implement static method

CALayoutManager implement({
  1. CGSize preferredSizeOfLayer_(
    1. CALayer
    )?,
  2. void invalidateLayoutOfLayer_(
    1. CALayer
    )?,
  3. void layoutSublayersOfLayer_(
    1. CALayer
    )?,
  4. bool $keepIsolateAlive = true,
})

Builds an object that implements the CALayoutManager 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 CALayoutManager implement({
  objc.CGSize Function(CALayer)? preferredSizeOfLayer_,
  void Function(CALayer)? invalidateLayoutOfLayer_,
  void Function(CALayer)? layoutSublayersOfLayer_,
  bool $keepIsolateAlive = true,
}) {
  final builder = objc.ObjCProtocolBuilder(debugName: 'CALayoutManager');
  CALayoutManager.preferredSizeOfLayer_.implement(
    builder,
    preferredSizeOfLayer_,
  );
  CALayoutManager.invalidateLayoutOfLayer_.implement(
    builder,
    invalidateLayoutOfLayer_,
  );
  CALayoutManager.layoutSublayersOfLayer_.implement(
    builder,
    layoutSublayersOfLayer_,
  );
  builder.addProtocol($protocol);
  return CALayoutManager.castFrom(
    builder.build(keepIsolateAlive: $keepIsolateAlive),
  );
