maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>({
  1. TResult relationship(
    1. Relationship data
    )?,
  2. TResult notFoundActor(
    1. NotFoundActor data
    )?,
  3. TResult unknown(
    1. Map<String, dynamic> data
    )?,
  4. 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( Relationship data)?  relationship,TResult Function( NotFoundActor data)?  notFoundActor,TResult Function( Map<String, dynamic> data)?  unknown,required TResult orElse(),}) {final _that = this;
switch (_that) {
case UGraphGetRelationshipsRelationshipsRelationship() when relationship != null:
return relationship(_that.data);case UGraphGetRelationshipsRelationshipsNotFoundActor() when notFoundActor != null:
return notFoundActor(_that.data);case UGraphGetRelationshipsRelationshipsUnknown() when unknown != null:
return unknown(_that.data);case _:
  return orElse();

}
