whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. @EmbedExternalViewConverter() EmbedExternalView? view,
    2. @RepoStrongRefConverter() List<RepoStrongRef>? associatedRefs,
    3. List<Map<String, dynamic>>? associatedRecords,
    4. Map<String, dynamic>? $unknown,
    )?
)

A variant of when that fallback to returning null

It is equivalent to doing:

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

Implementation

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? Function(@EmbedExternalViewConverter()  EmbedExternalView? view, @RepoStrongRefConverter()  List<RepoStrongRef>? associatedRefs,  List<Map<String, dynamic>>? associatedRecords,  Map<String, dynamic>? $unknown)?  $default,) {final _that = this;
switch (_that) {
case _EmbedGetEmbedExternalViewOutput() when $default != null:
return $default(_that.view,_that.associatedRefs,_that.associatedRecords,_that.$unknown);case _:
  return null;

}
}
