maybeWhen<TResult extends Object?> method

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

}
}
