import 'package:new_httpdns/new_httpdns.dart';

await NewHttpdns.init(
  appId: 'app1f1ndpo9',
  primaryServiceHost: 'httpdns-a.example.com',
  backupServiceHost: 'httpdns-b.example.com', // optional
  servicePort: 443,
  secretKey: 'your-sign-secret', // optional if sign is enabled
);

await NewHttpdns.setHttpsRequestEnabled(true);
await NewHttpdns.build();

2. Resolve

final result = await NewHttpdns.resolveHostSyncNonBlocking(
  'api.business.com',
  ipType: 'both',
);

final ipv4 = result['ipv4'] ?? <String>[];
final ipv6 = result['ipv6'] ?? <String>[];

3. Official HTTP Adapter (IP + Host)

final adapter = NewHttpdns.createHttpAdapter(
  options: const NewHttpdnsAdapterOptions(
    ipType: 'auto',
    connectTimeoutMs: 3000,
    readTimeoutMs: 5000,
    allowInsecureCertificatesForDebugOnly: false,
  ),
);

final resp = await adapter.request(
  Uri.parse('https://api.business.com/v1/ping'),
  method: 'GET',
  headers: {'Accept': 'application/json'},
);

print(resp.statusCode);
print(resp.usedIp);

Behavior is fixed:

Resolve host by /resolve.
Connect to resolved IP over HTTPS.
Keep Host header as the real business domain.
No fallback to domain direct request.

4. Public Errors

TLS_EMPTY_SNI_FAILED
HOST_ROUTE_REJECTED
RESOLVE_SIGN_INVALID

5. Deprecated Params Removed
