safe_url_check library

Utility library to check if an untrusted URL is broken or not.

This makes an HTTP HEAD request after checking that the hostname does not resolve to a private IPv4 address or local unique IPv6 address.

Example

import 'package:safe_url_check/safe_url_check.dart';

Future<void> main() async {
  // Check if https://google.com is a broken URL.
  final exists = await safeUrlCheck(
    Uri.parse('https://google.com'),
    userAgent: 'myexample/1.0.0 (+https://example.com)',
  );
  if (exists) {
    print('The url: https://google.com is NOT broken');
  }
}

Functions

safeUrlCheck(Uri url, {int maxRedirects = 8, String userAgent = defaultUserAgent, HttpClient? client, RetryOptions retryOptions = const RetryOptions(maxAttempts: 3), Duration timeout = const Duration(seconds: 90)}) → Future<bool>

Check if url is available, without allowing access to private networks.
