implement static method

NSFilePromiseProviderDelegate implement({
  1. required NSString filePromiseProvider_fileNameForType_(
    1. NSFilePromiseProvider,
    2. NSString
    ),
  2. required void filePromiseProvider_writePromiseToURL_completionHandler_(
    1. NSFilePromiseProvider,
    2. NSURL,
    3. ObjCBlock<Void Function(NSError?)>
    ),
  3. NSOperationQueue operationQueueForFilePromiseProvider_(
    1. NSFilePromiseProvider
    )?,
  4. bool $keepIsolateAlive = true,
})

Builds an object that implements the NSFilePromiseProviderDelegate 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 NSFilePromiseProviderDelegate implement({
  required objc.NSString Function(NSFilePromiseProvider, objc.NSString)
  filePromiseProvider_fileNameForType_,
  required void Function(
    NSFilePromiseProvider,
    objc.NSURL,
    objc.ObjCBlock<ffi.Void Function(objc.NSError?)>,
  )
  filePromiseProvider_writePromiseToURL_completionHandler_,
  NSOperationQueue Function(NSFilePromiseProvider)?
  operationQueueForFilePromiseProvider_,
  bool $keepIsolateAlive = true,
}) {
  final builder = objc.ObjCProtocolBuilder(
    debugName: 'NSFilePromiseProviderDelegate',
  );
  NSFilePromiseProviderDelegate.filePromiseProvider_fileNameForType_
      .implement(builder, filePromiseProvider_fileNameForType_);
  NSFilePromiseProviderDelegate
      .filePromiseProvider_writePromiseToURL_completionHandler_
      .implement(
        builder,
        filePromiseProvider_writePromiseToURL_completionHandler_,
      );
  NSFilePromiseProviderDelegate.operationQueueForFilePromiseProvider_
      .implement(builder, operationQueueForFilePromiseProvider_);
  builder.addProtocol($protocol);
  return NSFilePromiseProviderDelegate.castFrom(
    builder.build(keepIsolateAlive: $keepIsolateAlive),
  );
