maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. String uri,
    3. String title,
    4. String description,
    5. @BlobConverter() Blob? thumb,
    6. @RepoStrongRefConverter() List<RepoStrongRef>? associatedRecords,
    7. 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 uri,  String title,  String description, @BlobConverter()  Blob? thumb, @RepoStrongRefConverter()  List<RepoStrongRef>? associatedRecords,  Map<String, dynamic>? $unknown)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _EmbedExternalExternal() when $default != null:
return $default(_that.$type,_that.uri,_that.title,_that.description,_that.thumb,_that.associatedRecords,_that.$unknown);case _:
  return orElse();

}
}
