implement static method

NSCollectionViewPrefetching implement({
  1. required void collectionView_prefetchItemsAtIndexPaths_(
    1. NSCollectionView,
    2. NSArray
    ),
  2. void collectionView_cancelPrefetchingForItemsAtIndexPaths_(
    1. NSCollectionView,
    2. NSArray
    )?,
  3. bool $keepIsolateAlive = true,
})

Builds an object that implements the NSCollectionViewPrefetching protocol. To implement multiple protocols, use addToBuilder or objc.ObjCProtocolBuilder directly.

If $keepIsolateAlive is true, this protocol will keep this isolate alive until it is garbage collected by both Dart and ObjC.

Implementation

static NSCollectionViewPrefetching implement({
  required void Function(NSCollectionView, objc.NSArray)
  collectionView_prefetchItemsAtIndexPaths_,
  void Function(NSCollectionView, objc.NSArray)?
  collectionView_cancelPrefetchingForItemsAtIndexPaths_,
  bool $keepIsolateAlive = true,
}) {
  final builder = objc.ObjCProtocolBuilder(
    debugName: 'NSCollectionViewPrefetching',
  );
  NSCollectionViewPrefetching.collectionView_prefetchItemsAtIndexPaths_
      .implement(builder, collectionView_prefetchItemsAtIndexPaths_);
  NSCollectionViewPrefetching
      .collectionView_cancelPrefetchingForItemsAtIndexPaths_
      .implement(
        builder,
        collectionView_cancelPrefetchingForItemsAtIndexPaths_,
      );
  builder.addProtocol($protocol);
  return NSCollectionViewPrefetching.castFrom(
    builder.build(keepIsolateAlive: $keepIsolateAlive),
  );
