A macOS/iOS Flutter plugin that provides access to the Foundation URL Loading System.

A macOS/iOS Flutter plugin that provides access to the Foundation URL Loading System.

Using the Foundation URL Loading System, rather than the socket-based dart:io HttpClient implemententation, has several advantages:

1. It automatically supports iOS/macOS platform features such VPNs and HTTP proxies.
2. It supports many more configuration options such as only allowing access through WiFi and blocking cookies.
3. It supports more HTTP features such as HTTP/3 and custom redirect handling.

Using

The easiest way to use this library is via the the high-level interface defined by package:http Client.

This approach allows the same HTTP code to be used on all platforms, while still allowing platform-specific setup.

late Client client;
if (Platform.isIOS) {
  final config = URLSessionConfiguration.ephemeralSessionConfiguration()
    ..allowsCellularAccess = false
    ..allowsConstrainedNetworkAccess = false
    ..allowsExpensiveNetworkAccess = false;
  client = CupertinoClient.fromSessionConfiguration(config);
} else {
  client = IOClient(); // Uses an HTTP client based on dart:io
}

final response = await client.get(Uri.https(
    'www.googleapis.com',
    '/books/v1/volumes',
    {'q': 'HTTP', 'maxResults': '40', 'printType': 'books'}));

You can also use the Foundation URL Loading System API directly.

final url = Uri.https(
    'www.googleapis.com',
    '/books/v1/volumes',
    {'q': 'HTTP', 'maxResults': '40', 'printType': 'books'});
final session = URLSession.sharedSession();
final task = session.dataTaskWithCompletionHandler(URLRequest.fromUrl(url),
    (data, response, error) {
  if (error == null && response!.statusCode == 200) {
    print(data!.bytes);
  }
});
task.resume();
