implement static method

NSFontChanging implement({
  1. void changeFont_(
    1. NSFontManager?
    )?,
  2. NSFontPanelModeMask validModesForFontPanel_(
    1. NSFontPanel
    )?,
  3. bool $keepIsolateAlive = true,
})

Builds an object that implements the NSFontChanging 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 NSFontChanging implement({
  void Function(NSFontManager?)? changeFont_,
  NSFontPanelModeMask Function(NSFontPanel)? validModesForFontPanel_,
  bool $keepIsolateAlive = true,
}) {
  final builder = objc.ObjCProtocolBuilder(debugName: 'NSFontChanging');
  NSFontChanging.changeFont_.implement(builder, changeFont_);
  NSFontChanging.validModesForFontPanel_.implement(
    builder,
    validModesForFontPanel_,
  );
  builder.addProtocol($protocol);
  return NSFontChanging.castFrom(
    builder.build(keepIsolateAlive: $keepIsolateAlive),
  );
