implement static method

NSMenuItemValidation implement({ required bool validateMenuItem_(NSMenuItem menuItem), bool $keepIsolateAlive = true, })

Builds an object that implements the NSMenuItemValidation 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 NSMenuItemValidation implement({
  required bool Function(NSMenuItem) validateMenuItem_,
  bool $keepIsolateAlive = true,
}) {
  final builder = objc.ObjCProtocolBuilder(debugName: 'NSMenuItemValidation');
  NSMenuItemValidation.validateMenuItem_.implement(
    builder,
    validateMenuItem_,
  );
  builder.addProtocol($protocol);
  return NSMenuItemValidation.castFrom(
    builder.build(keepIsolateAlive: $keepIsolateAlive),
  );
}
