),
})

A variant of when that fallback to an orElse callback.

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return orElse();
}

Implementation

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult Function( String $type,  String text, @UDraftPostLabelsConverter()  UDraftPostLabels? labels, @DraftEmbedImageConverter()  List<DraftEmbedImage>? embedImages, @DraftEmbedVideoConverter()  List<DraftEmbedVideo>? embedVideos, @DraftEmbedExternalConverter()  List<DraftEmbedExternal>? embedExternals, @DraftEmbedRecordConverter()  List<DraftEmbedRecord>? embedRecords,  Map<String, dynamic>? $unknown)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _DraftPost() when $default != null:
return $default(_that.$type,_that.text,_that.labels,_that.embedImages,_that.embedVideos,_that.embedExternals,_that.embedRecords,_that.$unknown);case _:
  return orElse();

}
