maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. String cid,
    3. String playlist,
    4. String? thumbnail,
    5. String? alt,
    6. @AspectRatioConverter() AspectRatio? aspectRatio,
    7. @EmbedVideoViewPresentationConverter() EmbedVideoViewPresentation? presentation,
    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 cid,  String playlist,  String? thumbnail,  String? alt, @AspectRatioConverter()  AspectRatio? aspectRatio, @EmbedVideoViewPresentationConverter()  EmbedVideoViewPresentation? presentation,  Map<String, dynamic>? $unknown)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _EmbedVideoView() when $default != null:
return $default(_that.$type,_that.cid,_that.playlist,_that.thumbnail,_that.alt,_that.aspectRatio,_that.presentation,_that.$unknown);case _:
  return orElse();

}
